Are cheap power supplies any good for audio measurements?

Описание к видео Are cheap power supplies any good for audio measurements?

I will review the cheap ($80) Hanmatek HM310 power supply and compare it to the HP 6237B when used to power high-end audio circuits. I show how to measure the load regulation, step response, and readout accuracy. I also compare distortion measurements of a high-end preamp when powered by the two power supplies.
