Hi What ever amp you may end up with finally, make sure you listen to a 300B based amps before you decided. I use Cary 300B monos on my Canterburys & get plenty of volume from 96db efficiency for my listening preferences. I have heard 100 watt KT88 vs a 7 watt 300B. Surprisingly they both controlled the speakers equally. Enjoy your great speakers & good luck!
