Hello! About four years ago I got the Marantz Reference Turntable. I have really loved it and have played it A LOT. Some days, just playing records for 8 hrs straight. Well the last month I hear high end distortion on most records, and I'm thinking it's the stylus. Here's the thing, I actually have never worn out a stylish before I think. On my previous tables (lower ended) I kept replacing the cartridge, just because I could, or the tables. (Went from Technics 80s to Pro-ject to Regards to this Marantz). I want to replace the stylus, the needle itself. I can do this without replacing the whole cartridge, right? What needle should I get? Is this a good instinct for this newfound distortion issue? Thank you for any help.
