    I'd suspect better again. What cartridge is that on?

    It was on an Ortofon 90th Anniversary Model, I can’t recall any model numbers, I saw it online, not in person so I just recall the author was making extra mention that the cantilever was diamond. A first apparently? And they were practically giving them away at the asking price!

    I have a Dynavector Karet with a diamond cantilever.

    It has a very fast and distinctive sound; you certainly sit up straight when drums etc are involved - completely different to the laid back KB which I also owned until recently.

    Ah, the ortofon MC A90. I didn't see that it had a diamond cantilever. I'll check the spec.

    Hi,

    Boron is generally a stiffer and harder material than Ruby. There is not much in it. Boron can be made stiffer by in componds such as Boron Carbide.

    I'm sure I read the opposite. Happy to be corrected though.

    Wasn't Boron unavailable for a while?

    Boron is getting harder to source, so manufacturers are looking for alternatives.
    One of the reasons the high end Technics cartridges were highly regarded is due to the boron pipe cantilevers.

    I'm just about to delve into this a little.

    Hi,

    Diamond is even stiffer than Boron.

    Ortofon have a diamond cantilever cartridge called the MC Century




    Carbon fibre nanotube and Graphene has diamond stiffness.
