Should I be reversing one end of my speaker cables? And, are they saying only in active mode, which would mean flipping the cables along with switching from gain to passive?
Well that was a little more than a subtle change. I only had a chance to spin one comp at low levels and could clearly hear a difference.

Hard to explain but it was as if the system took a decongestant. Clearer separation, more air and detail. Looking forward to spinning a few of my reference tracks at higher volume later today.

With this change and some new tubes, I should hit another level of performance I have yet to experience in my system.
