It's difficult to do that though isn't it, because it's inherently then also a function of the recording and your playback equipment.
Much like you can't expect a (useful) recording in a speaker review.
It'd be a bit more reasonable here I suppose because it's almost certainly going to be the weakest link, so everything else is to some extent preserving characteristics of it.
My expectation is that the PWM output would sound characteristic / interesting enough that it would be worth hearing a recording -- but maybe I'm setting myself up to be surprised if it has a reasonable amount of fidelity.
