The AVR300's amps are very good sounding. If you try the set-up as you explained above, then compare it to the AVR300's internal amps. You may find yourself selling the McCormack and using only the AVR300. I speak from experience. I thoroughly enjoy my AVR300.
Hybrid system with separates vs. receiver
Currently I have a McCormack DNA 1 amplifier and the McCormack TLC 1 passive preamp. I am thinking about buying the Arcam Avr300 for surround sound, while keeping the McCormack for dedicated 2 channel listening. Using the preamp as a pass through, I will have the McCormack power the fronts and sub and the Arcam power up the rears and center channel. Is this a good approach? Or do you think the receiver should power the whole system? I only have one room for theatre/stereo.
