Hi to anyone .
I have a D50S connected to my desktop computer via usb and to my speaker via rca (focal alpha evo active speakers) .
The problem is I have a lot of noise coming from the pc .
Most of it was ground loop so I tried my luck with usb isolator ( ifi one from a friend ) .
Ifi defender solved the noises coming from moving the mouse or GPU working and most of the harsh sounds(I guess ground loop noises).
But introduced a very high pitched and very noticeable "ZZZZZZ" that is so pronounced and I can hear it through songs .
If I remove IFI isolator the buzz and hum comes back but the high pitched "ZZZZ" goes away.
The IFI isolator is not faulty because in my friends setup it works very well without any issues.
Also d50s is not the fault because If I connect the d50s to a work laptop or my phone through usb I don't any noise as all .
The computer and dac power supply come from the same power strip (because i read most of the thread in here )
Any cheap solution that will work so I can use my desktop computer for listening to music ?
