+1 Trivema re the Cary 300 SEI. I run mine with WE 300Bs and the results are wonderful with Klipsch Belles, which I sold last year, and Heresy I, Heresy II and Volti Rivals which I still own.

I've never owned anything other than solid state but I am increasingly intrigued with tubes. Thinking of "investing" $5K or so in an all-tube integrated to (at least initially) drive my Klipsch Heresys. Any thoughts on these two choices? Is there another choice in this range?
