The newly redesigned Platinum1 and Sonata1 have had their coil design
reconfigured, and the effective moving mass of their generating system
has been reduced by 17%. All this is hand-assembled within a machined,
new processed, Australian Jarrah wood housing. The Platinum1 and Sonata1
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 Platinum1
model uses Grado's specially designed elliptical diamond mounted on a
brass bushing, and the Sonata1 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 | | "…the Sonata does a great job in reproducing the bass…Yes, the midrange was excellent. The upper octaves of the Grado Sonata did extend to the limits of my test records and sound very smooth. Very nice indeed!"
- Anthony H. Cordesman - Audiophile Voice | |
