I would apprreciate some help on selection of an amp for my existing system. I have a pair of Martin Logan Aerius i's, Sony 444ES receiver, NAD C542 CD player and a Pioneer Elite DVD player. I want to use the Sony receiver as a pre-amp for now and upgrade later.
I was looking for a 200W x 5 amp and narrowed it down to :
Outlaw 7500
Sunfire Cinema Grand
Anthem MCA50 (only 180w)

Has anyone compared these amps and have a recommendation? I figure the Sunfire and Anthem will run around $400 more than Outlaw and am not sure if there is any difference in either build quality or sound.
Thanks
