I reversed the leads last night and it was clear to me that I lost some bass only, with highs unaffected and mids just undecided. Listened most of today with same conclusion and that the swap was not that dramatic so I just switched everything back to my personal contentment. However, as originally stated the big gain with these loudspeakers and cables was wiring them separately from the 8ohm and 4ohm outputs dual shotgun - rather than my previous bi-wiring and also trying straight shotgun with jumper cables. Ah, now time to pour a whiskey, pull up Diane Schurr and listen to Louisiana Sunday Afternoon and other cuts from her COLLECTION album. Best to all AudioGoner's
