Feature of compact disc player Audio Research CD6

Secondly, the presence of the digital inputs has forced us to think about the future of specialized compact disc player class High End. Few manufacturers are not concerned about the possibility of connecting them to other digital sources so that they will be in demand when the discs themselves come completely out of use.

For those who are familiar with the company’s products, there are no special surprises. Audio Research is one of the pillars of the High End, its enviable reputation to create a model, a top priority in the design of which was the sound quality. After 40 successful years, the company does not intend to change its approach, and compact disc player CD6 – confirmation.

The workmanship is excellent; body seem designed for decades of service. However, we are not convinced of the need to be placed on display bolt heads on the entire surface; perhaps this is a manifestation of the approach Audio Research “working tool is not a luxury”, but why are they not at least equal? We counted three kinds of screws, and a lack of coordination causes a feeling of artisanal crafts. We were also amused by the inscription «Digital compact disc player» (digital compact disc player) on the front panel – as if there are others.

The tray on the top panel; there was very little, and it’s a shame: this configuration eliminates the need for travelers subject tray and motor.

Pushing the lid on the top panel, you will see the compact disc player – transport Philips Pro2. Hold the temptation to poke a finger in the laser – it is too fragile – and do not forget to replace the magnetic disk, otherwise the machine will not operate.

The buttons on the front panel are not very logical; We had to read the labels each time, memorize them and failed, even after a couple of weeks of testing compact disc player CD6. As a result, we often use a conventional remote control – unlike the previous plastic models of this time it is packaged in a metal case. The layout is well thought-out and finishing without any frills.

On the back panel – Four digital inputs: USB, coaxial and optical couple. All of them accept files up to 24 bit / 192 kHz. To use the USB-port, you need to download the appropriate driver. A pair of digital outputs – AES / EBU and coaxial BNC – even more useful to owners of high-quality compact disc player / DAC, as well as those who are going to produce a digital signal processing. It also has the usual assortment of balanced and unbalanced analog connectors.

Digital Home motherboard is mounted near the rear panel to reduce the signal path, and away from the analog loop – to reduce interference. USB-port serves a separate fee from the side.

When creating compact disc player CD6 consider the experience of the development of an even more ambitious digital models – such as CD9 compact disc player and DAC Reference; Like them, CD6 applied to four 24-bit DAC in each channel and two clock pulse generator, one of them corresponds to the frequency of 44.1, 88.2 and 176.4 kHz, the second – 48, 96, 192 kHz. This provides the most accurate digital clock, and as a result, higher-quality sound.

CD6 is equipped with only two filters – “fast” and “slow”; if you like to tinker with the settings, you can increase the sampling frequency of the input signal. When playing back CD, coaxial and optical input can be brought to 176.4, or 192 kHz, depending on the original; USB interface, these figures are lower – 88.2 or 96 kHz.

When tested with the reference amplifier Bryston BP26 / 4BSST2 and AC ATC SCM 50 us more like “slow” filter function is disabled resampling. Perhaps you will sound better with different combinations of settings.

It is necessary to put the compact disc player and CD6 instantly captivates remarkably natural sound, full of details and nuances. Meticulous dynamics CD6 in the performance of “Romeo and Juliet” by Tchaikovsky struck us in the heart. It has a large music scene with the exact location of tools and physically perceptible depth. High-detailed provides a richness of timbre and texture of each instrument.

The especially impressive scale of sound, when required by the music, and excellent dynamics at any volume, inherent only to the most powerful model. The player Audio Research peculiar enviable composure; even in the most intense moments of the game it does not lose its naturalness. We like it a smooth tonal balance and fair treatment to all the tools. Few Hi-Fi-capable components are put on the forefront of the music, not its sound character. New compact disc player CD6 – the very rare case.

In Into My Arms Nick Cave, we are particularly impressed by the submission of his cracked voice. The sound is all that we like: the natural heat, density, and excellent micro drivers. CD6 shows a master class by expanding the harmonic piano beautifully written out of the layers.

Digital inputs have pleased no less; pleasant impression created Plays compact disc player, reinforced song files group Rolling Stones (Gimme Shelter in the format of 24-bit / 88.2 kHz) and Michael Jackson (Billie Jean, 24 / 176.4). They fully befitting inherent vigor; despite the sophistication of nature, CD6 able, if necessary, issue a powerful drive and open aggression. It is not often we can hear such a perfect sound.

If you are looking for an integrated compact disc player high-end, look for CD6. His sound – one of the best in this price range, and those who are a little CD-drive, a great handy built-in compact disc player / DAC. This is a great component of any system of High-End-class.

Price – compact disc player: $ 13,550

Rating – compact disc player: 5

PROS – compact disc player: Wonderful midrange; enormity; Strong dynamics; good in the role of the compact disc player / DAC; workmanship

CONS – compact disc player: Decorating is not perfect; not the most stylish remote control

VERDICT – compact disc player: A great option for those who want a high-quality compact disc player

Feature of headphone amp Pathos Converto

I must say that if you prefer to connect the DAC to only desktop and laptop computers, you run the risk of literally missed many a deaf ear. Sound Converto in this case, and somewhat dry it slightly lacks clarity – so that we would recommend using a high-quality network player or CD-player.

In this case, the composition Highway Star Deep Purple’s very demanding on an amplifier with headphone amp Beyerdynamic DT880 served detail, every nuance of vengeance as accurately as possible. Wide stereo image, you can only find fault localization tools: they are slightly smeared on the virtual stage. Nevertheless, the tonal balance is perceived as equal, and the drive passed in full.

If the speakers all questions to the stereo removed and maintains sound clarity and rhythm. We can not say that the bass much – but enough bass tight and very fast. Vocals clearly defined – so that in the recording of a live concert of Patricia Kaas Toute La Musique all perfectly audible tone of voice and emotional fulfillment rolls.

In classical music, such as “Romeo and Juliet” by Prokofiev, authentically represented the deepest bass (that’s when he plays into the hands of restraint Converto), HF-friendly and transparent. DAC/headphone amp perfectly fulfills any volume differences and the dynamic range is very large. This study tracks so well that almost all tools without any problems are identified and distinguished.

Thus, despite the rather aggressive exterior, Pathos Converto gently and carefully brings to the listener the slightest nuances of the music, not allowing himself no gag. Yes, it is necessary to add the high-quality digital source to minimize possible jitter – but this investment will always pay off.

In detail of headphone amp Pathos Converto

The DAC / headphone amp applied fully balanced circuit, and on the back there are not only plenty of inputs but also the balance control channels and the gain for the headphone output.

Inputs are selected button on the front panel, there is a very impressive and is accompanied by clicks of the relay. The absence of labels does not interfere – all the same switching occurs sequentially, but the vertical lights, illuminated in blue – a nice touch.

Price: $ 1820

Pros: Honest sound without embellishments

Cons: Expands only qualitative source

Verdict: If you are not sure about buying quality digital source, the rest – caring DAC / headphone amp

The device is designed to improve the sound quality. In particular – complete headphones. Even Apple, they are far from ideal.

Feature of Mobile amplifier

The product looks good and does not require its own power supply. Energy gadget receives directly from the mobile amplifier device.

There are contraindications. Talk to your doctor.

A key feature of the amplifier – the module DAC. The above guarantees support high-resolution audio. Namely – 24 bit / 192 kHz.

First of all AQUA for “apple” tablets and smartphones. It connects to the connector invention Lightning. However, fans of the other platforms can use the adapter (micro-USB).

If you believe the developers, the headphones fit all. Including having a decent resistance.

The price of the mobile amplifier is 59 dollars. Authors of the project on Kickstarter has raised the necessary amount for mass production. The release will take place in November this year.

The company TAD is not too invested in marketing so that many readers it may be unfamiliar. It belongs to Pioneer, its name means Technical Audio Devices (Technical Audio Devices), and in the beginning the company produced high-performance studio AS.Krepky TAD DA1000 weighs no less than 16.5 kg. Most of the weight falls on the body – very durable and perfectly damped. The quality of the finishing and perfect as to be in this price range: every detail of the body delights precision machining and assembly.

This DAC is a lot of different connectors, as well as – which is rare among premium devices – remote control of comparable quality

The front display is too small; it perfectly readable even from a distance, but the information is too scarce. Thick plate body partially blocking the screen when viewed from above.

Inside the case, you can see the spacious bay adapter, thoughtful layout, and to estimate how much attention is given to noise reduction.

Feature of TAD DA1000

In TAD DA1000 good range of connectors; digital inputs presented USB, AES / EBU, optical and coaxial pair. USB-port accepts files with sample rates up to 384 kHz, optical input is limited to 96 kHz. The other two are intermediate inputs, supporting standards up to 192 kHz. As usual in this category, there are balanced and unbalanced outputs – DAC sounds perfectly in both cases. On the front is a 6.3-mm headphone output with volume control.

At once, we do not have to complain about the quality of the remote control supplied with the equipment High-End-class. This very pleasant to the touch and is very convenient in the case.

Start listening, we quickly realized that to really love the sound of the TAD DA1000. Basically, we tested it with the reference system, which includes a network player Naim NDS / 555PS, MacBook program Pure Music, preamplifier / power amplifier Bryston BP26 / 4B SST2 and speakers ATC SCM50.

We almost immediately decided to abandon the Bryston Pre and give the signal to the TAD DA1000 directly to the power amplifier. This approach significantly increases the transparency and detail, barely losing (as often happens) in density, dynamics, and drive.

Miles Davis album Sketches Of Spain in the CD-copy is executed just fine. The detail unimaginably high; TAD unearths the quietest instrument parts so earnestly, as if it affects his life. This study does not result in the degree of stiffness or roughness sound. We were captivated by soft tone character for all analytic and high-resolution sound TAD becomes sterile. The poor quality of records is always felt, but does not appear in the foreground.

The more we listen, the more admired TAD DA1000 ability to maintain the acoustic space around the instruments and perfection Micro dynamic. But do not jump to conclusions; Gimme Shelter Rolling Stones group in 24-bit / 88.2 kHz makes it clear that, if necessary, the DAC is able to set the heat.

Headphone showed himself no worse. And the album Kanye West My Beautiful Dark Twisted Fantasy sampled at 16-bit / 44.1 kHz, and the Berlioz song cycle “Summer Nights” with the parameters of 24-bit / 192 kHz exceptionally good. A variety of headphones – from Grado PS500 to BeyerDynamics T1 – TAD DA1000 played with the same great sound character is not different from that obtained with the line outputs.

Conclusion of TAD DA1000

TAD DA1000 – one of the most talented digital to analog converters, which we have seen. We never distinguished as much detail in the familiar digital files; while its inherent sound rare vitality and drive. It is always interesting to listen to, can boast not every competitor. If you want to get a glimpse of the tops of the DAC technology, TAD DA1000 will provide it to the fullest.

All around us is changing so fast, that sooner or later there is a problem of lack of a link to the system components. For example, you want to buy headphones that are now producing many Hi-Fi-company, but your system does not yield to them (and it happens), or it is not very good. Or maybe you want to listen to music on your PC, not only in the headphones, but also through the speakers, and in both cases with good sound quality.

These and other cases are offered a wide range of portable or small-sized products having inherently analog converter. This segment applies NuForce Icon DAC.

On the front panel – the volume knob and select inputs

This small device (H × W × D: 15 × 2,5 × 11 cm) connected to the mains via the supplied power supply and can be mounted vertically on a stand or just lie on your side. Icon DAC has stereo inputs – RCA and 3.5 mm – as well as USB-port type B and outputs: analog and digital coaxial RCA.

Still have a 6.3-mm headphone output; its gain stage is powerful enough to work with 600-ohm models. Asynchronous USB-port accepts files with sample rates up to 24 bit / 96 kHz and DSD-streams being downloaded to the PC corresponding driver and the only compatible player. It also supports OTG-technology for smartphones running Android.

Sound Icon DAC with headphone output has high brightness, it is necessary to consider in the selection of the components of the audio section. But with the PC and Hi-Fi-system this DAC exhibits a more balanced character. CD-copy of the album Love by The Beatles played vigorously, rhythmically, in detail; music scene spacious, well-placed elements compositions on it. Recognizable vocals, lively and emotional.

Even better things with HD-audio – the sound is quite noticeable is more refined and smoother. “Symphonic Dances” Rachmaninov format 24/96 executed on a large scale, with the depth of the melodic lines and votes tools sharp and mobile RF and weighty bass.

NuForce Icon DAC – a versatile device with the sound quality, it is consistent with its price category, however, to enter the headphones have a claim.

Price: $ 550

Pros: A set of connections; function preamplifier; quality sound by USB; support for HD-Audio; dimensions

Cons: Brightens the sound from the headphone output, especially when connecting analog source

Verdict: magic wand that will increase the versatility of your Hi-Fi-system

Music has become a matter of personal, and thus the traditional components that you previously shared with others, now collected in one box, which belongs only to you

Oppo company better known for its multi-functional Blu-ray-players, who at one time became a breakthrough: in addition to Blu-ray, they read all available media, including SACD and DVD-Audio, could play the files, and even disk images over the network. It is not surprising that the company drew attention to the rapidly growing segment of the headphones, releasing not only a specialized amplifier HA-1, but premium headphones PM-1.

Despite, in general, nekopeechnuyu price by today’s standards HA-1 can not be attributed to the expensive devices – just look at the gorgeous and heavy body, available with an impressive list of features, and if you’re lucky, then look under the cover, as you will inevitably come to the conclusion that for the money Oppo offers not that many, but a lot.

In addition to classic headphone amplifier with XLR and RCA-inputs at your disposal will be a DAC (on-chip ESS 9018) with coaxial, optical and USB-in (at the receiver XMOS), allows you to connect both classical analog and digital sources, as well as PC and listen high resolution files (including DSD-format data DoP). In addition, the device is equipped with a USB-connector on the front panel allows you to connect and play music with the products Apple. For completeness, happiness owners apple gadgets are not enough unless the AirPlay, but holders of advanced devices on Android, no doubt, appreciate Bluetooth-enabled codec AptX.

Front panel HA-1 adorns a huge graphical display that really want to touch, to get to a particular function. But no, he did not touch, and the menu selection or the desired input by rotating the multifunction knob to the left of it. This is contrary to modern ergonomic fashion, but, however, does not overshadow the work with Oppo: firstly, the device has a handy remote control with direct selection of inputs, and secondly, the big screen can accommodate not only beautiful screen saver in the form of spectrograms and dial indicators, but also to bring all the necessary information. This is the first USB-DAC on our memory, which shows not only a bit, but the number of bits of the incoming digital signal, which, in our opinion, is very important when working with a PC, and which can not wait to count anything.

The sound from the unit price is also ahead – feel free to use it with the most expensive headphones that you can afford. True, you must first find a suitable device for this class of power – believe me, when you connect to our Reference SACD-player Esoteric X-03, which costs about five times more expensive, feelings of inferiority does not arise. This applies particularly to the analog inputs, and the choice, RCA or XLR, depends on what you are using headphones. Balanced connection provides more details on the edges of the range and better dynamics, which is very evident in Tchaikovsky’s Fourth Symphony, but with headphones Beyerdynamic T-1 (harsh in the performance of classical music), we chose to use the RCA-input, giving a more pleasant and focused on musical lines sound . No less impressive and DAC: When connecting to transport high-end “Cantata” Bach performed by RIAS-Kammerchor distinguishes the full, deep study, and only a slight simplification of timbres of voices and instruments indicates that the device is not in front of us from the High-End-category.

Realizing that based on Oppo can build a relatively affordable, but high-end system for listening to music from your PC, we had pinned hopes to USB, especially in light of the outstanding features of this digital giant as the Oppo. Alas, if the aid was not intended to fairly expensive USB-cable Black Rhodium Star ($ 230), the famous Scherzo of Tchaikovsky’s Fourth Symphony (16 / 44.1) would pale, confused rhythmic and dynamic accents. Of course, the files of high resolution bit less critical to the quality of the connector, at least in relation to the rhythm of the sound. Still Daina Krall Temptation format 24/96 with our basic, but good enough Supra USB cable sounds somewhat simplistically-jerky, and the singer and musicians pull the party tired and ragged, as if at a concert in the country club. It is necessary to change the cable on the Black Rhodium or use cables with active power (Astintrew Concord) – and everything falls into place. Even DSD-recording of the concert Dave Brubeck varies greatly depending on the cable used. One conclusion: if you are going to use as the source computer, select the coolest USB-connector that you can afford.

Because of listening to music c portable devices originally special expectations we had, it is quite melodic and coherent execution of Jacques Loussier Chopin nocturnes stored on your iPod, worthy of respect. Of course, much depends on the quality of the original soundtrack – a beautiful, rich record Eternal collective Branford Marsalis is not able to kill even a basic codec Bluetooth.

And now the fun part. Let’s take off the headphones and connect Oppo HA-1 to the power amplifier (or use balanced cables to a pair of studio monitors – not to lose the informational content, to which you are accustomed to with headphones). You’d be surprised how confident the device works as a preamplifier, even as part of the road system. In addition to the formal criteria of sound pleasing music, exciting filing records, whether for analog or digital inputs.

In detail

HA-1 is equipped with two outputs for headphones: 6.3 mm jack and XLR 4 pin. The latter provides the separation of earth conductor signals left and right channels, thereby greatly increasing the sound quality (especially noticeable in the transfer of the fine details of what we were able to assess the example of brand Oppo PM-1, equipped with two sets of wires). Unfortunately, this standard has not yet become widespread, but if your headphones to the replacement of the cable, we recommend you contact a specialized center of the cable, that you have made it to order.

In general, Oppo HA-1 – gentleman of many awards, a wonderful headphone amplifier with a very good DAC (albeit with a rather critical to the cable USB-in) and an excellent preamp. It can be used as a multifunctional center personal system comprising headphones not only, but also couple professional monitors.

Price: $ 1,550

Pros: The quality of manufacture; many functions and interfaces; great sound in the headphones, especially with the output XLR 4pin; works fine as a preamplifier

Cons: Sound from the USB-port can be a very decent and frankly poor – requires high-quality and expensive cable

Verdict: A wonderful version of a personal system with the ability to connect both the headphones and the active speaker

We continue this newly acquainted with the products of the British company Astin Trew. Her line of Concord is still in the formative stage; Release of the scheduled transport CD-integrated amplifier, DAC and possibly something else is only available to customers until the last of these components.

This marker device intended to be placed in the rack – your PC will have to settle with him. At Astin Trew Concord DAC 1 USB is the digital inputs for every occasion: AES \ EBU, SPDIF connectors BNC, RCA and TOSLINK, and even non-certified I2S (we met at a component PS Audio), HDMI-cable connected to a compatible source – is planned that they will be CD-range transport from Concord. But the hottest normal user an option – it’s all the same computer. And for him a choice of FireWire or much more common USB-port – asynchronous implemented on-chip XMOS.

Even in the external design DAC Astin Trew feel special corporate approach

There are two outputs: balanced XLR and unbalanced tube stage equipped with RCA. Digital to analog conversion is done a couple of chips Burr-Brown PCM1794.

Developers Astin Trew Concord DAC 1 USB traditionally have made great efforts to combat the interference of different origin; to this end, shall apply six separate power supplies for the internal circuitry, as well as body vibration-proof design – even its walls are covered with a special material.

Comparing the sound track CD, read transport Esoteric X-03 connected to the coaxial input Concord DAC 1, and copies of the PC via USB-port, we found that playing music from a computer that manages the DAC is not worse than in the first case. Therefore, we focused on listening to it with the more modern and promising source.

As a rule, the sound quality when balanced connection above, but DAC Astin Trew RCA-output has a feature – lamp circuit. This gives an effect. For example, the suite “Mars” from “The Planets” Holst when connecting the amplifier to the XLR-connectors supplied powerful, big, dynamic, emotionally rich. But we no longer liked the sound via the RCA-out: details a little bit less, but the music is much better organized information, in a spacious stage more air, and is particularly noteworthy that the bass noticeably bigger and deeper, and they are velvety, but the texture and emphasize wealth sound and splendor. Microdrivers also more elaborate and expressive, and RF – rounded and mobile, without that crystal fragility that we saw with the XLR.

HD-audio gives even better results. In the album Ten Lives Gwyneth Herbert format 24/48 bass line filled, elastic rhythm and clear vocals perfectly focused and very lively. And again, we prefer the lamp output, enjoying the smooth and refined detail that it provides.

Astin Trew Concord DAC 1 USB – rather remarkable component. He has a comprehensive set of inputs and two distinct variants of sound – to choose from. We recommend a closer look.

Price: $ 7500

Pros: Variety of inputs; balanced and “tube” outputs sound quality on both

Cons: No support for DSD; would not be an extra level control

Verdict: Solid DAC with a number of useful features and a choice of sound character

USB-connection usually provides power to peripheral devices, and this accessory allows Astin Trew dissolve the desired signal and power to reduce their interference.

When connecting a PC to DAC with it significantly increases the attention to detail on the XLR-output, the sound becomes smoother, more natural bass deeper. With HD-audio difference between the semiconductor and vacuum-tube output levels, and higher quality sound are both options. But, for example, CD-copy of the Rapture of the Deep Deep Purple’s for balanced output we liked more – straightness, roughness and pressure here are just what we needed.

In music, there is no limit to perfection: artists are virtuosos, instruments sound better, sound engineers are building a stunning picture, engineers invent new recording standards and their supporting devices. Xonar Essence One MUSES Edition – about it today and will be discussed – the pinnacle of achievement in the field of Asus DAC with integrated headphone amplifier.

Three versions

The company has three versions of Asus Xonar Essence One. They differ only in the components used (or rather – only op amps) is structurally and color lacquered dragon on the upper face of the body.

There is a basic version of the Essence One. For those who would like to experiment with the change of the operational amplifiers, but can not buy them, made Xonar Essence One Plus – the delivery includes a box with six decent chips Texas Instruments OPA2132PA and National Semiconductor LM4562NA.

Top of the line is the MUSES Edition, a factory-equipped top-end operational amplifiers Muse 01 of Japan’s New Japan Radio Co.

Scope of delivery

The luxury box buyer will find everything you need to start using – the actual DAC, two cable – to connect to an electrical outlet and your computer, as well as an adapter with 6.3 mm jacks on the 3.5 mm headphone plug, drivers, and brief instructions.

Design

Appearance of the device bears little resemblance to the “traditional” Hi-Fi-components. This, of course, not avant-garde in style Chord, but on a curved upper edge of the frame being asked a couple of holes with covers and lamps.

Asus clearly went too far with the amount and brightness of the luminous elements on the front – even in the daytime they distract attention from the music, if you are in sight.

The volume knob looks solid, profitable emphasizing the noble gray color of the metal casing.

Functionality

Asus Xonar Essence One MUSES Edition, as the “little brother” is used to convert digital signals to analog and strengthen them.

Three digital inputs: USB, optical (Toslink) and coaxial (S / PDIF). They are all located on the rear panel of the unit and can be changed manually, the button on the front panel. The result of brute force indicated by an LED in the corresponding text box. Connectors are close to each other, so if you plan to use cables with thick plugs, please make sure that you can connect them.

All-metal housing, it dissipates heat well (when using the device heats up) and at the same time serves as a shield against electromagnetic interference, penetrating the space surrounding us.

Two volume controls. The one on the larger, located in the center of the front panel, is responsible for line-out. Unfortunately, it can not be avoided, as in the Xonar Essence STU. The second regulator for headphones.

For instant mute button is Mute. Why should periodically turn off the sound is clear, but that’s why for this purpose is ill-suited volume control, self-explanatory. One version is as follows: since there is no way to get around the volume control circuit line-out, when working with an integrated amplifier is better to install a handle on the Xonar Essence One to one selected position and did not touch it, and control the playback volume entrust amplifier.

The remote control is not provided, all adjustments are performed manually.

Headphones connected to the jack on the front panel. The amplifier is capable of handling loads up to 600 ohms.

Line outputs are located on the rear panel. Two RCA-connector are quite close to each other, so it is worth repeating a warning about the need to explore the use of cables with thick connectors.

Compared with a younger model, equipment Xonar Essence One is better because there are balanced outputs on XLR-connectors. They allow you to connect powered speakers and get the system without a pre-amplifier, or rather, his role will be played DAC Asus.

Xonar Essence One is capable of handling signals with different sample rates – the list is presented on the front panel LED indicates which is being played at the track. Placement of the series of numbers and LEDs next (and also aligned) with volume control can create a false impression that the user controls the oversampling in its sole discretion. In fact, oversampling is switched on / off a single button, though its non-standard algorithms.

44.1 / 88.2 / 176.4 kHz are converted to 352.8 kHz, while 48/96/192 kHz – 384 kHz to. 8-fold increase in the frequency, regardless of the frequency of the original signal – unlike competing solutions that use fractional odds – should have a positive impact on the quality.

Actually DAC is implemented on a pair of chips PCM1795, included on the balancing scheme, which allows better control of noise. Conversion accuracy and contributes to the 32-bit mode. Other components – to match the class of the device, audiophile quality. In the manufacture of printed circuit boards used to develop Asus – the ground plane, also helps to reduce noise.

The only complaint – physically total fee for all three components – power supplies, digital and analog parts in the equipment of class Hi-Fi and above, many manufacturers are trying to separate them.

The power system is based on the internal toroidal transformer. For the network device connected via a standard three-conductor cable, which makes it easy to experiment with his replacement by audiophile version. Individual contact housing ground there, so you should pay special attention to wiring outlet. In homes where there is no physical ground “vanishing”, “earth” wire can cause background – low hum, well distinguishable by ear.

After you install the ASIO-driver in the system there is a new device, the only required setting – enable ASIO-mode, as a result of information without going through Windows, is transferred via USB to the Xonar Essence One. If done correctly, the front panel LED lights to inform the inclusion of Bit Perfect.

Now, with the computer, you can listen to the recording, digitized to 192 KHz with a bit depth to 24 bit.

The possibility of modifying
Asus Xonar Essence One MUSES Edition can be modified without loss of the manufacturer’s warranty in two complementary ways.

The first – to play with power cords. No matter what the fans of the university physics, the difference in sound is, although not as significant as the second method – the replacement of the operational amplifiers. For MUSES Edition it is not the most relevant, as already mentioned, the device at the factory is staffed by top-end op-amp, and for the Xonar Essence One – completely.

Sound Quality

To assess the quality of sound methods were used, components and items listed in the material of the Xonar Essence STU.

Asus Xonar Essence One MUSES Edition though not without difficulty, but replays CD-player Cyrus CD6 – affect and age, and price category.

The main difference – the best drawing of the scene (although the position of performers a little more blurred). Xonar Essence One makes it wider.

The disc of Tom Waits Swordfishtrombones shows details that previously had to guess: acoustic bass in the Soldier’s Things chamber finds warmth, keeping the articulation.

Audio file release of Patricia Barber Café Blue a lot of fun. Melancholic style of performance, acoustic instruments. And Xonar vividly paints a picture of a small stage on which play your favorite music by professional musicians.

With Mein Teil Rammstein Asus Xonar Essence One MUSES Edition cope easily. Recorded drive there, no cacophony in which it can turn on a system with a lack of detail and dynamics.

Oversampling left a mixed impression. On the one hand is great that it is, and well implemented. On the other – the sound is obtained by “embellished” and “licked”. This may sound very impress at first listen, but like it is not everything. Oversampling is responsible for a separate DSP-chip from Analog Devices ADSP-21261 (from the family of Sharc).

A significant difference between the inputs is not seen, but the optical and coax a little bit better. Perhaps the difference is that used the supplied USB-cable and a simple laptop.

Working with the estimated low-impedance headphones (38 ohms), the Monitor Audio-technica ATH-M50RD (Limited Edition). In principle, Essence One MUSES Edition can discover their dignity better with more expensive headphones, but even this was a worthy companion.

“Toccata and Fugue in D Minor BWV 565” by JS Bach sounded surprisingly natural. This is undoubtedly a collective achievement and a sound engineer, no body had turned into stereoattraktsion and Xonar, which provided a sufficient level of dynamics.

“Requiem” by Mozart – the sublime and sad music. Like all classics, it is played solely on acoustic instruments and strings – a real test for the audio system. Decca Record 1976 filofonicheskaya rather than audiophile, reading the works of well-known conductor Herbert Von Karajan is interesting in itself.

Yes, Asus Xonar Essence One MUSES Edition – plays perfectly. Detailed sound, but without the sharpness, dynamic, but does not cause fatigue during extended listening. Music is a lot of fun.

The device is certainly qualitatively made, and even some design refinements can be forgiven for his musicality.

However, Asus, it should be understood that for the similar (well, a little big) money can buy a device with similar except (a little better) sound quality and functionality also known audiobrenda magic.

IAG Corporation has decided to resurrect some half-forgotten brand EKCO (see sidebar). EKCO EV55DP producer named digital player that characterizes it rather than just a CD-player, as a class, which is rapidly moving into the category of niche products. Today the forefront nominated DAC.

Note the toggle switches instead of the usual buttons – they do not switch, as usual, from one position to another, and by sending a command pulse, bounce into position

Such an apparatus is EKCO EV55DP, brings together the past with the future. In addition to the CD-transport he has two coaxial inputs and USB-port with support for up to 24 bit/192 kHz, allowing the use of its built-in DAC to work with third-party sources, including a PC.

There are a few nice options: two RCA-outputs on the rear panel – one for the analog signal with a fixed level, the other controlled (remote control only), there are also a digital optical and coaxial outputs, allowing to use and EKCO EV55DP as USB-SPDIF -converter, front we see a 6.3-millimeter headphone output, as well as the lamp ECC82 (12AU7) in the box – it is decorated not only components, but also a sound that can be sent and passed her on the path of transistor. Not so conspicuous Available sampling rate converter kGts/192 176 kHz (adjustable by remote control as well as his passing.)

All of these advanced features are packed into a stylish and solid retrokorpus, the design of which must have been inspired by the views of tube radio EKCO 40s. Thick side plates are made of solid wood and lacquered.

Residually

Listening EKCO EV55DP we started with a favorite CD from our collection. Because just playing discs are nothing new, but really high quality is more and more expensive, then rank the sound of this unit is quite difficult – very great his equipment. Let’s just say, play CD – not the strongest side of it, if you take into account the full price of the machine, and no estimate of its contribution from this feature. Character of the sound it is not too collected and refined, for example, in the compositions of CD After Fajr Ahmad Jamal piano very much highlighted and not entirely consistent with the other instruments, although the overall sound rich and assertive. With a symphony orchestra fared worse – the detail is clearly not up to par.

In the starring

But how DAC EV55DP acts much better: it converts the digital stream with excellent transport SACD-player Esoteric X-03 in excellent sound – smooth, detailed, balanced, intense, rhythmic and natural. The same jazz A. Jamal gets its usual form. Vocal A. Netrebko (CD Opera Arias) – articulate, rich nuances, strong. The orchestral accompaniment – designed, as well as lush and big. Turning the lamp attached to the voice of the singer even more colors, in this case already seems redundant.

In non-oversampling – sounding more straightforward and lean, we really liked the version with a frequency of 192 kHz – so performance is richer, fuller and more expressive. Although such a complex music, such as ballet suite Prokofiev’s “Romeo and Juliet”, where accuracy is important, the transformation to the initial frequency of 44.1 kHz was preferable.

Connecting digital player directly to the power amplifier through an adjustable output also gives a little lean, but a detailed and coherent sound, which, if desired, can be given a flowery with a lamp or resampling. In a system with active speakers this function is difficult to overestimate.

The reader has probably already tired of the descriptions of the use of this device, but we just picked up, perhaps the most relevant – from the PC via USB-port. So, happy to report that in this case it is high. Compared with the playback SPDIF-flow from one of the best in the world of transports (which are unlikely to have each hand) the signal from the PC sounds only slightly less detail and work; balance and agility remain at a high level, the sound is smooth and natural, pleasing to the hearing. Above it can also be more work available to a EV55DP means. But a much better result you will get with HD-audio files – they pick up the sound of a step up.

Endowed retrovneshnostyu EKCO EV55DP showed himself a modern station wagon with a mass of useful functions. He offered a couple of tube integrated amplifier EKCO EV55SE, with which we are acquainted, but taken in isolation, the unit will find its rightful place in the existing system, or even become its center (PC or active speakers, for example). So reincarnation EKCO brand can be considered valid.

Nostalgia

EKCO – this is the famous British brand with a long history. E.K.Cole Company Limited in 1926 created a talented engineer Erik Cole and registered trademark EKCO. It produced many kinds of products, including radio and television, as well as a long list of radio and electrical devices.
