Decware is a good suggestion...w/the Cornwalls efficiency and sensitivity you don't need a ton of power if you go tubes. I've owned the Cronus Magnum, ARC Vsi55, Cary sli-80 and believe they are overkill powerwise w/cornwalls. Of the 3 I liked the Cary the best by a long shot. I've found that smaller tubes amps w/just enough power sound much better than larger ones. 2 power or output tubes per channel is enough and easier to maintain. A triode stereo tube amp would be a great setup....have fun!
