Congrats with some wonderful speakers! I have lived with my 20Ts now in two years and absolutely love them. They definately deserve great gear and some powerful amps!
I have tried (and lived with) the following amps on mye 20Ts in this order:
* Jeff Rowland 501 monos (4 x for biamping) - much power, but too dry sounding, not musical enough for my taste.
* Theta Citadel - incredible amps, very musical, warm sounding, but not the latest word in resolution and dynamics. Still a very good match with the 20Ts. I would pick these over any tube amp for the 20Ts I think.
* Jeff Rowland 301 monos - the amps I have now and by far the best. More neutral and transparent than the Citadels, faster, even better dynamics and bass control and much more resolved. Delivers a huge and seductive sound on my 20Ts.
For fun I have also tried the Cary V12 monos(100watt) on my 20Ts, but that was awful. Too little power! My advice is to stay away from tubes on these speakers unless you go for some megawatt tube amps like the big VTLs or similar.
I have recently stepped up to Burmester reference front end gear (I have the latest 069 cd and 077 pre) and I find that the 20Ts are up to the task. I am amazed! Definately some speakers you can grow with.
I also have a room at size 14 x 18 and have Daad and Auralex acoustic treatments. I have bass set to "0" position and also have a pair of SW12 subs. I use the speaker level input on the SW12s (which is way better than the line level inputs for music). The bass I have is very tight, deep and firm. A guy who works with acoustic treatments visited my and said he was chocked. He had never heard so good sound anywhere in a private home before ...:)
In my experience it is almost always best to toe-in speakers, so also with 20Ts. In this way you also get less side wall issues. I have tried some different angles, but have ended up with toe-in so much that the speakers point directly to a point about 1/2 feet behind my ears.
