The Triangle Celius 202 is my current favorite among my many speakers, and it mates well with both tube and ss equipment, in my case I have used them with Krell 300i as well as AR SP9-II and VT-60 with the Krell assisting its bass performance a bit more. The bass can be beaten by a lot of other good speakers, but it is hard to better in terms of total musicality. I have no experience with the Studio 100's and cannot comment on a direct comparison.
