Grado Reference 1 Phono Cartridge
The top of the Reference line uses an exotic five-piece cantilever design and a true ellipsoid diamond stylus. The entire assembly is painstakingly assembled and tuned to one resonance point. The end result is one of the finest-sounding cartridges available of any type.
The newly redesigned Grado Reference 1 cartridge offers four improvements over its predecessor.
- The coil design has been reconfigured. The size of the coils were reduced, cutting back on the number of turns, for improved sound quality.
- Grado Labs has developed a new process of potting the coils which helps control internal resonance in the coils which then lowers the noise floor even more than before.
- Also, the effective moving mass of their generating system has been reduced by 17%, thus allowing for a quicker and more accurate reproduction of music.
- All this is hand-assembled within a machined, new processed, Australian Jarrah wood housing. The wood enclosure has been changed from Mahogany to Australian Jarrah, which is a much harder and denser, thus adding greater stability to the cartridge as a generating device.
The Grado Reference 1 and Reference Master 1 models use a five piece OTL cantilever technology achieving an additional 5% tip mass reduction over the Grado Reference Platinum1 and Sonata1 models. The coils are wound with ultra-high purity long crystal (UHPLC) oxygen free copper wire. The Grado Reference Master1 cartridge is mounted with Grado's specially designed nude elliptical diamond, and the Grado Reference 1 Reference1 model uses Grado's true ellipsoid design diamond.

Stereophile Vol.21, No.12
"The Reference is the finest fixed-coil cartridge I've ever heard, and one of the finest sounding cartridges I've ever heard in the midrange regardless of price."
Stereophile / Michael Fremer Vol.21, No.3
"It is a great bargain, and I would take it over any number of cartridges I have heard that sell up to five times its price."
The Absolute Sound / Adam Walinsky
"The Reference sets a benchmark for analog cartridge performance and is a real alternative to the analytical school of sound. If you think moving coil cartridges are the only way to go, think again. You owe it to yourself to listen to Grado's The Reference."
