I think your MC601 is a much better amp than the pass Labs
Mcintosh mc601 vs Pass Labs XA 100.8
I have a mcintosh mc-601 monoblocks amplifiers, I have a dynaudio c4 confidence speakers and ayon cd5s cdplayer, I want to buy a new amplifier, a Pass Labs XA 100.8 POWER AMPLIFIER is a good options? Is a upgrade in relation to the macs 601?
