I have CI D200 amps (five of them) which replaced CarverPro ZR1600 amps (three of them) in my multichannel system. The D200 amps are fine-sounding, and not too expensive. However, I don't think that they are significantly (if at all) better than the ZR1600s, which produce more power at half the cost. All this driving Maggie 1.6 speakers. Neither amp generates heat.
