Rrm - in my listening tests I never found the 22L2's to be bright. Music was Monolake (electronic), Heartless Bastards (garage rock), Black Keys, Dire Straits and of course Bowie. Some Bowie tracks tend to ring on my home systems, but they both feature metal dome tweeters, the 22L2's have soft dome tweeters - this could have caused some slight reduction in harshness.
One of the testing rooms was at a dealer here in Denver. He had systems on three walls, and shelving on the fourth, but the 22L2's got the best electronics (high end Vincent and Parasound Halo seperates) and some acoustical foam treatment behind the gear and the listener. The other testing room was in a hotel at RMAF, the 22L2's were on a side wall in an alternate system. They still sounded great. They didn't come close to the electrostats on the other wall, tho!
Yeah I've read that 'tech radar' review myself, and I cannot understand how they can give the B&W 683 a 5 star rating, and give the quads only 4. That is NOT the case. And I am not saying that because I'm a B&W hater, My HT system is B&W 6 series and I love it. The Quads are just better. The only speakers that would beat them might be the Focal 836V, but I haven't auditioned those yet. KEF's new Q line is also on my list...
Lots of dealers run speakers costing less than $2000 with home theater receivers. This is NOT the best way to audition speakers for a 2-channel music system. I was lucky to hear the Quads on some really nice 2-channel gear.
Regarding bright speakers - this is why I bought a pre-amp with tone controls - if it gets harsh I tone it back a little. I'm not a purist. I'm into the music!
