The Platinum and Sonata 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 Sonata model uses Grado's specially designed nude elliptical diamond.
"And though the Sonata showed consistent excellence with stereo staging and imaging, one always sensed a truth to the recording, without exaggerated effect."
-Wayne Garcia - The Absolute Sound
