If you listen some each week, I suspect you are wearing out your stylus before replacing it.
IMO, no matter what cartridge you choose, you ought to get an advanced stylus shape. The ZU Denon is conical
"0.2 mm square base diamond, crystal aligned, conical cut"
Hana S series is Shibata, a great choice.
