Dear Frank: I think that with 40 hours in yor cartridge right now is not the time for cartridge fine tunning. IMHO you need at least other 20-30 hours and then along the load impedance you will need to revise the cartridge set up: VTA/SRA, VTF, overhang, etc, etc.
You need that the XV-1 be settle down before any " serious " listening or set up changes.
Regrads and enjoy the music,
