How much is a used Naim CD5X worth?

hello - unfortunately, our father passed away and he has a lot of audio equipment. We are keeping the essentials to use with his high end speakers and we have some other pieces that we need to sell to cover funeral expenses. he has a Naim CD5X that is in perfect condition with an owners manual but do not have the original box. does anyone have an idea on how much it would be worth?
First of all, I am very sorry for your loss. Please accept my condolences.

I was going to ask that you go to Ebay and look up the "Completed Listings" section, but I found no completed listings, and I see that you have already posted an ad on Ebay.

Based on these two ads posted in 2013, I would guess that you would do well to get $1000 considering you have no original box. Good luck with your sale.
@jmcgrogan2... thanks for your help. it's a difficult time but we are working through it.
I've seen CD5X on local listings for around $1000-$1200. You can take that price as a reference.

Sorry for your loss.
