I think I am going to stay with the CM4s. I really liked how they sounded despite some of the reviews that I read. I like the brighter upper end and the bottom was on par with the DM604s even with one less mid driver.
I actually like the styling of the CM line quite a bit. I have very contemporary tastes.
I did speak with someone at B&W, and they said that they were not discontinuing the line in the US and have no plans to.
I have not heard of Spendor. Where can I get more info?
Anyway, thanks for the input. We'll see how they sound in my room.
