Question about Teddy Pardo PSU for my DAC

I'm considering one of his outboard power supplies as an upgrade to my DAC, but after looking at the website, and reading a review, I am not at all clear as to how this interfaces with the DAC and the wall outlet. Are there any members using one of these who could enlighten me? I am currently using an Audio Note Kits 2.1 DAC.
Thanks.
