Price for a VSA Visiun CC

I have a Visiun CC in perfect condition that I am entertaining selling. It is not the signature. Also have a customer made stand to mount below my screen. I believe I paid somewhere around $4,500.00 for it 6 years ago. It has barely been used.

Just wondered if anyone knew of a fair price for it?
I could not find anything in the Audio Blue Book.

Thanks
