Commentary
VM type cartridge corresponding to the highest grade model.
Materials such as tapered cantilever, ultrafine particle polished SHIBATA needle, high-energy dual magnet, super permalloy pole piece are put into it, and it is assembled with ultra-precision by selected production staff.
The body uses die-cast metal to shut out harmful micro-vibrations and improve the low-level resolution while improving the shielding effect.
It has a gold plating finish.
