Tube Audio Design (Paul Grzybek) Tadac dac question

Does anyone out there know the DC voltage requirement for the late Paul Grzybek's Tadac tube dac? I own one and want to add a linear power suppy.

According to the online specs, this DAC has a torroidal transformer and solid state regulation.

Why do you need a LPS?
