Well, I'm seriously eyeing these speakers for my new setup... I went and demo'd them, they sound quite nice, they are smaller than the 604s I had before, to me, they seemed to have a nice, crisp sound to them, a little tighter than the 604S2. Where exactly do these speakers fit in the current line-up? A go-between for the 600 and CDM NT series? I currently have a Yamaha HTR5280 receiver, I'll eventually get something better, but I can't afford that right now. Will this be good enough to push them? It worked with the 604S2s, but they were really giving it a workout. That's the main reason I didn't re-consider the 604s at this point (or the CDM stuff), and the CM 4 is slimmer and a little shorter than the 604, which is a big plus for my small room. So, just to give an idea, here's what my setup should look like in a little while: B&W CM 4s (main) B&W CM 2s (surround) B&W CMC (center) SVS 25-31PC The CM 4s did lack a little on the very low end, when compared to the 604, but if the SVS is half as musical as everyone says it is, I'll be in good hands. Most of what I listen to isn't that bass-laden, and the crisper highs and mids were more than a fair trade-off. Anyways, just looking for comments or suggestions. I know I've been all over the place, from PSB to Infinity to B&W, but I think I will really fall in love with the combo listed above.
