I've no problem being wrong but from what I understand of your setup you are running a 5V from your mobo to your DAC. It would not surprise me that this sounds worse than the previous 5V which was coming from your 2nd Regen?
Do I misunderstand your config?

I run a USB cable from PC to the battery powered Regen whether it's running solo or in tandem with a 2nd Regen. I don't understand your comment. When I ran solo battery powered Regen it was 5v powered by yet another Regen not connected to anything except the mains. I soldered its 5v terminals to get 5v to go to my 3.3v battery powered Regen. Even in single or double Regen the Regen dumps the incoming USB 5v power, as I understand. So the boundary conditions are the same for single or double Regen.

  Right, when you said mobo, it confused me (I'm reading this on a phone) - I want sure where the 5V was coming from, that's why I asked.
  So the 2 Regens is still better than one - very good!

    I've also run a REGEN off a 5 volt (USB) supply rather than the supplied power supply. It seemed to work OK, but probably because my DAC doesn't require 5 volts from the REGEN.

      John Swenson early on recommended the following power supply for the Regen

      I bought one and have used it ever since on my Regan. It made a significant upgrade to the sound of the Regen

        OK, perhaps try a TeraDak U9VA Linear Power Supply w/5V USB output if one's DAC required it?
        Seem to recall that the Audio-GD Amanero board is powered by a liner supply inside of the DAC.
