Questioning a/c isolation for digital.?

Isolation does far more than eliminate hum.

Thanks Steve. Well said. Good bye

Steve, I know you're just having a bit of fun, it's ok.

I found that basic conditioning, using chokes and caps, helped inexpensive players with inexpensive switching power supplies to a degree, but just sucked the life out of better built players and DAC's with more advanced power supplies. Using isolation transformers (aka Jon Rich's design) had mixed results but generally followed what I said above.

Now better power cords on the other hand seem to enhance most anything, but after a point it is all about synergy and tuning to your liking.

Ptm. Synergy and tuning, spot on. I do feel exceptionally well executed balanced transformers (for ex. Equitech 2Q) would find a place in every system if they were experimented with. It's just in the fundamental laws of AC electricity.
