No one could say from the information provided whether your Grado needs replacement.
- Have you checked the cartridge setup and alignment thoroughly, or had it checked by someone who knows how?
- How old is it? If it's more than ten years the suspension parts may have started to deteriorate just from age.
- How many hours on it? If it's more than 1,500 or 2,000 it's probably due for replacement.
BTW, Grado's are not famed for being the best HF trackers. Distorted highs, especially on inner grooves, is one of their frequently reported "features".
