oodles of power, can handle 4 ohms without coughing, and puts out gobs of power for brief periods of time into 2 ohms. Very respectable warranty, adequately low distortion, etc. Should be able to drive just about any speaker out there without problems.
well I sold my sunfire signature cinema grand architectural unit on audiogon a few weeks ago. IMHO- just didnt provide enough current as my trusty sherbourn 7/2100. Although the sunfire is rated with more watts, the sherbourn provided much more bass for my speakers. The sherbourn also has better articulation and depth with my speakers. Hope this helps.
