<font color='#000000'>HI,
The Thiel's are floor standers, about 80 lbs each. For really good bookshelves, you might check out Axiom- I had been considering the M60's and ordered a pair of the M2i's just to see what the build, sound, and finish were like. I was amazed for about $250. *Extremely* clean sound, pin point on soundstaging, and excellent build quality. The limitations of these are that they only go down to about 70 hz so you've got to have a decent sub to fill in the bottom. Don't let the low price fool you. With their return policy, you only are risking one way shipping.

The current issue has a very good review of the Copland CSA29, which is what piqued my interest. They go into a lot of detail about the tube/solid advantages, but their bottom line is that this particular amp seems to play up the strengths of both type, while minimizing the weaknesses. That is, the warmth, detail, and musicality of the tubes, with the bass and transient attack of the solid state. Like I said, interesting enough to check it out.</font>
