Hi Raul,
Thanks for the suggestion. However, after reviewing discussions with Axel and holding lengthy discussions with Franz, the nude shibata on aluminium cantilever were felt to be optimum resonance and performance combination for my given cartridge (the Acutex 420 STR). So I've repeated that exercise to genuine joy.
I'm not dismissing the possibility that your suggestion of the shibata and boron combination is not valid. It is just that I have no experience in hearing this combination on said cartridge. However, if you can give me more details about how these perform, I will consider taking that option for one of my styli. If you want you can do this off line by email.
BTW, great to speak again on Agon.
As always...
