Bjbcab,
Explain what you mean by "upgrading through Wilson"? If you mean that there is enough profit margin for dealers to offer generous trade in's, well that can vary from dealer to dealer and how far up the chain the customer is going. But that has nothing to do with Wilson Audio as, I think, you suggest.
My statement of a massive depreciation hit is a fact. Look as the asking price four Sasha 1's listed right now. A dealer might take a bit of a loss on the trade, but that goes back to the profit margin. Which, once again, doesn't have anything to do with Wilson Audio, other than their pricing. The fact that a dealer might absorb some of the depreciation to make a sale, which is a dealer choice and has nothing to do with Wilson Audio, doesn't mean the massive depreciation didn't take place. The Sasha 1 is probably now worth 16-17k. That's pretty massive in my book. And just wait until the reviews of the Sasha 2 come out and say how much better the new tweeter is.
I really don't have a clue what you're talking about. Your dealer's conduct, which I'm glad you're happy with, has nothing to do with my comments about Wilson Audio.
