Like some other Audio-Technica moving magnet cartridges the VM540ML has a low recommended load capacitance range, in this case 100 to 200 pf. And the phono input of your amp has a higher than average input capacitance of 220 pf, while the phono cable, tonearm wiring, and connectors will probably add something like 150 pf or perhaps even 200 pf to that. So I would not recommend that cartridge for this application.
I suspect the total load capacitance would NOT be far enough above the 2M Blue’s recommended load capacitance range of 150 to 300 pf to be a significant issue. Not sure about the Nagaoka, for which I couldn’t find a load capacitance recommendation.
Good luck. Regards,
