Oracle Delphi mk3 is it worth it

Hey everyone about two years ago I got a Rega rp8 with a Dynavector xx2mkII cartridge love it. But recently a guy at my dealer is privately selling a oracle Delphi MK3 with a SME5 for a steel of a deal. Only two owners in its life. Should a guy jump on it, will it out porform my Rega. Plus can a guy get the older switches relpaced wit the new aluminum housing and matching switches?
