Devore Fidelity Super 8's would work great. I heard the Air Tight ATM 300 powering a pair of Merlin TSM's a few years ago, worked well in a small room. I love the Air Tight sound!! Wish I could splurge on the ATM211 or the ATM-3's!!
I currently own both the TSM mme and the Devore Super 8 (but not for long, sold and to be delivered this weekend), but I heard the Coincidents and Silverlines, both Set friendly, but very different sounding than Merlins or Devores.
