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).

Thanks Ozzy.  Did you notice a significant improvement after adding this PSU?  Also, it appears from looking at the rear of the unit, that there are speaker binding posts rather then the normal 12V female receptacle?  Am I missing something here?

Lowrider57,
thanks for your suggestions but I have one question.  How do I find the specs on my RR-888?  I've looked but can't find any info on its specs.  The only specs I can find is on the walwart PSU that came with the unit.  Printed on the walwart PSU:
I/P:. AC 100-240V 50/60 Hz 0.3A
O/P: DC 12V 1A
I can't match the specs of my RR-888, with the specific PSU, as I don't know, and can't find these specs.
Can you, or anyone else help me out?

Lynette,
Yes, the KingRex PSU is now over $400.  If that's what I have to spend that's ok, but I'm trying to research (with the help of fellow A'gon members) if the less expensive PSU's, for the RR-888, would work just as well.
I will try some different PC's,, and thanks for the suggestion to check with Jena Labs to see if that is as effective as purchasing a different, "upgraded" PSU.

Can anyone else suggest a particular PSU that they have used with the Acoustic Revive RR-888 (or 777, or 77)?
Also, do you think this is really worth pursuing?  Will I really get an improvement over the stock PSU with the RR-888?
Thanks to all!👍

Thanks Ozzy, I will give them a call.  Tonight I raised the RR-888 from a height of 5' to 5'9".  Nice improvement.  I feel like I'm really dialing this thing in.  Prior to the RR-888, I thought I had a pretty good soundstage.  Now, it has simply exploded.  Oh yeah!👍👍

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!
