Me, you and them
Its all about energy transfer. The old steel subchassis had a lossy connection to the armboard, most of the energy was lost at that barrier. The Keel dissipates energy by having the webbings at different depths and wall thicknesses, but the stylus, bearing and subchassis are all one. We think thats not ideal.
The RubiKon is designed so that the stylus and bearing have seperate energy transfer paths and the resonant frequency of the two elements are different. Energy will be wicked away from the stylus and noise (etc) from the bearing will not travel through the chassis to the stylus.
I think this is a great set up if does sound better than the overly priced Keel. Harbeth has a great way of putting it. A bell rings, put a crack in it and it stops to ring. This design is along the same analogy.
