Speakers sound too bright.
I just bought a new pair of Martin Logan 60xti speakers. They are too bright and fatiguing. I would like to avoid returning them. I've tried toeing them in and out. I cant get them further than 1ft away from the wall (back of speaker to wall). I have a about 1-2 hrs of play time on them. Not sure if break in will help settle the upper frequencies down. Any suggestions...?
