I thought that the AVM60 was cheaper than the MRX1120, It was at least when i bought my unit.

TroyD. You will likely not hear any difference between the MRX1120 and the AVM60 with the MCA50 running your mains. Unless you are driving some massive tower speakers like the M100's in a very large room at loud volumes, you will never be pulling enough amps of power for it to make any difference.

Anthem: AVM60, Fosi DAC-Q5
Axiom: ADA1500, LFR1100 Actiive, QS8, EP500, M3, M3comp, M5
