The cat must die! Seriously, if you have no other resort, you can attempt to remove the affected/effected(?) boards. They can be washed in electronic curcuit board cleaner fluid, the same stuff that they are washed with at the factory. I just can't think of the name of the stuff. Good luck.
I have BP20's on an ADCOM 555. Awesome! My HT setup is BP20 fronts, CLR2000 center, BP2X surround on a Sony DA3. Not too bad, but doesn't compare to the ADCOM. Have fun! Don
I have a DA3 and you have full control on every channel, including increasing or attenuating each channel. I think by either +/-10db max or +/-12db in 1db steps.
