PSU's for an Acoustic Revive RR-888 (or RR-777or RR-77)?

I finally purchased an AR RR-888.  From what I have read, one way to improve the performance of the RR-888 is to upgrade the walwart PSU.  I've read that the KingRex PSU is a great match, even though it is now over $400.  I'm curios if any Acoutic Revive RR owner is using the CIA Power Supply.  If so, which CIA PSU are you using?  
Also, there are comments about ordering a Linear PSU from China, off of EBay,  If you are using one of these PSU's from China, off of EBay, which unit are you using, and what was its cost?
Lastly, what do I need to look for in a PSU, other then it needing to be 12V?
In advance, thank you for your input, and I look forward to hearing about your experiences when upgrading the PSU that comes with the AR RR-888 (777 or 77).

had great luck w/ this. R-core tranny & good parts. was a massive improvement vs stock (caused a physical sensation w the 888 for a few hours til i adjusted), and won in a shootout vs a couple others (not the high $ ones mentioned above, which were not included).

Lowrider57,
I will check with The Lotus Group (distributors of Acoustic Revive) to confirm the power specs for the RR-888, prior to purchasing a new PSU.  Also, I will do some internet searches on these PSU shootout so.  Again, thanks for your guidance!

what power supply did you end up getting? I have a 888 on the way and I'm already thinking ahead.

If anyone is still reading this thread, I hope you can give some advice. I'm thinking about buying an external PSU such as the Kingsrex or other, but need to know the size of the dc plug input. In a thread on another site, someone wrote inner diameter 2.0mm, outer diameter 4.5mm. Can anyone confirm this is accurate? And do the measurements need to be precise?
