Recevied the USB isolator today and it appears to eliminate the problem completely!

I guess that confirms the problem was ground-loop related..?

Yeah, that sort of confirm it is ground loop. Anyway, good to know it is fixed.

Be careful though, because you will probably get the same noisy surprise if you accidentally touch this amp's case with any other grounded object.
