Thanks for all the kind words/mentions guys. 
I won't bother to repeat what other have said about tubes and Merlin being a great combo (esp. Joule and Ars Sonum, though I may be a bit biased when it comes to that gear
).
Surprised no one has mentioned Dave Belles's (Power Modules) Aria Integrated amp... for someone who wants solid state on their TSMs this is a great combo. If on a tight budget, a used Rega Brio (one of the later versions) would make a really nice match for a older/early pair of TSMs.
I just had the latest Ars Sonum (Universum series XP version) Filarmonia playing on my BM TSM's a few days ago. Right now the same amp is finishing its break in on a pair of Black Magic VSM with the same amp. Amazing what a really good 30W of tube power will/can do!
Cheers! - Rich
