Recommended mass would be 9-around 20ish
Interesting, we'll see. I may have an opportunity to hear one soon. It's not so much the notion that a high end cart must have a diamond cantilever than the facts that aluminum is less stiff (than even Boron), higher in mass, and it resonates. Perhaps there is something inherent to this "straight flux" design that doesn't care about stiffness and added mass (though that seems hard to fathom), but the resonance properties of Aluminum are still a potential problem. Proof will be in the listening though, and again, I hope to do so soon.
Diamonds are an audiophile's best friend?
