I will continue with my own "research" about Grace LEVEL II
Interesting facts:
This is what Technics invented in the 70’s and improved in the 80’s making cartridges like 205c mk4 with very special Boron Pipe cantilever.
It’s nothing but a grown crystals of Pure Boron into a pipe configuration (wow). A tip mounting hole made using a laser beam.
BUT This is pretty much the same that another japanese company (Shinagawa Musen Co LTD) made in the mid 80’s with Grace LEVEL II BR/MR but with at least one serious advantage over the Technics. The difference is the type of the low mass stylus tip. When you comparing Technics Elliptical to the Grace MicroRidge you know that Elliptical simply can’t win (elliptical has very short lifespan).
This is a Micro Ridge shape under the microscope.
Furthermore, type of the cantilever and the whole moving mass is very important according to this Technics research published in their catalog. Here is the moving mass in relation with high frequency peak on this diagram again. They are comparing Boron Pipe to the Diamond Rod.
Personally i prefer Grace LEVEL II (Boron/MicroRidge) over the original Technics 205c mk4 (Borron/Elliptical). Tried 6 samples of Technics 205c mk4 and 4 samples of Grace LEVEL II. All Technics carts came with weak suspension/damper. All Grace cartridges came with perfect suspension/damper. Both carts have rare Hollow Pipe Boron with laser drilled holes for nude diamonds, but the MicroRidge tip looks shorter than Technics Elliptical tip and obviously has lower mass.
p.s. all pictures made by myself with the actual cartridges from my collection
