Query: Excellent for my DAC & Phono Preamp

I am supplying power to both my DAC and phono preamp with this power supply. There are noticeable improvements to sound quality upgrading from the wall warts--a veil is lifted for each.The phono preamp I am using is a BBE and it wants 12V DC, so I just connect it directly to this Pyramid power supply.For the DAC, I have the FIIO D3. It expects an input voltage of 5V DC (normally powered off a USB bus). So what I did is buy a few parts from Radio Shack for a few bucks to make my own voltage regulator--a 12V to 5V voltage regulator IC, heatsink, small perf board & little project box. I just place this DIY voltage regulator in between the power supply and DAC.Love this power supply--hugs & kisses.
