From what I know, there is no comparison between the 540 and 640. Completely different components and build. Not to knock the 540 but I'll bet the 640 will crush it.
Cambridge - 540A /640A ver. 2 Integrated Amplifier
Hello,
I have an NAD C352 integrated in a little secondary system for my dining room. I am not really happy with the NAD, I find it's sound to be rather muddled-particularly in the bottom end.
I was eying two different Cambridge Audio integrateds, their 540A version 2 & 640A version 2 integrateds. I can get either of these without making any substantial additional investment (after selling the NAD). Might anyone have any opinions of these units? Would they be any upgrade over my current NAD unit??
