Price Difference Worth It??????

Is the price difference between the Cambridge Audio Azur 540c and 640c really worth it? Does the 640c sound that much better? Anyone have either of these players? I have an older Cambridge cd4se and it's time to replace it.Any input would be appreciated.

The 640c is supposed to be much better. Call the guys over at
www.spearitsound.com They sell CA and they will give you an honest opinion. They steered me to the MusicHall 25.2 CDP over the 640c over the phone.
