I used a VPI frequency generator on my VPI for many years and I believe it to have been a sonic improvement even though my power was very stable. My very best experiences with audio have never come with an eye to reducing cost or saving money. Nothing wrong with that, but $1,200 to enhance the sound with technology often proved is not the path to great sound.
Some of the best sound I have heard Is battery generated.. audio circuits most common… my Aurender Streamer now, I would be pretty unhesitatingly ing trying a battery source. You have occasionally leap to verify you have tried.
