I agree, that's the way to do it. Nevertheless, I personally wouldn't use
a
valve amplifier in this application as the electrostatic panels are a
pretty
severe load. Having said that, for $90, it would be a fun thing to do.
Endless playing around with the treble/bass balance, crossover frequencies
and slopes. Much more fun than just listening to boring music.......
