Mac Mini Power Supply

I recently built a linear power supply for my Mac Mini. The difference in sound quality was one of the single largest performance upgrades I've made to my system in years. I was wondering if anyone else has had any experience with their mac mini PSU upgrades and what your experiences are. It's one of those upgrades I wish I had made months ago. I've always been a big believer in the source being the most important component in the system. Followed by the power supply being one of the most important parts within the component. At least in this case, it appears that was correct. Mintzar  (System | Reviews | Threads | Answers | This Thread) 07-18-10

It makes digital sound less harsh and biting. With the ECM the highs sound more organic/analog. Can anyone explain how this is done with the transformers in the unit? I don't think it really is a power supply. I do have an adapter hooked up the the power supply of the Mimi that allowes me to use a high end power cable. Needless to say the PC does makes a huge difference from the stock cable. What kind of $$$ are we into with such a power supply?
