The DC filter not suitable for BOX X5
Periodically, I used to experience a light buzzing sound with my xduoo xd05 pro when using my linear power supply. I don’t have no clue why it emits but when I physically touch it with my finger, it goes away. Well I don’t have time for that. I bought this and no buzz whatsoever. In fact, it sounds clearer and much better. Not sure if it’s placebo but I don’t think so. Buy it!!!!
One after connecting smell burnt.
Very unhappy and that dangerous...
I use it with ZA3. I measured what effect this product has. The second photo is without it, the noise is 180mVpp. The first photo is with it, the noise went down to 80mVpp.
In my environment, I was able to reduce noise by more than half. I think this is a very cost-effective product.
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.
