Post Subject: If less is morePosted by Paul S on: 7/14/2007
then the idea of amp bypassing is relevant to the "clean signal" discussion. But regardless of the measured voltage out vs. driver sensitivity I suspect that there is too little of something in the way of drive and control between a 2-3 octave compression driver and a pre-amp, let alone a phono stage or CD player with resistors and a unity buffer between the source and the driver. It remains to be seen/heard how much or how little power would really be needed if the circuit were optimized for the driver in question. Back when, and barely relevant, I got perhaps the best overall quality of sound from my VOTTs with 20 wpc PP tubed amps, but they certainly lacked dynamics. Friends with speakers similar to mine liked their little 2A3 and 45 SETs, but to my ears these were not really in the running for FR, and we did not have crossovers or techniques that made multi-amping any good, either. No doubt it can all be done more effectively than we did it, but I just have to scratch my head at 2V from a 12AX7, etc., controlling an an S2 or JBL 2440.
I would like to hear from anyone with recent practical experience on this front, or furthur considerations on the lower limits of power that one needs to get music from the average MF or lower MF compression driver.
