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.

The mini runs on 18.5Vdc and draws no more then 6A.

Connector and cable can be purchased fronm here: http://store.mp3car.com/MacPac_Power_Cable_Kit_For_the_Mac_Mini_For_Mac_Mi_p/cbl-086.htm

I just saw this post, sorry for the delay in response...

Power supplies can be ordered through Core Audio Technology's website or contact me from there. Plenty of reviews on the Core Forums also.

Yes, I remove the switcher and insert an additional filter inside the mac mini chassis. My power supplies are then run externally.

I buy a stock PS brick, chop off the cable and add the necessary caps and resistors to make it function.

Why do this if you can purchase a new cable?
