Looking for a good 5 channel amp to power Axiom M80's. Love the rotel but can't seem to find one used and can't justify spending another 1k on a new amp. Marantz has a pretty good deal going right now but I am wondering if it will handle the 4 ohm load. Any other suggestions in the 750 or less range would be great. This is used for 75% HT, 25% music.
