Tubes would be a great addition to your system if you'd rather play with it that listen to it! The equipment you have is fine! I've had tubes and I can't imagine what it would take to go back?!?
Now about speakers (that was what your thread was about wasn't it?) Revel makes several fine models. I listened to some of their Studio's last weekend and they sounded great, but for $12,000 they better. Fortunately the technology trickles down. Check out the 20's. The Silverline Sonata's also come around from time to time, used in the range you're looking. If you want to do something completely different try a pair of Mangepan 1.6's. They are a great, inexpensive planer speaker.
My two cents, good luck!
