Personally, to simply solve LP volume, tomorrow in time for the holidays, and make big changes later, I would change to a MM cartridge, powerful output, this one is 4.5mv.

Your Moving Coil is high output as noted, for a moving coil, however, it's 2.5v is not enough for your Denon, your current problem.
Any new high output MM cartridge will be your base of comparison in the future. I have supposedly better, both
Shure and Audio Terchnica micro ridge stylus/cartridges, I prefer the Shure 97xe, elliptical like the one above.
Shure is out of the cartridge/stylus business, so the price went up, which is why I did a quickie search, the Audio Technica came up.
Later, I would encourage a new amp, and a new preamp. Using MM rather than MC will both widen the preamp choices, and lower the cost, new or used.
I would also recommend you try tube preamp with good MM phono first, and then, depending on your speaker's efficiency (high please) try tube amp.

If you take the 'change only phono cartridge now' approach, I am sure members here can suggest alternates to the one I quickly found (never heard it, but like other AT models I have owned).
Best of luck,
