What's the trade in price for the Chord 2qute against the Chord qutest?Mine is less than a year old
Let's get the thread back onto Qutest now please!
If the attached PSU meets USB specifications then you will not void the warranty - I just checked with Matt from Chord about this. I would add that it is designed to be power supply immune - as Hugo 2 is - so i don't expect any improvements from the PSU. But with USB it is easy to connect a portable battery powered USB charger to it - and that for sure would represent the ultimate PSU.
So, when I close my eyes and make a wish what I see is a QTT (Qutest Table Top) or TTQ (Table Top Qute) which would be a TT2 without battery and HP amplification. In other words a 'DAC only' with super capacitors and the improved analogue output stage.
Sure - to a greater or lesser extent. Hence my work on power pulse array - so then we shall all have our cakes and eat them...
So power pulse array allows the benefits of a single DAC amplifier, but instead of the 2W we get with Dave say, I can achieve hundreds of Watts with no loss at all in transparency and refinement - at least that is the intent....
I was under the impression the super capacitors on the HugoTT were essentially to help out the battery on power supply duty, not to beef up the analogue output stage, is this not the case? I can kind of understand how this would help re driving difficult headphones, but if you're just feeding an amp (the likely use for a Qutest) then would super caps be of any use?
One benefit of super-caps is that it lowers the PSU impedance, and hence reduces the distortion crosstalk feed from the PSU. But this problem is eliminated with Hugo 2 and Qutest's PSU arrangement of regulating out from a boost voltage - so now the gain section is fed with clean power, eliminating the distortion that comes through the power rails. Of course, you have the benefit of huge current delivery from super caps - but that is not needed for a DAC.
so i understand....I currently have a Mcintosh 452 amp in my loudspeaker system...if i was to in theory use the qutest in such a system how would i control the volume ?A separate pre-amp along with my laptop as a source?
No - you need the power delivery that supercaps offer for current hungry headphones.
I realise this thanks, and use Audirvana 3 and HQ Player which allow for Native DSD playback (on OS X), which I agree allows for both DoP & Native DSD transmission (Exasound for instance).
The problem, and many others confirm this, is that on a mac, using DoP with the Mojo (and other Chord Dacs), whereas DSD64 plays perfectly, DSD128 & 256 exhibit audio dropouts using this method. This is a significant drawback/flaw in the way the chord DACs receive DSD signals and is something Chord seems to want to ignore rather than focus on in any way.
Notes
a) I have used other DSD Dacs and they have not exhibited this audio drop out problem, so surely it's the way the Mojo or Qutest works with OS X, rather than "the source sending faulty data", which implies it's somehow a problem with my mac or software or files, rather than the Chord Electronics equipment...
b) Will the Qutest receive DSD on a mac natively or via DoP (assuming the DSD will be native DSD either way, rather than a PCM conversion)?
ANSWER - Windows Natively with ASIO driver / Mac DoP it seems ??
c) Exasound have implemented ASIO drivers with OS X (if not iOS), so native DSD transmission from a mac is possible
ANSWER - SILENCE....
The way it was described, it seemed like the following to me:
