You really havn't heard what your amps can do 'till you try them with horns. The Klipsch speakers can be found, and are a cheap way to try high efficiency speakers. If you don't mind a slightly (really less than you might think) colored midrange, the Heresys or Cornwalls are great. Less colored (due to the tractrix midrange,) but slightly lower quality (ceramic magnets, cheaper crossovers) are the Forte II, and Chorus II. Bass and dynamics with these systems are way better than direct radiators, which to me all sound thick and slow by comparison. Least ye think me out of touch, know that as a classical musician I hear live music much more than I hear canned. Just an idea.
