Fosi Audio DC Power Filter Eliminates High-Frequency Noise

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.

Excellent terrific effect...great value for the money

I ordered these after seeing talk of them in an online forum, some amps had some higher frequency noise with certain power supplies and others said this resolved the problem. My setup is two za3 with the 48v power supply and i noticed a slight high frequency noise, crackle before adding these .. after putting these on the system the noise was gone, very happy to clean up my audio with these!
