Oddly enough, however, there is a speaker for $600 per pair that is, IMO, possibly better than the Imagine B and WAY better than the CM1.
The Definitive Technology Studio Monitor 55 (which happens to be almost exactly the same size as the Imagine B), is absolutely excellent, and for its price seems almost incredible.
With your advise, I went ahead and listened to them today, and was able to hear the CM1's once again next to the Monitor 55's. Here is what my conclusion was. Please keep in mind that I was running a sub woofer when listening to both pairs and kept the sub woofer on the same settings. I will say that dollar for dollar, you get a real heck of a bang for the buck with the 55's, although they did not have the clarity that the CM 1's had. The 55's at the same volume level where louder and fuller, moderately, although with the volume up slight on the CM 1's to compensate, the CM'1's where the better choice if money was not the priority when comparing the two. The clairity is really nice on the CM1's. The 55's are really pushing it for size limitations that I have.
It is very tough for me to test the CM'1s against the PSB Imagine B's and I would have to travel far to hear the PSB speakers and then i'm not so sure they would have the CM1's to compare with on location. It's tough to make a decision unless I can test two different sets in the same location, with the same song or songs on.
