Frank, Yeah and nobody else has a clue. Those of us who know, the only question here is how good a copy do they have? If it is a really good knock-off then it could be worth every penny. Only problem with that being, who of us who has tried the real thing is gonna fork over to find out? Few if any. Okay so then so if someone does try it, but they never tried TC, then how are they gonna know just how good it is? They aren't.
The conundrum is, we know it is entirely possible to make something so good nobody can hardly even believe it. I mean even you and me who have used it all over the place, even we can hardly believe how good it is. Like you just said, fricken PC sounds good now. Crazy. But that is up against a crowd where some of these guys are so dense they still don't get that contacts cleaned with ordinary alcohol is an improvement. They don't get anything. Zip. Nada. If it ain't an amp or a speaker it's snake oil.
Oh well. At least we got our insanely 'you are there' systems to enjoy. It all evens out in the end.
