Are Altec 515b's really worth this much?

3 bidders were still on them at the $1750 mark.

I'm not surprised. I've been watching the 515b auctions for another pair, and it seems to me that someone hoping to pick up some at the prices of just a couple of years ago (me) may have begun to wonder if they are going to be permanently out of reach. There seems to be a sense out there that there is no replacement for 515b's with original cones.
