Yeah. My response was made in parallell with yours, not as an addition to it. I was decidedly lazy and didn't go into the details of what was the cause in those cases... Figured one could always look up those threads if neccesary.

BTW, I initially had a MkI with the 2-amp setup - also no problem with wine; but I did (as per the instructions) run a ground wire from the amps grounding point to the ground leads of the RCAs.
