I owned an Audio Research GSi 75 a few years ago. It is a fantastic piece with phono and DAC standard on all units. I needed more power as I have Wilson Audio that are a bit power hungry. There is one on USAM now for $6000.

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?
