How to Share power supply?

I'm interested in implementing this -
CD DAC Lampucera lampizator

Into a PPA within the same chasis.
The question is, how do I get the power supply to work with it?

In short, you can't, without significant modifications to the PPA.

PPA is a virtual-ground amp, so the power supply's "-" output becomes the negative supply rail for the amp, and the signal ground is virtual. For the lampizator (or for that matter, most other DACs), the "-" supply rail is ground.
