Hey man, I'm having some of the same problems. I am really not impressed with these speakers for music. HT sounds great but music, especially rock, sounds like sh*&. I've run my 8.5's since Sunday and they are still producing questionable quality. After listening in the same room with the volume set to a moderate level I end up with a headache.
I am really trying to love these speakers, especially at $300 but I think I will return them this weekend.
ps...I've worked with speaker placement, sub adjustment, and receiver adjustment and they just are not impressing me.
