this is in response to fotopress . He claims that no tube amp can drive your speakers properly. I am quite sure that a large VTL,AR or CJ would beat hands down ANY 100 watt transistor amp.Now to facts.I am driving electrostatic Acoustat 2+2 with a custom built tube amp(full triode parallel single ended class A 60 watt)to measured levels of 105db peaks without clipping or distortion.My room is comparatively large(12X20 feet).The sinus wave is perfect(measured on the speaker terminals)at all listening levels and with all kinds of music.Measurements are very good even with Sonus Faber electa amator loudspeakers.Hopefully,in about three weeks i will do the same on a friends Martin Logan SL3
how much tube power is needed?
Let's say, for a 86 and a 92 dB efficiency speaker. SE triode fans say 10 W is enough, 20 W is more than you need. They use horns and high-efficiency speakers (> 92 dB sensibility). They say high-powered designs do not sound good at low volumes while driving high-efficiency speakers. Others (mainly push-pull fans) say that even though you have high-sensitivity speakers, the more watts, the better dynamic resolution. I don't want to launch a SE/PP war now. This is not meant to be a pure technical question, it also concerns musical taste. What is your experience with these?
