Blue ray and cd player combined?

I am considering buying a new cd player as my current one is quite old. I have a very nice home entertainment set up. Nautilus 802s driven by Classe amplification. I am looking at purchasing a Cambridge 740c cd player.I listen to blu-ray music dvds as much as I listen to cds alone.The sound from my Blu-ray player, an old Sony, is better than the sound from my 13 year old Nakamici Music Bank 2 cd player. I am considering buying a Marantz BD7004 blu-ray player,instead of the Cambridge 740c. I have been told that it plays music cds as well as blu-ray dvds. I am wondering how much reproduction quality, over the Cambridge 740c, from straight music cd playing that I would be sacrificing by going this route. Any help would be appreciated.
