this will get a slew of responses, let me just say that you are sure to be told that a high action makes the guitar louder, which is simply a hoary old myth.

if you play "hard", with a flatpick or even while fingerpicking, then a high action will reduce the incidence of buzzing, but it won't make the guitar louder.

the increased break over angle of the string at the saddle with a high action has a theoretical beneficial effect on the sound, but that is not a function of high action per se.
