Bostonjim - Congrats on the CATs. One of my 3 favorite systems at CES this year used a pair of CAT Monoblocks (along with a Reimyo CD player, forget what pre and Ascendo speakers). Rock solid bass, clean natural midrange, powerful and engaging sound. Beautiful to look at, too, with all those big tubes in the open.
Mrtennis - I remember you once posted that you like dull, boring sound (or similar words). Have you ever heard tube amps by AtmaSphere, JJ, or CAT? I suspect you would not like any of these, as they are rather lively and engaging sounding. On the other hand, you might prefer the sound of old Hafler solid state, as I remember, it had a definite laid-back quality. Hovland's solid state has a very easy-to-listen-to quality, which you also might find appealing. Perhaps there is one aspect of sound that you are focusing on that is more prevalent among solid state than tube gear. If that one trait is the most important thing to you, I understand your point, but I have not found such a distinguishing trait that universally identifies ss vs. tube.
