I think it would be helpful to know a bit more about what you are looking for, such as: how much have you budgeted for the changer?, how many CDs would you like it to hold?, are you willing to buy something used?, what do you currently use to play CDs and are you hoping for something that is better than this or are you willing to sacrifice sound quality for the convenience of the changer? I believe that the largest changer, a Sony, holds something like 400 CDs, but, I don't know when that machine was last made.
I am very much a CD person, but, I've ripped them all to a server (still keep the CDs). I don't know how large is your collection; mine is about 5,000 CDs. From a practical perspective, it is not easy browsing my collection, finding what I want to play, or returning CDs to their proper location in my collection so having everything organized on an iPad, with multiple ways to search for music, ability to make play lists, etc. has become more than a convenience, it is pretty much a necessity. Particularly with Jazz, it helps that one can search the artist and find CDs where the artist is not the headliner under which I would have filed the CD physically.
Is there a reason why a changer is more desirable than a server?
