The Bryston "b3" series is a very refined and high resolution amp, but it is very fast and can come across as thing/bright in some systems. It can be tamed using a Isoclean gold-plated fuse (internal) and using gold-plated terminations on copper interconnects/speaker wire. I would also recommend pairing the Bryston with a warmer/fuller sounding preamp. I don't have personal experience with C52, but the few youtube videos I listened to seem to indicate the C52 is a very high resolution and resolving amp (not warm or laid back like typical McIntosh gear).
