Frank Kuzma is releasing a new arm!

Looks like a Kids Toy

Waste of money! You can buy a new car instead.

You can buy a new car instead.

And that comes with how many wheels?

Time to reassess your grasp of the real world. 

@dover, You have your tonearm geometry mixed up. The SAT arm is a stable balance arm. In other words it will always return to the same balance point after a period of oscillation. VTF changes with elevation. The 4 Point is a neutral balance arm. It will stay in whatever position you put it in. VTF stays constant regardless of position. Yes, the new arm is a heavier arm which means it is limited to cartridges that are on the stiff side. There are plenty of those. As it is very short, shorter than a Rega arm it's moment of inertia is low in spite of the mass which is more important than EF. It's major failure is it's price. Would I buy one? Certainly not for a Lyra Atlas. 

Let’s spare ourselves the obvious jokes about its cost. The elephant in the room is that this tonearm is an elephant. At 60g effective mass, not many if any cartridges will qualify, if you base tonearm matching upon the equation for resonant frequency or even bring it into the buying decision? And yet its mass will be ignored by the well healed cognoscenti, because it is so expensive. In the minds of many with big bucks, cost can overcome the constraints of the physical universe. Even Fremer, who mentioned this product, its cost and its effective mass, in his most recent newsletter, didn’t bat an eyelash over that last specification. We shall see how it is ultimately viewed.

Just read Mijostyn’s last post after having posted this. I don’t see how you can divorce effective mass from inertia.
