Looking for a new Amp or Preamp? If you're after tubes, post over here.

RE: Definitely...

Perhaps Class D is a good match mostly on Maggies. ;-)

I heard a pair of Acoustic Imagery Atsah Class D monoblocks (NCore 1200 $9K/pr) at a friend's house driving a pair of Maggie 1.7s and then the 3.7s after he upgraded to the larger speakers. It was a wonderful sounding system.

I tried a pair of NCore 400 monos in my setup as well and a couple ICEpower based amps, and the Hypex UcD 'hybrid Class D' Medusa by Rogue. I ran them on my Thiel CS2.4 -as well as- my Tannoy Definition D500's. Very different speakers. I just couldn't enjoy the Class D amps for very long on either speaker.

Someone posted that tube guys are just expecting that 'bloom' or other 'coloration' and not used to the transparency and accuracy of Class D. That is not the case here. As much as I prefer tubes, I have also enjoyed good solid-state amplification long-term in my setup but I can't seem to warm up to Class D.

I'd rank these amps as significantly better than the Class D amps I have experienced in my system:

- Ayre AX-7e integrated
- Pass Labs 150.5
- Ampzilla 2000 2nd Edition
- Krell KSA-50S

- Rogue Stereo 90 Super Magnum
- Rogue Cronus Magnum Integrated
- Manley Neo-Classic 250
- AES/Cary SixPac monos

These are the Class D amps I have had 'in my system':

- NCore 400 monos
- W4S SX-500 ICEpower monos
- Bel Canto M300 ICEpower monos
- PS Audio HCA-2
- Rogue Medusa 'hybrid Hypex UcD'

and a few other Class D but those were not 'in my system at home'.
