50V would be OK, but as close as I'd want to cut it.
Yes, but I'd also wonder about the power amp module or output devices.
Heat is the enemy, but fundamentally - and were it mine - I'd want to make sure that the gizmo is rated for use with a 30 V power supply -- which it may well be. I skimmed the posts and didn't see what it was.

Is whatever amplifier you're using designed to be used with 30 VDC input?
E.g., the working voltage ratings of capacitors therein.
If not, 30V might shorten its life considerably.
