- Do you mean that the noise appears to increase on louder portions
- of music?

- It could be that your tracking pressure is TOO LOW. Beg, borrow,
- or steal a GOOD tracking pressure guage and check yours.
-
- SOME cartridge manufacturers specify a lower pressure than others
- because they think the lower number looks good. With most modern
- cartridges, you will do WAY more damage with pressure that is too
- low than a bit high.

-
- If it is due to low tracking pressure, the music just bounces
- your stylus around on high passages. The stylus gouges a small
- hunk of vinyl out every time it lands.
-
- I'd try checking the tracking pressure, and setting it to the
- higher side of the manufacturer's rating....
-
- You COULD have a arm/cartridge mismatch or resonance, but you'd
- need advice from a high-end shop for that...
-
- Usually the passages which are sounding noisy IF due to low
- tracking pressure (or poor compliance and match of arm/cartridge)
- are said to 'shatter'. The term is pretty
- self-explanatory...loud passages sound like they are being played
- thru a concert of breaking glass.
