Mutec MC-3+ USB

[nicoludio]

@nfnc, besides the AES/EBU there are also S/PDIF outputs (coax, bnc, toslink) on the Mutec. I've sold the Intona last week. I tried it (after I got it back with the latest firmware) before the Mutec, but I couldn't hear a difference, positive or negative, in my system.

Thanks, Antoine.  Perhaps I should have clarified that, with the Mutec, there is no option to use a USB output. Therefore, as you have said in post #67 above, it would be hard to isolate whether the improvements are due to the Mutec itself or the use of the AES output. 

The other possibility is that, since AES is synchronous and USB is asynchronous, the Mutec clock is better than the Devialet's internal clock.

That you did not hear a difference with the Intona could mean, hypothetically, that the Mutec is doing as good a job as the Intona wrt galvanic isolation.  From that perspective, at least with the Mutec, the Intona would have no audible impact.

Guess what we will never know is whether, in a pure USB system (USB input/USB output), the Intona is as good as the Mutec (assuming that the Mutec was able to output via USB in the first place).
