I’m running with Merlin TSM Black Magic Edition in a second system powered by the Ars Sonum Filarmonia, and they sound great. This is my second pair as I foolishly sold the originals. I’ve also owned the floor standers with master BAM but prefer the versatility of the TSM. Add a small sub or two and it’s a fantastic and fun little system that punches with the big boys.
I also like the smaller ProAcs having heard them with Synthesis amps at Dejavu Audio near DC, and in their room at Capital Audiofest. I liked the ProAc / Synthesis pairing so much that I run the Titan A100 KT66 integrated amp in my main rig with ProAc D40R.
You can’t go far wrong with ProAc or Merlin.
