- Noise suppression: Through the combination of filter capacitors and inductors, the power filter effectively suppresses conducted and radiated interference, reducing the impact of electromagnetic interference on devices.
- Power purification: Filters out high-frequency noise and harmonics from the power supply, providing a stable and clean power signal, and enhancing the performance of audio and video equipment.
- Device protection: Reduces the impact of power surges and spikes on devices, extending their lifespan.
Used this on a Douk A5 with 32V power supply. There was some low level high pitched noise coming through my speakers with the amp at maximum gain, this filter cleaned it up completely.
I have several Fosi amps and they are all nice and quiet as-is, so Fosi’s supplies must be better.
I still get tons of EMI/RFI interference from my Fosi amp.
It’s not a big investment and so I gave it a try. I’ll keep them. I bought two. For each device because I listen with two monos ZA3. Music coming from ZD3 with op amp Burson v7 vivid.
Alles gut und schnell
These are often overlooked and are pretty good filters for low voltage audio equipment. The only knock I have against them is that the cable provided is not audio quality and actually causes bloating in the lower bass and a very noticeable rol loff on the higher end. Pair it with some after market options out there though and it really is a very cost effective solution that will improve the audio quality of low voltage DAC, Amps, etc.
