Schitt freya preamp hum- how do I get rid of this?

With regard to Freya build quality, that's a superb piece of gear. I've been inside it and in my humble opinion it is very well made and perhaps even better designed.  

   I agree!

Dont take this wrong way guys, but none of us are any better than the best we have heard or have seen. So if you compare a Schiit Freya against a better sounding unit and design, you are not nearly as impressed. I stopped looking for giant killer products years ago but they simply dont exist. I also learned long ago that I am simply not capable of differentiating a poorly made from a well made product and then applying this build quality to sonic performance.

I own an original version Freya and it's dead quiet, even with horn speakers in the tube mode. Lucky me.
