turbo, have you listened to the Parasound JC 1 monoblocks to compare them to the A21s you were using? Lots of people say the sound is even better.
Yes as matter in fact a really good friend of mine owns a pair and they are wonderful amps to listen to and I do believe they better than A21. But again, different room, different speakers.
This is what I am currently run with my B&W 804 Diamond. Accuphase A-200 x 2 (pure class A mono amp & 132dB SNR)

I also plan to sell my B&W 804D and move to a B&W 800D instead.
Cheers
