The Reference top notch phpno cartridge high output moving iron

 

I
have Grado The Reference phono cartridge for sale. The cartridge is in very
good operational and cosmetic condition. Everything is original. The cantilever
is straight. The stylus is in perfect order. It has about 150 hours of usage.

The
cartridge comes with the original Grado box, stylus guard and mounting
screws. 

 

Grado's
The Reference is the flagship high-output wood-body phono cartridge. If your
system is set up for moving magnet , moving iron or high-output moving coils cartridges,
The Reference is among the best cartridges available to you. Gorgeously
hand-crafted from carefully selected Mahogany, it'll offer a fresh listening
experience for even your most frequently played recordings.

Optimized Transmission Line (OTL) Cantilever/Stylus
Assembly

Grado's OTL provides an ideal transfer of the signal from point to point, e.g.,
stylus to cantilever to magnet to coils, etc. This has been achieved by
eliminating resonance at each of these key junctions. The transmission line
cantilever consists of separate sections that are telescoped into each other.
All sections are made of different alloys, some sections hollow, other sections
solid. These sections are bonded together with materials that act as dampers,
and are coated with a black proprietary material which controls and absorbs
resonances that travel on the surface of the cantilever (known as skin
effects). The OTL stylus/cantilever design will make your records sound
quieter, improve the height, width, and depth of the soundstage, and offer more
detail than previously obtainable. Cartridge Holography does exist...and that
is what Grado's OTL technology is all about, more performance.



Pivoted-Fixed Axial Cantilever/Stylus
Generator

This design feature is basically quite simple. The "OTL" cantilever
shaft is brought to a fixed axial pivot that supports the entire cantilever
assembly. A miniature element attached to the end of the cantilever is allowed
to move freely within the lines of flux of a stationary magnet and coil
structure. This system of support is mechanically more accurate (more linear)
than conventional "teeter-totter" designs that utilize an iron
armature to balance the mass of the cantilever. The teeter-totter design is
supported in the center with a rubber donut mounting. The fixed axial design
has a very low tip mass, which results in lower distortion, improved transient
response, and longer record life.



Flux-Bridger Generator System

The Flux-Bridger design uses four separate magnetic gaps that the miniature
element of the cantilever bridges. The miniature element moves between opposing
flux gaps creating an increase in flux in one gap while reducing it in the
other. The four separate magnetic gaps create a highly efficient and perfectly
balanced system. This design requires fewer coil turns than conventional
designs.

 

The
cartridge is in perfect operational and cosmetic condition. It has 120 hours of
ply time. The cantilever is true and straight, the stylys is Mint.
