I have been using a switching power supply with my T-Amp. I got it for 8.00 at my favorite local electronics surplus store owned by a techie type. He advised that at the frequency the power supply switched at, I would not hear any noise out of the T-Amp. And I don't, it sounds good to me. My question is, has anyone had problems using switching power supplies in audio applications? Or is it one of those deals where only my dog could hear it, and she ain't complaining either.
Quote from another audio board:
"Linear" supplies are "traditional", they are largely inefficient but supply
a nice clean supply. "Switching" supplies were invented as a means to more
efficiently generate large currents, but their switching puts high frequency
noise into the supply. Things like computers don't care about this, and so
use high power high efficiency switching PSUs... while of course Audio is
more sensitive to such things, and so people generally stear clear of
switching supplies (at the price of power efficiency!).
