Although I have not tried a 45 or 2a3 with the Zu Def 4s, I did try both with my Zu Def 2s and agree with Phil. I eventually found them restrictive and too much of a compromise.
Keithr, I realized quite a while ago that it`s hard to predict what combination of components will sound best to a particular listener.Your Def IV(on paper anyway) is 6 db more sensitive than my Coincident speaker and should mate even better to the lower watt amplifiers. I have a 100 watt (60 watt in triode) and a 40 watt amp(20 watt in triode) both are push-pull circuits.In my system both are bettered by an 8 watt SET.there`s no substitute for hearing amps in your own system. you are right in that YMMV 'strongly'.
Glory, still awaiting elaboration on your leading comment about Def 4s stock footers. What should I be thinking about? Stillpoints? Equarack footers? Wave Kinetics footers etc?
