LOW OUTPUT MOVING IRON PICKUP CARTRIDGES
The newly redesigned Master1 and Reference1 cartridges 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 Master1 and Reference1 models use
a five piece OTL cantilever technology achieving an additional 5% tip mass
reduction over the Platinum1 and Sonata1 models. The coils are wound with
ultra-high purity long crystal (UHPLC) oxygen free copper wire. The Master1
model is mounted with Grado's specially designed nude elliptical diamond, and
the Reference1 model uses Grado's true ellipsoid design diamond.

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 Platinum model uses Grado's specially designed elliptical
diamond mounted on a brass bushing, and the Sonata model uses Grado's specially
designed nude elliptical diamond. |
