Fosi Audio DC Power Filter Eliminates High-Frequency Noise

It works ,music became more detailed

I bought 4 Fosi V3 Mono's with the 48V/10A Power Supplies to Bi-Amp my Wharfedale Denton 85's. I had read about "hum" issues with the power supplies, so when the DC Power Filters came out at $20 each, I bought 1 for each amp. While I hadn't had any problems, they seem to make the amps run with an (admittedly subjective) even quieter background. Definitely worth the $80 for me.

They have not shown up yet I’d love to test them

I was running my V3 monos with two 5 amp supplies till I received the power filter. I then used the splitter cable with the 10 amp supply with no problems. It didn’t seem right to have two mono amplifiers sharing one power supply. I ordered another 10 amp supply with another power filter. It came with a real short power cable and the original supply only came with the splitter cable. New longer cables were acquired and everything is working fine.
