I've heard some nice Class D amps at shows which were $4K to $10K. I just read a review at SoundStageUltra.com of the Merrill Audio 118, $36K Class D amps versus Mac 1.25KW $25K amps. My best friend uses Channel Islands Class D amps for his difficult to drive speakers as that's what he can afford. I own all tube equipment but for my new $5K DAC which is superior to my 15 year old tube DAC.
@stereo5 I don't know about the early VS speakers but I've heard three of the top VS speakers over the last 5 years at shows and they are the best sounding speakers I've ever heard. So many people enjoy the VS 33s that I suspect your system was not synergistically compatible. I had a compatibility problem with an EAR 890 with my big speakers 15 years ago (6 12" low impedance woofers didn't mesh with the amp but works great with my 2nd system speakers with 6 10" higher impedance woofers).
