Best Integrated for JM Labs Micro Utopia BE

Downsizing and starting fresh. All the big boxes, wires, conditioners and cables going downstairs to the new dedicated theater/listening room. Wife loves me now. Going back to the simple life with a new pair of JM Micro's and an Esoteric Uni-player. What is the best integrated to drive these little guys? My dealer is suggesting a JR Concerto, but is that too much amp given their efficiency?

Thanks in advance!
