Hi !
thanks for confirming my sensations about the importance of a good quality (i.e. not noisy) psu.
The usb to spdif converter has, among other things, also the duty to set the clock for the dac downstream. The better the power supply to the clock the better its stability i understand.
I remember that in many cd players one common mod was a better regulator stage for the clock circuit.
Unfortunately i do not have a very high quality converter and neither a high resolving system because i would like to verify one point.
I think that if the converter is very high quality, the resulting sound quality should be quite independent from the actual pc used as a source.
Another idea would be to try to test the digital signal out of the converter with some instruments.
But i have no idea how to do it. I think that with the right test signals something could show up.
Maybe there is out there a converter particularly well built and not very expensive.
One of the best instead is The Berkeley Audio Usb alpha.
Thanks again.
Kind regards,
bg
