Hi Matt, I don't think it'll show up in a comparison like that because with Audiodiffmaker you're only looking at digital side of things so the 1's and 0's.

As I believe the data transport to be bit-perfect and the cause of differences to lie on the analog level you'd have to measure that part as well with high-end analog measuring equipment. Of course I don't have this type of equipment so I'd have to rely on my ears.

And I don't mean any disrespect by saying this but to be honest I'm not really interested in these type of measurements, if it works and I can hear a positive improvement (whether that's because of my brain through suggestion or my ears doesn't really matter to me) and enjoy the music more then that's enough for me.

Antoine,
That's fair enough, and I certainly don't want to begin some crazy crusade to persuade people to measure every darn thing.
I was assuming it would be possible to use the Devialet's USB output to record a musical signal on to a PC, in the same way as one would use it to digitize vinyl. In which case it should show up the effects of any changes made upstream, of whatever nature. So if, for the sake of argument, you had a hellishly noisy PSU in your NAS, that noise would show up in the recorded file. But maybe that's not the case.
Cheers,
Matt
