Man, I'd love to have an Eames myself, but if you're talking about audio you probably don't want that reflective leather right behind your ears. I cut down the back of my current listening chair (a cheap Eames-ish knockoff) so that it was just at shoulder height, which helped a lot. If you could get a hold of a dentist chair that'd be slick. Narrow headrest, motorized adjustments...you'd be spoiled. Not that aesthetically pleasing, though.
