Avalon Eidolon Diamond price

Wireless200,
I have found the bluebook to be off by multiples of what it says. There is an algorithm for 'older' equipment which means things are way off unless there are lots of sales through Agon's system. For old things with few sales (if any) through the system, it is almost useless.

I have just had a brief perusal of the BlueBook. Some things are indeed better marked. My amps and speakers, in both systems, seem to be in the ballpark of where things trade or would trade, even though I rarely see them trade (other than one set of amps, which I occasionally see). The prices and pricing methods for all things analog and old, however, seem to be way off - miles and miles in some cases. I, for one, will take any and all Technics SP-10Mk3s in working condition at 2x BlueBook. And when I look at ZYX carts, the Bluebook shows all current prices at exactly half of original MSRP plus or minus $10-15 (no matter where it is on the pricing curve), and that cannot be coincidence. I recently looked at analog stuff because I started looking at offering equipment on Audiogon for the first time and I was flabbergasted at what I saw (or did not see - many products just aren't there).
