Until you can hear a difference, what is the difference? Cost? Status? Aesthetics? Resale?
Do what you can to audition something in your own environs.
I have several 5 disc carousels Yamaha, NAD and Sony, non of which would receive any accolades in audiophile circles. That said, the Yamaha ($11 at Good Will) to me sounds very nice. The NAD skips if there is so much as a smudge the size of a flea's footprint on the disc. The Sony, well I haven't given it much of a listen yet.
If I play ripped (lossless) CDs through the 3.5mm out with RCA 'Y' into AUX in on one of my computers, there is definitely not the same quality of sound as through the stand alone decks. I guess I would attribute that to the DAC process. So I would then assume that a really good DAC would be an improvement over a basic consumer level CD player.
There is a lot to to said for packaging. A piece of gear that both functions beautifully and is a looker certainly has its value.
I know some audio stores have in home trials. If you can seek this out it might be useful.
Bottom line, if it doesn't improve what you hear and it costs you money, let's hope the eye candy is worth it.
Are you familiar with the hub-bub over the original

As a footnote:
My comments here are from a state of ignorance to 'higher' level offerings. I have heard the Cambridge, but not at home. It was played though about $12k worth of electronics and speakers. Not really being in the market for an $800 CD player, I did not ask to try it in my home. I do not object in the least bit to the cost of any of it, I just think a reasonable perspective should be in place when evaluating system add ons/ upgrades.
