If you remember Fi magazine, they reviewed a system consisting of the Audio Research CA-50 with the ML Aerius i. I own an ARC myself and have very successfully run a pair of ML Aerius with it. My room is 11 x19 x 7. I am not sure if they would have worked as well in a larger room but in my room they sounded great together. I no longer have the ML's but the ARC is driving my Vandersteen 2CE's very well.
