Original V15Vxmr cantilever was Beryllium, the lightest/stiffest/ (but brittle, I broke mine), on my TD124 heavy platter, the best bass I ever had, and tracked at 1.25g, which is why I consider 2.0g ’heavy’.
The Top Shure's each came with their test performance graph, similar to what I got with the Sumiko Talisman S I bought for it's stiff Sapphire Tube cantilever.
The Bass, 3 lp set, excellent listening as well as demo collection
After shattering the Beryllium, I go no stiffer than Boron these days, and yes, my V15Vxmr body with Jico SAS on Boron sounds darn good,
the Shure Stylus’s Brush (use up or down, add 0.5g in use, it pushes up 0.5g) is damped, the Jico Brush is just a brush, no damping, they do not give you precise calculations for tracking with it up or down).
Using the Jico brush, how do you measure and what tracking force do you use ______?
Using the blank side of an LP to ’see/set’ anti-skate as you adjust for it is even more important when using a brush. The needed anti-skating force with brush in play is a hint as to the actual tracking force you are getting.
In my office, same era, I am rotating/using AT-440ml, (aluminum cantilever) tracking at 1.4g. Their current AT540ml tracks at 2.0g. No brush on the ATs. The AT440 is similar to the sound of the Shure but I convinced myself the Shure had more bass.
