Proceed HPA2 & HPA3 Amplifiers & AVP2 Preamplifier

I inherited these amps.  I have no interest in them for they are way to much for my home along with the Bower & Wilkins Nautilus 800 Speakers.  Any ideas what I should do with these? The worth?  Sell??
i know its been a while since you posted this, what did you end up doing with these?
