I have the Cornwall III's, I use a new McIntosh MA6600 for the pre-amp section only, driving an older pair of Luxman MB3045 tube monoblocks, 50 watt/ch. The sound is fantastic, although at times I wish I had a little more power.
I found the 200 watts/ch of the MAC was a little too much punch for the horns.
