Sim Audio Moon Air Tuner.....any experience?

Does anyone have any actual experience with the Sim Audio Moon Air tuner? I know it is based on the MD-102....but what is different....and is it an improvement?

There is a very nice review on this tuner in a recent issue of HiFi+ magazine, I can't remember exactly which one but thier website is and they sell back issues. For my money this is by far the best hifi mag on the market.
I bought one last year and still have it. I upgraded from a Magnum Dynalab 100. What you will get is big reduction in background noises. I don't think you will go wrong if you bought one. A MD-102 at the same price range should also be considered.
