I totally agree with the McCormack amp suggestions. The place to introduce tubes, in my opinion and if you are so inclined, would be at the preamp level.
I have been very satisfied with VAC preamps in that regard. You can pick up a used Standard LE on Agon for about $2K or so and it is an excellent intro to tubes (plus it is built to last forever). I have also discovered a great synergy between VAC and McCormack gear.
