Hi. I am looking for some feedback on the following three players: Marantz CD6003 and/or the Denon DCD 710 AE and/or the Cambridge 740C upsampling cd player. Currently I am running a home cinema set up, Denon AVR2808 + B&W 685s (F/L) but musically I want to try & get the best out of my equipment as possible, within my budget. I have plenty of cds to play as well as music on a 5G IPod. Any personal feedback on how well or not these machines play both cd's / the Ipod would be really appreciated.
