Upgrading from Rega Apollo to Rega Saturn CD??

The Rega Apollo is a very good player, but after 3 years of ownership, I would like to get something better. I considered just upgrading to the Rega Saturn, and despite its great reviews, I am hesitant. I am hesitant as to how much better the Saturn will sound.

If I sell the Apollo, and buy a used Saturn, the difference could be $600 or less. If I buy a new Saturn, I know I will have to put in another $1200-$1300. I want to avoid that type of expense, despite the fact that Rega has dropped the retail price on the Saturn to $1895.

So, I like to hear from members who upgraded from the Apollo to the Saturn, and can inform me about the improvement in sound, and whether in the end it was worth it... OR MEMBERS who owned the Rega Apollo and upgraded to something OTHER THAN THE REGA SATURN.....that did not cost a fortune, AND IS A DEFINITE UPGRADE IN SOUND.
