Hello I have Denon DCD 615 CD player and i want to uprgrade to Cambridge Audio azur640c V2. Can you tell me a little about this player (Cambridge), is it good and is it worth to go for it? How much will i actually hear the difference between these two? Cambridge is 5 to 7 time more expencive than Denon but does it sounds 5 to 7 times better? I have vintage gear, Sansui AU 317 amp and Pioneer HPM 40 spearkers. Am i going to get "real deal" from Cambridge with vintage gear? Thanks a lot.
