I was about to eliminate the Wavac 833 on the basis that its +9dB bass boost from 80Hz to 160Hz is just too absurd, and reflects engineering far too sloppy, to get involved with -- but then I remembered that the Pendragon ribbon panel exhibits very little load below 200 Hz.
Wavac powering Gryphon 4 Tower speakers I also assume that this model has a crossover at 200HZ. That gets around the bass problem.
