I've still been running mine off of the 30V adapater that Tronographic provides. I've been having no luck in getting Voodoo Lab to return my phone calls so I can buy the 24V (12V + 12V with center positive) adapter for my PP2+.
I've been curious about the reduced headroom as well, but an email that I received from Tronographic about it made me feel better. Basically they said that the reduction of headroom would be pretty minor, and that it tested OK in conditions even lower than 24V. Obviously the higher voltage is preferred, but I'm not too worried about 24V operation. I want the thing to breakup a bit, so the knob position of the input gain can just move down a bit and I'll be back where I was.
