Audio Magic...
I see they offer power conditioners ranging in price from 500 bucks to 8000 bucks. Same goes for their cables. A price range that absurd on its face, for products not involving aerospace engineering, has hype and scam written all over it. It's obviously a target price marketing thing, not a relative performance thing. Manufacturers who build umpteen variations of one product to obvious price points are suspect, IMO. Doesn't mean they don't basically work, but, please.
If the Mini Reference deepened and focused the sound stage, the top of line version had better extend it into your neighbor's backyard...
