Need a New CD Player

Time to buy a new CD player. Have done some research and it appears as though the Marantz has the audio properties that I want for the amount of money I would like to spend. CD 5005 and CD 6005 models are what I am looking at.

Has anyone compared these two head to head? I am wondering if there is any kind of sonic difference between the two. I noted the 5004 is not as adept at playing analog recordings as the 5005 or 6005 and I've ruled out that model.
