Integrated for Harbeth Small Room System

I am the new owner of Harbeth P3esr's. My room is 11x12 so picked these speakers because sealed cabinet and they fit and sound great in a small room. My source is computer through Cambridge Audio Dac Magic (for now). Looking for a solid state integrated amp that will pair well with the small but talented Harbeths. Keys great low level listening, take advantage of the harbeth mids, and these little speakers do great 5 inch woofer bass so want to make sure the low end is there.

My budget is $5,000 tops - less would be real good. A variety of music - should sound equally great with Sonny Rollins as it would with Jack White. Some of the contenders I have been thinking about are Luxman integrated, the Sugden 21se, and Ayre AX-7.
