AV123 is a fine company and Mark Schifter takes a lot of pride in the products they produce. He is also always available to talk to if you have questions or concerns.
The Rocket RS250 MKII's are a really nice speaker. The craftsmanship, and finish is second to none. Really good looking speakers.
My short review of the RS250 MKII's is this. These are a very warm speaker. My meaning of warm is, these speakers are more laid back. The tweeter is not bright, or fatiguing to the ear. It is clear, detailed and sounded very natural.
The mids are really full of detail, and the speakers imaging is very nice. After hearing these I would really like to hear the larger Rockets.
The B&W CM1's again are very nice looking speakers. Real wood finishes and excellent quality. IMO I think they really look great with the Kevlar driver.
The CM1's are a bit brighter then the RS250's IMO. The tweeter is really smooth, and without harshness, but is slightly forward of being neutral.
Depth and Imaging are again really good with this speaker. These speakers seem to sound large then their size. I really liked these.
Never auditioned Dynaudio's sry.
With AV123's return policy on the Rockets, I would get both and audition in your home.
