Dynavector XX2 mk2 vs Lyra DELOS which is better?

Hi every one I am in a bit of a analog dilemma. Just thinking of doing a cartridge upgrade but don't know which root to go. My system Is a Oracle Delphi MK3/4 with all MK6 upgrades but the motor. Paired with a SME4 tonearm feeding a music First audio Classic V2 MC step up transformer. Into a cary sip-98 phono preamp into a Cary cad 120s tube amp and totem forest speakers. I currently own a Dynavector XX2 MKII cartridge that's at the end of its life. I can get it rebuilt for $1300 CAD which isn't bad since I got the cartridge 2 hand for $350 never used haha a score. But my other dealer has a new Lyra Delos cartridge for $2600 CAD. Now I Have only heard the Dynavector since owned one before, and have never heard a Lyra. My real question is the Delos that much better then the XX2 MKII and worth the extra $1300 dollars. Or should I stick with the XX2 MKII because I am already amazed by it and pleased. Let me know your thoughts, Thanks fellow audiogon's.
