Axiom Home Page Forums General Discussion Technical Questions Need quick input about amps, interconnects and SQ

It sounds like it is not so much as fatigue but you are just demanding too much from the Denon. I would also consider running a seperate amp for your Zone 2 as well, or insted of, a seperate for the mains. You just feed it from the low level outputs from the Denon, this might help in the noticeable drop in volume/power you noticed fom the Denon. This amp wouldn't have to be as huge/expensive as the one you will need to run the M80s on to get noticeably louder.
