My understanding is that it's no clone; for the history of the amp, you'd probably be better off asking one of the Stratos owners. I believe that these are all original production and pretty well made.
As for myself, I was just thinking aloud. I don't have a pressing need for a new amp for my bedroom. I suppose a new B&K for about the same price with full warranty would be a better deal. I could probably buy an NAD C-370, too, for the same money.
