Cambridge Audio CD Player Question

I have the Cambridge 500SE cd player. If I goto the Cambridge 540C Azur will I hear a improvment in sound quality?
I have seen at Audio Advisor they are selling this unit at the low price of $200.00.
I used to own the D500SE, and upgrade to the 640C version 1 a couple of years ago, and the improvement was significant. I can't comment on the 540C as I've never heard it. A brand new 640C at $343 (Audio Advisor is closing them out) is a screaming bargain!
Ive had both,with the 540c,you will hear a substanial improvement in sound.
