Yep, I've gone through a few rounds of "bookshelf + sub" for music listening and never quite seem to be happy with them - I keep coming back to full range speakers. Downside is that the M60s from my HT system are now sitting down in the living room music system again and everything is the wrong colour again.

I know I need knotty pine M100s, but I'm resisting as long as I can. But maybe not past Aug 31.
