I am familiar with the speakers and used to own the Quantum 3's back in the day.
From my perspective they are cool speakers and if you could get them for a reasonable price they might be worth playing around with... However, for the guy's starting bid of $2500, you could do way better. In fact, I'm sure you could find a nice pair of used RS-1B's for less than that and they are considerably better speakers. For that matter Kappa 9's would also be a better and less expensive choice.
Indeed, for $2500 there are lots of better speakers than those... So unless you have some sentimental attachment (like you lost your virginity while listening to a pair), I would pass on those and keep looking. Personally, I'd only go $700 to $1000 tops on that model.
