High Sensitivity Speakers that work best with SS

Unsound, of course "overdriving" an amp is also not good. But I have never suggested that. With normal speakers one most often uses a few watts (e.g 5 watts) for typical listening levels, whereas with very efficient speakers one most often uses between a hundredth and a tenth of a watt.

Most often perhaps, but even if peak power is only required say 10% of the time, that power requirement could be 10's if not 100's or even 1000's of X the typical amount of power used. Without such power, the system would be in distortion mode say 10% of the time.

Unsound, with all due respect, please leave it at that. Let others with first hand experience in building and measuring tube and ss amplifiers answer my question. It is a perfectly logical question.

I currently use a Bryston 4BSST amp which is 300wpc into 8 Ohms, 500wpc in 4 Ohms. My JBL S4700s have sensitivity of 94db. It's a good combo to my ears. I'm guessing that JBL being under the ownership of Harman, were voiced using Levinson amps. Levinson amps are high powered too. I prefer Bryston soundwise. But that another discussion there. Anyway, the combo works well, and I'd like to try lower powered Class A solid state and perhaps even tube amps. But I'm not really in any hurry to do so...haste makes waste especially in audio!

NVP,
Your thought process is on the right track.The motivation for Nelson Pass`s First Watt line of amplifiers was high quality sound at low power levels.He recognizes that higher efficiency speakers require 'quality' more so than power quantity.These speakers at normal listening levels may use well under i watt(often only fractions of a watt) of power.Some behemoth amplifiers don`t sound their best at these lower levels(nut some do pretty well).
