Repeating what Justlisten said - isn't there a way to get some help from audiogon or better yet from Pass Lab directly? In my view, the only way these prices can possibly be real is if this guy is (or was) a dealer who now wants out, but Pass Lab for whatever reason is not willing to take the stuff back -- consequently, he is forced to recoup by selling at dealers cost.
