my memory could be wrong about the $15k, sure, but note that there are two pairs of 9's included. and everything looks to be in great shape.
from what i have seen, the really collectible stuff hasn't seen a catastrophic drop in selling price in the last couple years, but i'm sure there are exceptions.
My mistake, if there are two pairs of 9's in this deal it would be right and fair. I read it but failed to see that there are four (4) Marantz 9's in this deal. I guess his pricing is right on then. Would hate to see the rack split up, but someone with dough could get it and split it if they wanted, and probably make money on a piece-by-piece basis. They are clean though.
