A bit off-topic, but I had a chance to listen to Chord's new Dave DAC at a launch event last week (they also launched Mojo, essentially the Hugo electronics in a package the size of a pack of cards). There was also a short presentation by Rob Watt, the independent designer Chord use for their digital devices. Dave is using a 28nm Xilinx FPHA that gives RW 166 DSP cores with which to do interpolation, filtering, etc. Alas, I don't have any copies of the slides, but I do remember that 17th order noise shaping was used and there was a very interesting configuration on the output amp that I hadn't seen before. RW is in the "it's most important to get the transient timing right", also following the path other UK manufacturers hold to which is that the ear can discern timing differences equivalent to 250khz sampling rates, and it's this that's important, more so than frequency range. He has also produced a device (approx $13,000 BTW) that has some of the lowest noise figures I've ever seen, with a basic device noise floor down at -150 db and an extremely clean-looking -127db A weighted result with a 1 kHz signal at 2.5 v output. RW was adamant that removing music modulations appearing in the sound floor is crucial as it's this that greatly contributes to opening up a 3D level of imaging. RW is also working on an A to D box for Chord that runs at 768khz and so Dave also offers that sampling rate too, the hope being that, a bit like MQA, there's the chance of really pulling together the entire recording-to-reproduction chain, offering the listener a chance to hear what the performer (or recording engineer, at least!) really wanted to have conveyed.
Sound? The most impressive thing was a) sound staging, b) detail retrieval, and c) image depth. On every recording (even the bad ones), you could hear deep into the acoustic space it was recorded in, be it live or studio. Instruments set back on a stage in, say, a classical concert, really were set back there! The system also extracted detail I'd previously missed in tracks that I thought I knew extremely well, and did so with 44.1k RBCD.
I've heard quite a few very high end systems over the years (and this was paired by Chord amps and Estelon speakers, call it $100k total) but have never heard a sound stage quite like it. Now, this was one incredibly revealing system, perhaps more than was comfortable at times. However, I would say that I've never really gelled with the big Chord amps and would love to hear the same set up but with something different in the middle. The Estelon XAs are neutral and fast, but the amps just seem to squeeze the color out of some tracks, which for me is a bit too much of a trade off in return for huge reserves of power.
as it has the analogue volume control from the CPA5000 pre-amp. I bought it and sold the QBD76/CPA4000 saving a box and improving the sound. And it has a headphone out...
