Musical Fidelity A 3.2 current market value???

my older brother the doctor has charged me with selling his Musical Fidelity A 3.2 Integrated. Can someone perhaps tell me what the unit might be worth in today's marketplace? He is the original owner, it is gorgeous, he has shipped it me, I would say it is a 9/10 he is pretty meticulous. Original box, remote, manual of course. Oh well, anyway any help would be appreciated, I beleive it retailed fro $1799.00 back in the day
