Do I keep the Oracle Delphi IV/V?

I have an Oracle Delphi Mk IV/V upgraded from Delphi II with custom power supply built by Conrad Johnson engineer, with Morch UP-4 arm. Delphi needs new belt, possibly new suspension and complete tune-up. I also find the Morch UP-4 problematic, in turns of cartridge set-up, and want to replace it.
Question, will turntables such as the Rega RP10 or Orign Live Illustrious with Encounter Mk111c arm have comparable sound to the Oracle, UP-4 combo?

Thank you!
