My Quicksilver preamp inverts polarity

Switch interconnects? You can reverse the left and right channels thusly, but not the polarity.

Good catch. Oh, brother!

Okay, switching channels vs. switching polarity, mark me as dumb, but why do I "hear" the same affect, or do I?

Actually I agree with you. I am fairly sure channelization has to be consistent throughout the system. Otherwise Sonics suffer. Polarity is a somewhat different animal since for cables it involves switching the + and - of channels, not the channels themselves. I would say they’re separate issues.

Fair point. I’ll make the changes at the speakers when I get home and see/hear what I’ve been missing all this time. Not holding my breathe for a jaw dropping experience but hey you never know....😁
