Some interesting snippets of information above. Take the above quote. Theoretically it doesn’t make sense for an upstream cable with no feed into the final locally stored stream to affect SQ but according to CKK it does. This is also my experience with my Innuos Statement. Is it because the upgraded cable allows less EMI into the system? I’ve upgraded several upstream remote stream cables and each time heard a useful uptick in performance from locally streamed files.
Re the AQVox question......the PS on the AQVox can be significantly upgraded, despite the manufacturer’s claim to the contrary. I added a Sean Jacobs designed CHC DC3 to an AQVox and the level of improvement was hard to believe, considering all I’d changed was the power supply to a switch. However if you think about it, what comes out of the AQVox is a voltage stream generated from the DC3’s 5 volts, so maybe not so surprising.
Finally regarding the SoTM TXUltra. I also found this to be a downgrade to the Innuos’s USB stream so there’s no doubt its 2 cables, extra PS etc is going to degrade the Extreme’s USB output. In my experience a good USB cable (in my case a Synergistic Research) gave me the best SQ
