Since digital playback was in its infancy, the best sound from CDs and subsequently from SACDs has come from playing them over a two-piece system which separates the CD/SACD player into two component parts, the CD/SACD transport which reads the information on the disc and spits it out as data, and the DAC (Digital to Analog Converter) which takes the bit stream and reconstitutes it as a musical waveform. The newest Version of a Transport is the Music Server.
There are several reasons for this: First, two devices means two power supplies which results in greater efficiency in regulation. With two devices, the magnetic field generated by the power supply of one component of the system is far enough away from the other component so as not to engender harmful EMF interaction between them. Finally, two boxes mean more real estate for each piece which can be used to create greater distance/isolation between the power supply of one unit and the sensitive signal passing components of the other.
That being Said, CD/SACD all in one players have come a very long way and these days there are many 1 box Players which out perform comparably priced separates.The best of these have multiple digital inputs into which one can connect A music server and other digital sources.
Sound by Singer pioneered separate digital components back in the mid 80’s and continues to be the home of the very best digital separates and CD/SACD players from renowned companies like MSB Technology,CH precision,Chord Electronics, PS Audio, Bryston, and Luxman.
Chord’s most advanced DAC to date is the DAVE. Frankly, I did not know what to expect when it arrived and even more frankly did not actually much care as I was blessed by an over abundance of nominally similar converters. Then I set it up and played a few Hi Res files through it. It took about 5 minutes for me to realize that DAVE was not only playing rings around competitively priced DACS but was putting components which sold for twice it price to shame. Today , the next step up from DAVE which we offer is 2.5 times its price. That says it all !
DAVE is not just a highly advanced reference-grade DAC. It is also a superb digital preamp and headphone amplifier. British in the tradition of an Alan Turing , DAVE employs a new (and in electronics terms, huge) LX75 version of the Spartan 6 Field Programmable Gate Array (FPGA). The FPGA''s amazing capacity results in significantly improved timing and the best noise-shaper performance of any known DAC. DAVE''s technology delivers music with unparalleled veracity and musicality, with an unrivalled timing response.

“It doesn’t take more than a few seconds of listening to realise that the DAVE is something special. It just sounds so right from the beginning that it genuinely takes effort to even try to deconstruct its performance. When we did, we found a formidable array of talents with no discernable weaknesses. Orff’s Carmina Burana is one of the most demanding pieces of music we know. It has savage dynamics coupled to complex instrumentation and varies from outright frenzy to angelic harmonies in the space of just a few seconds. The DAVE takes it all in stride.
This DAC renders a convincing acoustic – a believable space populated by the choir and instruments. Sound staging is excellent. It is precise, layered and neatly arranged. More than that it’s stable, even when the music turns demanding. The tonal balance is similarly impressive being even-handed and utterly convincing. No part of the frequency range gets undue preference and there’s a lovely balance between attack and refinement.”

Put simply, the Blu MkII upscaling CD transport sets new standards for CD sound quality by using the very latest FPGA technology to implement advanced proprietary filtering and upscaling techniques. Our next-generation CD transport incorporates a powerful new FPGA core with extraordinary capability.
Blu MkII’s sophisticated WTA (Watts Transient Alignment) filtering and upscaling algorithms can output digital data at 705.6kHz (16 x CD’s 44.1kHz native resolution). When partnered with the critically acclaimed DAVE DAC/preamp, with its 705.6kHz-capable digital inputs, the Blu MkII sets a new technical benchmark for CD performance, while redefining sound quality from the medium.
At the heart of the Blu MkII lies an enormously powerful Xilinx FPGA. Rob Watts’ (Chord’s Digital Design Consultant) has used this to create his exclusive WTA M-Scaler technology, which incorporates the most advanced filter of its kind in the world. The Xilinx FPGA has also enabled a key breakthrough in tap-length (the technical indicator of how complex the interpolation filter is) taking Blu MkII to an unprecedented 1,015,808 taps.
A comprehensive suite of high-performance connectivity is offered and the Blu MkII also features a USB digital input, meaning that it can also be used a standalone high-performance upsampler, for use with other digital sources.
Further features include Chord Electronics’ legendary proprietary high-frequency switching power supply and a dedicated CD-only laser mechanism for an uncompromising performance.
“Want to know the best CD player we’ve heard? The answer is depressingly expensive. It’s Chord’s Blu Mk II transport combined with its range topping digital-to-analogue converter, the DAVE. Quality costs - and in this case the price is a hefty £16,000 for the pair.
But regardless of price, we haven’t heard a more insightful or transparent CD playing alternative.
Those who think all CD transports sound the same are in for a shock. The Chord Blu MkII delivers the most informative and enjoyable sound we’ve heard from the CD format. While it’s expensive, there are far pricier alternatives that don’t get close. We’re sorely tempted.”-WHAT* HIFI 22nd November 2017
Qutest is A ‘pure’ DAC (it does not contain headphone amplification or rechargeable batteries like some of its range stablemates) and is designed to improve sound quality in the home. It is the latest evolution of our most affordable standalone DAC, the multi-award-winning 2Qute, which it directly replaces.
Qutest, which is a What Hi-Fi? Star of CES 2018, is based on Chord’s award-winning proprietary FPGA technology developed for the class-leading Hugo 2 DAC/headphone amp, giving it proven class-leading technical and sonic performance.

As John Atkinson,Editor in Chief at Stereophile at the time, commented:
The immediate impression was of extraordinary clarity. This wasn't as if the edges of the objects within the soundstage had been enhanced, as can be done to images with PhotoShop, but as if the pixel count of the image had been increased. It didn't manage this by emphasizing treble detail, but to resort to an audio reviewer cliché, the DAC502 cleaned the window into the recorded soundstage to an impressive extent...
(U)ltimately, musical enjoyment is what this product is all about. As I write this conclusion, I am listening to Stanford's hauntingly engaging song "The Blue Bird," performed by the Gabrieli Consort directed by Paul McCreesh (from Silence & Music, 16/44.1k FLAC, Signum Classics/Tidal). The interplay between the unaccompanied voices, the bell-like interjections of the high soprano, the setting of all the singers within a supportive chapel acoustic—the Weiss DAC502 made all these aspects clear, in service of the music. Which is what a great audio component should do."STEREOPHILE, Jul 24, 2020
The Helios WEISS'S state of the art D/A converter with an unprecedented level of sophistication and versatility. With the Helios we are creating a new paradigm for what used to be a black box device."It's an 8-channel D/A converter with four DACs per channel," the younger Weiss explained. "The housing is fully anodized aluminum. The 502 that Stereophile reviewed also has four channels, but they're split between the speaker feed and the headphone feed. The Helios has four channels on the left and four on the right. What's most significant, however, is the unit's analog stage, whose new discrete operational amplifiers are of the utmost importance." A typical D/A Converter is a ”set and forget” device. Not so with the Helios. It adds a number of interesting signal processing features and sports a variety of digital inputs. Balanced, unbalanced and headphone outputs are provided. Weiss Engineering has a 30 year history in D/A Converter design. In that time span we have learned a thing or two about converter design. The Helios is the essence of our experiences
