heh -- you can take the analytical scientist out of the lab, but... well, you know.
so...
I just searched completed auctions at eBAY for Dynaco A25. The average (mean) can be misleading; we have a cat which is grey on the average (the cat is black and white). The median (price at which half of the sales were above that amount, and half below) and the mode (most common price) are probably better estimators of the "typical" (base-case) value of Dynaco A25 speakers recently sold on eBAY -- given that the dataset is relatively small ("n" of circa a couple of dozen); and given a decidedly non-Gaussian distribution of data.
Looks like the mode (i.e, the most common price) for a pair, actually sold (and not counting shipping) from that marketplace is about $200.
(which, frankly, I find shocking. I'd say a pair of A25s, used, are a good $75 pair of speakers)
I can do a more thorough statistical assessment if (and only if) anyone's actually interested
