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.

Thanks for the kind words, Earflappin. It's truly wonderful to hear that you had such great results. And that I'm not hearing things!

Just an FYI, I haven't sold any PSUs to anyone on acircle. So if they are comparing linear PSUs to a stock SMPS they aren't comparing mine. The Boulder and PH Design PSU use good regulation, but inferior parts and filtration everywhere else compared to my supply.

That isn't to say the new SMPS in the 2010 Mini is bad or that their claims are untrue. I'm just trying to be fair in what is being compared. An HP bench supply may be a linear supply, but it's highly unlikely that a bench supply will sound better than the stock SMPS. Bench supplies are designed for adjustability and testing, not for audio purposes or clean power.
Why spend $400.on a linear PSU, when you can have better sound,lower power consumption and less boxes and cables by upgrading to a new Mini.
The new Mac Mini has a new video chip that's better. So if video is your thing you will get some benefit by going to the new mini for video.

I've read that there's virtually no audible difference between the 2010 Mini and the 2009 Mini, both with stock parts.

I can think of no reason that putting the supply internally in the Mini would make it better. If anything, you would have more power supply noise leaking into the motherboard. The supply would be smaller, have less filtration, and more issues from switching noise.

Kana, I'd love to hear more about the comparisons that were done and what supplies that were compared. It's difficult to give your statements foundation without a little concrete to back them up. If the new Mini really IS better
It'd be great to know why.
Mintzar, unlike you I'm not trying to sell linear power supplies.

I don't own a Mini and I don't plan to buy one.

If you want more info, go to audiocircle and read the posts from people that have compared the 2010 Mini and 2009 Mini.
Thank you for posting your comments about the 2010 Mini, I (and I'm sure this goes for other people reading the thread as well) appreciate the opportunity to be able to do more well-rounded research and comparisons.

Bare in mind, the 2010 Mac Mini compared on the Acircle thread was decked out with all kinds of modifications and specialty software. The people who compared stock to stock heard no difference or a small difference.
