All 3 amps won't have problems with 3V nor the 1.5V setting. The latter is just 6dB less loud. Most SS amps (when decently designed) should not colour the sound. (sound like the Tube amps (design dependent) can of course add some 'flavour'. Is Rob Watts selling something by chance ?

he certainly has the chance to sell me a 2qute, a very slim chance with Qutest but no chance at all with Hugo2......... im sorted with my amps Rob! . while i have your attention Frans.... you posted your views, on another thread, regarding the pro's and con's of DS compared to multibit. could you please just give your opinion on where Chord's approach sits? my guess its alongside multibit.

AFAIK the Chord uses DS tech. Other than Schiit (which BTW uses a non-audio MB IC) in some of their DACs and few discrete MB (aka resistor laaders with crappy measured performance well <16bit) 99.9999% of all DACs on sale use some form of DS.

Looking at noise floor plots well beyond 100kHz tells me they use a form of DS (as Javier already mentioned) They don't use of the shelf DAC chips though. Instead they use a very fast FPGA (Programmable Gate Array) and have written their own Delta Sigma kind of thing.
Nothing wrong with DS by the way. The whole Multibit is better discussion is usually done by Vinyl lovers. They seem to hear more than us mere mortals and don't care if it doesn't measure as well. I don't either but am agnostic on DAC chips.
It's not the type of chip that matters ... but how you use it.

The manual mentions DSD256 though I believe the AK4490 it is based on can handle DSD512 so there must be a limitation in the USB receiver and/ot its drivers. As it supports a max PCM sample rate of 768KHz it could point to DoP only support though I find that hard to believe.

its also only a single dac chip from what ive read. as you know the teac ud503 uses 2. is this a big issue , in your opinion?

Dual mono usually brings a 3dB better SNR, a better stereo separation and higher current output. It is objectively and measurably better but certainly not audibly better.

After some additional reading it looks like the ADI-2 Pro uses 2 x AK4490 chips so I think there is a big chance the ADI-2 DAC will use the same configuration. It is a shame they didn't opt for the newer AK4497 which has better funcionality and performance though maybe it came out one the design was finished and it would have meant delays and higher cost.
