Digital Linear Power Supply

In order to get my Mac Mini out of the chain, I just bought a Bryston BDP Pi today and my dealer told me about the Bryston linear power supply upgrades. The cost of those upgrade options are more than I’m able to afford. I know about the Uptone Audio LPS 2 though I’m only looking to power the one component. Also a choke filter type linear power supply is enticing but I only have a basic understanding of what that is. Any suggestions along this matter would greatly be appreciated.
This SGC LPS will do the job. You can get an equivalent with a Talema transformer direct from China for half $ but it will take a couple months.
The next step up is a Keces P3 for ~$400 new but if you're patient they often come up used as power requirements change.
Thanks fuzztone. 12 volts is what I need so either will do. What is the advantage of spending more on the Keces P3?
I've had excellent results from TeraDak and Zerozone power supplies on ebay, such as this one:

Some of them actually use really good components.
Auxinput, I was looking at the Tera Dak. I know they make other high end components.
