IMO, it is very unlikely you damaged both valves in one day by handling them wrong. They are more durable than you think and a little tap can actually clear up some static issues.
Please clarify what you are saying.... you rotated the valves and now both channels have noise?
If you went from one bad channel to two bad channels after rolling I would hold off installing the OG's in the unlikely event that your Lyr is damaging the valves that were placed in the one socket.
Hence one valve get's corrupted, it is moved to another socket, and the replacement valve get's corrupted. I haven't heard of this happening, but it's electronics and anything can happen.
If Schiit doesn't send you new factory valves, I will. I only use my stock valves for testing.
