i heard a pair of the *duo's*, a couple years ago at a small shop - deja vu audio, mclean, va - & they were fantastic! this was the version w/the older subs; still no integration problems. they were being driven by some home-made 1.5wpc set tube amps. not the best room, but still amazing sound. unbelievable detail, but still not fatiguing - i was there for over an hour at lunch - got back to work *way* late!
