I've been on the hunt for the same. Have Merlin TSM-MXE, Von Schweikert Unifield One, and 47 labs 4722 here now. All three are different and all are good in their own way. If I had to choose a best today, it would probably be the Unifields. They are each in a separate price category though, so what is the best value? I don't know.
What amp are you using?
