The Platinum2 and Sonata2 models use a modified four piece OTL cantilever technology achieving a 10% tip mass reduction over the Prestige series and ultra-high purity long crystal (UHPLC) oxygen free copper wire in the coils. The Platinum2 model uses Grado's specially designed elliptical diamond mounted on a brass bushing, and the Sonata2 model uses Grado's specially designed nude elliptical diamond.
"Since we have considerably fewer turns in the Statement Series we can use a much larger size wire, thus knocking resistance from 470 ohms to 2 ohms in the Statement Series. This new wire has over 16 times more area for carrying the signal: this also shortens the distance the signal must travel from 125ft to a little over 7ft. In the Statement series we have also shortened the magnetic gap, increasing the flux density."
