I have heard all three of their speakers: Towers, 1.5 and 3.0. My opinion follows: Towers - would not consider buying these...well made but not as impressive as the 1.5 or 3.0; 1.5 very nice, transparent, but a little thin in the low range; especially compared to the 3.0...these are truly remarkable, though a bit on the expensive side. While listening to the 3.0, someone walked into the listening room which had all 3 speakers in various places on a raised stage, and could not identify which speakers were playing... it was the 3.0! Talk about simply disappearing from the soundstage!
