Also, and this may be a clue, I noticed REL subwoofer phase had to be changed. As for the phase of the speakers, I thought I carefully wired the speakers keeping red, black & directionality in mind. Phase is just that, correct? Sounds to you like I may have missed something?Maybe out of phase? I've had no such problems with LessLoss speaker cable, even straight out of the box. True they go from OK to muddy, to bright etc but after about 48 hrs they are fine.
