FWIW, I have recently sent back two, yes TWO, faulty Schiit Freya+ pre-amps.
This has nothing to do with your issue other than there possibly being some over-arching quality issues.
I know folks love the Freya and Freya+, and the passive and SS buffer sounded nice, but the tube section was faulty in both units I received. I tried multiple tubes from known good units to eliminate the tubes from being the problem. One had severe noise issues during playback, the second only hummed before releasing the magic smoke in about 10-20 seconds.
Good luck. You will probably have to send it in for service. I wouldn't admit to the "static discharge". Probably outside of a warranty claim (Act of God , abuse, etc.).
