Yes. The CD8x is better than the Rega Apollo. You must bear in mind that the CD8x was a £1000.00 kit compared to the Apollo at £600.00, so if you are able to get one now at the Rega's price, then you should seriously consider it.
I had one infact, but I sold it as it sounded too lean on my system. The Rega Apollo fits in very well now, aesthetically and musically, and does the job splendidly for me,
Make sure the rest of your system is cohesive with the CD8x though. With Cyrus, the right pairing is vital for maximum benefit.
