My current CD player has died and I am looking to replace with either the Cambridge 640 V2 or the NAD C542. Amp is an old Pioneer A400 and speakers are AR M1's from about the same vintage. Which of these would be the better option. I notice that the NAD is around 80 pounds more expensive in the UK, is it a better player, as here in Australia the NAD retails consideraby cheaper than the Cambridge?? Any advice appreciated.
