I will try fistly change my cartridge... VM95ml or VM540ML.. after i will study a best turnable!I would say yes, your AT, like any turntable, will improve with a better cartridge.
When I had my Pro-ject Xpression 1, which cost £200 new, I had a £130 ClearAudio cartridge fitted and it gave me an impressive uplift in sound.
Just for the record (excuse the pun) I've also owned a Ortofon red that doesn't compare with any of the Clearaudios or Goldring carts I've owned.
