It would be really interesting to put a scope on it (or better yet, a power analyzer) and see what the distortion is like feeding your sound system. In any case, the Powerwall is awesome and I’m seriously considering one or two.

Listening on tesla only is as good or better than grid, the noise harvestors are still very active during battery power, so you're probably right. Even though the hifi stuff is on dedicated circuits there's still something causing harvestors to blink. I don't hear noise and maybe it's in my head but it does sound a smidge better.
