The new “NOVEL” EMT cartridges feature technology distilled from 6 years of their own research into the magnetic and mechanical properties of the MC transducer. This has resulted in a whole new design, featuring a double-layer core which reduces Eddy Current losses, on which the coils are wound. A high strength titanium structure (with Diamond Like Coating) which holds a Sapphire cantilever is attached to the core and tipped with a Multi-radius diamond for accurate tracking into the highest frequencies. The JSD NOVEL GOLD features pure gold coils and a high density bronze matt gold-plated body.
