New preamps making new claims.

Actually the economics work like this: When a manufacturer introduces a new version of the same product, then all the retailers/distributors have to get rid of their display model and show the new version, and they are frequently under contract to do so. So they goose up their profits, at the cost of the dealers.

The dealers then thumb through their rolodex for their top group of customers, who can be counted on to trade in their "recent" stuff for "new, improved" stuff, and the dealer makes back some of the profit they lost having to sell off the display model for cheap.

Used/discount buyers then buy up the display model and the customer's trade-in . . . but these people usually like to change out their gear a lot, and the value of this particular model has plummetted since the new one came out, so they all, in turn, lose money on it until it ends up in a landfill.

And after awhile, since people don't want to spend much money on something they're going to be getting rid of . . . the manufacturer has to sell their stuff cheaper, in order to keep their sales. So they start the cycle again . . .

. . . and we all start leveraging our credit with each other to keep it going, but nobody knows how much debt each other has . . .

. . . well, you get the picture.
