Modern vs vintage has nothing to do with it. If the tonearm and cartridge are well mated, the turntable needs to do its own job, vintage or otherwise. So if the JVC is in good working order, you should have no problem regardless of cartridge. IOW, the JVC, like any tt, will have an effect on the total product much the same as would any other tt, regardless of cartridge. Things that improve the tt performance per se will improve the overall result.
