I recently sold a more expensive pair of speakers and subwoofer for the 5's. I auditioned many speakers and the 5's outperformed all of them regardless of price. I never realized how inarticulate the bass is in most speakers until I heard the 5's tuned for my room. I run them with Audio Valve Eklipse preamp and Challenger 115 monoblocks(I substituted EL-34s for 6550s so the wattage drops from 140) and Cardas Golden Reference throughout. I had to wait several months to get them which should tell you something about their popularity. They play music.
