I'm just getting started putting together my first HT system and will be buying my book shelf speakers and receiver first. I want to spend around $1500 for my speakers. My room is 13' by 21'. I watch 50% tv, 35% DVD, and 15% music. I've tested a few speakers (B&W, Def Tech, Mirage Omnipolar) and so far like the sound of the B&W 600 series speakers best (DM601/LCR60/ASW600). Should I stay with the same speaker for the front and rear (DM601)or can I move down a step for the rear (DM600) and still get good sound? The salesman's recommendation was to stay with the same speakers front and rear. They didn't have the DM600 speakers on the floor so I couldn't hear for myself. Are there any other speakers in my price range I should look at? I've heard good things about the Totem Dreamcatcher but they're not available locally.
