Naim CD player question Which one

So I've been looking for a Naim used CD player, and I've come down to two... A CDX from 4 or so years ago and a Display model CD5 from a local store. Both are right around $1600 but I'm a little weary of an internet buy when there is still a 1 year warranty at the local dealer. I definitely want to keep the price in that range, which is around the new CD5i. Any thoughts?

Current system Rotel 1056 receiver to Quad 22L speakers... I may end up getting a Naim amplifier too, or possibly a Quad 909 to brand match the fronts.
