Changing from a beryllium cantilever on the stock V15VxMR to a solid boron rod with the JICO SAS replacement stylus drastically changed the tonality of the cart. The original sounded rolled off in the high end while the SAS made it closer to neutral, but still is subtly bright (comparisons were made with vinyl that had a CD counterpart released at the same time). So... it can't be stressed enough that changing any part of a cartridge will potentially change the tone in a fundamental way.
Boron Cantilever and Ruby Cantilever, Why Ruby?
I have noticed that many of the better cartridges use Boron cantilevers. I know that Soundsmith uses a Ruby cantilever. I was thinkin of having my Benz Wood Body cartridge retipped but was not sure if the different material used for the cantilever will impact compliance and even sound. Why not boron like the original?
