Dear CCHP, the newer 700cx and 750cx Krell amps are using some of the technology found in the Master Reference and I wonder if you could get near the quality at a fraction of the cost of the Master? It's worth a listen. I've owned the 600C and now the 650's and I have been very pleased with the sound and performance. I also have the KPS-25sc and was humored by the "harsh" Krell digital comment. Until the Meitner DAC 6 I recently heard at the Home Theater show in San Francisco, the Krell was the best I've listened to. Good luck.
