Replacement for Pfanstiehl 771-DE 771DE needle stylus

I had purchased an original Shure M97 with a broken stylus, so ordered this to see how things went. It turned out one side was dead , so I then installed it in a M97xe that was laying around. It fit ok, but actually sounds better than I’ve ever heard this cartridge sound, and I’m hard pressed to identify a huge difference to my V15 type iii.
