make sure u are using the stock headshell, it puts the cartridge lower than other aftermarket headshells.
to level the assembly level the platter in all directions, put a small round level on top of the flat part of the headshell (temporarily adjust vtf to compensate for the weight). then adjust tonearm height dial to level the headshell.
use of a thicker mat helps with my cartridge, i use a 4mm herbies, stock mat is 3mm.
also i believe many use a spacer on top of the cartridge to lower it further and add mass, which helps with the system resonance.
it looks like a denon cart is about 2mm too short to be level on a stock GR at the lowest tonearm height
