What is an AV grade switching power supply?


Received an AV grade switching power supply wall wart with a network switch and wondered if this is any good. Is a linear supply better. Heard switching power supply's are noisy.

Most cheap, poorly designed SMPSs are noisy.

ifi audio makes a series of high quality SMPSs at several price points.

Here's an example: iFi audio iPowerX

Buy these at Amazon. If you don't hear an improvement, return it.
