The Rubicons are a very impressive range. We've had a few ranges from Dali over the years (Lektor/Ikon/Mentor) but none have really "grabbed" us. The Rubicons did. After those previously held ranges, I was a little dubious when the rep said he'd bring them in for us to try out. I thought it was going to be pointless, and that we'd end up with a wasted afternoon. We tried the 2 standmounts first then the 6 floorstanders. The first thing that struck me was their fast, detailed bass that seemed tighter than any other speaker at this price point (and this was running off a Naim SuperNait2). It had an energy to it that is more reminiscent to that of an active speaker. Nice three dimensional soundstage, clean sound, all helped no doubt to their build quality. Very detailed and open, without any nasties like tizziness you hear with some speakers.
With the 8 at £4k, it made a refreshing change to have a real quality loudspeaker at this sort of price point that didn't need hefty amplification. Whilst they will improve with better amplification, I can imagine them being quite popular for their energetic sound and efficiency, as well as just being a pleasant and rewarding experience. They're not offensive in any way, but they're not laid back and dull either.
