After several years of wishful thinking, I finally got a chance to hear the RM40's. I'll simply fast forward to the bottom line -- they were, by far, the best speakers I've ever heard. The detail in the bass was astonishing. In fact, I didn't know it was possible to effortlessly reproduce the level of nuances the RM40 revealed in the bass. Likewise, the clarity and detail of all of the instruments was the best I've heard. And, of course, just based on the sheer size of the speakers, I expected a huge soundstage and that's what I experienced. In addition, the RM40's provided extraordinarily natural vocals and a tremendous dynamic range. I want these speakers, dammit!
