There are a LOT of AC power supplies out there in industry, the PS Audio Powerplant does the same thing(according to the Stereophile interview). I used to use a lot of these at a former company. They are not cheap(but not normally $8000 either). I don't remember the companies who make these products, but if you are interested you could search: 1)the Thomas register(a series of catalogs used by American industry - like the B to B Yellow pages), 2)on the web, or 3)ask an electrical engineer. Oh, one more thing, the faceplates on these units are not meant to impress audiophiles, they are industrial equipment. So if you are the type of person who buys equipment for looks, you are sure to be disappointed. On the bright side, you won't have to pay audiophile prices(whatever the market will bear)/markup either.
