I GIVE UP

Need practical advice from practical people, My Martin Logan SL3's are "tear your head off bright". I originally had a parasound line preamp, 2 parasound 125 wpc amps in a horizontal biamp configuration. I was told to try wiring the amps either mono or vertical biamp, try different interconnects, try different speaker cables, and try a different preamp. Well, I spent quite a bit of money and sonically, believe me when I say, there was absolutely no differnce at all. I'm certain, no ear could hear even the slightest differences. I'm not getting into the brands of cables I tried, i'm convinced solving real problems with cables is just BS. I went from the parasound pre to an EAD encore. I have been able to fix the problem, and make my system sound absolutely amazing. The problem is my wife cant deal with the blankets draped over the Martin Logans in our living room. Please help and give real advice. I'm considering giving up on ESL's, however there are many sonic advantages, that I really like about them. Please dont even bother with any ideas about positioning them, they have been everywhere except in the basement.

Thanks, Steve
