I'll chime in on the Parasound 2205. I've lived with this amp for several years without a glitch, just make sure you give it plenty of room to breathe or use fans if it will be installed in a cabinet. Gobs of power for music and movies. Warm midrange and good bass slam, it should match up nice with the MA's, as they tend to have plenty of treble energy. At that pricepoint the reliable and proven Parasound amps are tough to beat. If you buy used Parasound will still stand behind the product-EXCELLENT customer service.
