So I am looking to power a pair of Cerwin Vega AT-15's. These speakers have surpassed all expectations and pulls great sound from any amp that can handle their 4 ohm load. With its 102db sensitivity it seemingly sucks power from amps. I've had it hooked up to a few amps but nothing significant. I have only had them hooked up to entry level integrated amps and recievers. I now seek to find a power source that can push these speakers to their fullest. They are in a 22' by 12' room. I would like to spend about $1,000. In my research I've come down to two amps. Mcintosh mc 2205 and the Parasound 2200mkII. These amps both have good reviews for both sound and build quality. I would like to be able to play loud music for long periods of time. The Mac has 200 wpc and a great look. On the other hand the Parasound has about 400 wpc and is usualy cheaper on the used market. Is it worth the extra money for the look and sound of the Mac. Open to other suggestions and preamp options.
