High End Audio Repair

It's a Pass XP-20.

I'm in the UK so have already sent an email but their site states they have a spam filter so if they don't reply within an acceptable time then call. 

They also state they're official repairers of many manufacturers including Pass.

That would be great, thank you. Incoming PM...

Thanks Bob.

I inquired about using HEAR because they're in NY & much closer than CA.
I emailed Select Audio at the same time as HEAR. I've had no reply from Select.
