Stylus For Gauge - Do I really need one?

What does a high compliance cartridge have anything to do with the Shure's accuracy?

My take is that the VTF is more critical with lower compliance cartridges because of the compliance itself. Higher compliance is more forgiving when the stylus rides over minute bumps and warps, where as the lower compliance cartridge will force the stylus into the vinyl in these situations. Like the difference between riding in my truck with heavy duty suspension and, say, a Lincoln Town Car. Just my opinion.

On the other hand, I have found both of my Shure VTF guages to be biased by not an insignificant amount when compared to the digital guage. It is also not so easy to get repeatable readings on them as compared to any decent digital guage. Again, the digital guages aren't required unless you want the best performance. I'll never go back and neither will everyone I know who has tried one. To each his own.

The gauge recognizes only stylus force; it cannot distinguish cartrige compliance.

It is not the effect of compiance on the guage, it is the guages usefullness in getting the VTF as close as possible to the manufacturing specs that matters. Higher end cartridges are more responsive to getting the VTF right and they tend to be of medium to low compliance. The Shure guage is just not that good.

>>Higher end cartridges are more responsive to getting the VTF right and they tend to be of medium to low compliance.<<

No. That is not correct. There are many "higher end" cartridges of medium to high compliance i.e. 15+ that require precise VTF adjustments. The list, although not comprehensive, includes Zyx, Clearaudio, Benz Micro, van den Hul, Grado, etc.

Actually most any cartridge requires precise VTF adjustment for optimum performance be it high or low compliance. The gauge, as you point out, serves as a starting point; final settings must be based on the user's ears. If you accept this premise than your argument is flawed.
