Marantz SA15S1 vs CD50N.

Hi, I have a SA15S1 that is not taking cds anymore. It does but it can refuse 10-20 cds then take one. Been like this for a while.
Also mention that it has extern clock/powersupply, so when it works it sound real good.
I change the lacer 4-5 years ago.

So, now I think maybe its time for a new one, how does the CD50N sound compare to a original SA15S1?

Must step up to SACD30N to sound as good?
