Comparison new and old SAS stylus (Shure V15vx)

Postby Thomas_A » 20 Apr 2018 18:35

Just want to share information regarding comparison of an old and new SAS stylus (9 year vs new, SAS boron on a Shure V15Vx. Below are files from an inner track of the Smiths Cementry gates followed by some measurements. There are significant differences compared with the same loading. However, using a different loading, the difference is perhaps less? Just wonder when you need to change stylus.

New stylus loading 130 pF/47 kOhm:

at the same loading, new stylus has slightly less IDG. I am still surprised SAS can still sing after 9 years.
810pf/27kohm loading seems to provide more warmth(more focus on vocal) to or muff the sound, depending on listener's preference.
I think the original recording of cementry gates is on the bright side, so 130pf/47k loading is more neutral to me.

Yes it appears that the old stylus holds up well. It is difficult to say how many hours it has been playing, but some things also change with age, such as the rubber suspension.
