AntuanMark Could you please compare sound with and without an isolator?
As luck would have it, last week I tried out a different wall wort to see/hear if it made a difference.
Yes it did. It fried the isolator . In my haste I did not note that the plug has the +- voltage reversed.
What I can say is, listening without the isolator, since I now have no choice, the sound has a very
mild/fine grittiness and a loss of air and cohesiveness, that is to say the impression that performers
are playing in the same space. A loss of musical flow? For the small cost it's worth a try.
As to the cable problem, at first I was using a compromised cable I had modified to use an
external power supply. Once I swapped in my printer usb cable it worked ok.
UPDATE: This morning ......
I don't understand how or why but after poking around with a meter checking for voltages
which were 5v after the sm-reg, good, then pluging the monitor01usd in and then into the
Buffalo dac, well, it's playing!? Maybe checking the diodes reverse biased them or ??
I will compare the sound with and without the isolator.
