The impossible, achieved. The Garrott P-77i is a uniquely engineered Australian MM cartridge that harmoniously combines the best characteristics of moving magnet, moving coil, and variable reluctance (Decca) designs — with a custom MicroScanner II grain-oriented parabolic diamond, dual-tube alloy cantilever, and individually fine-tuned mid-range. A cartridge that reveals the hitherto unrealised potential of your record collection.

The Impossible, Achieved

For decades, cartridge designers have faced what seemed an irreconcilable choice — the dynamic energy of moving coil, the smooth musicality of moving magnet, or the startling mid-range clarity of variable reluctance (Decca) design. Each approach brought virtues that the others could not. Each brought compromises the others avoided. The consensus was that combining the best of all three was simply not possible.

The Garrott P-77i disagrees.

Designed and individually hand-tuned by the Garrott Brothers in Australia, the P-77i is a moving magnet cartridge that achieves what the industry had considered impossible — a harmonious synthesis of all three major cartridge design philosophies. The dynamics of a moving coil without the brittle treble and listening fatigue that MC designs can introduce. The smooth, easy-listening character of the finest MM cartridges. And the realistic, clear mid-range projection for which Decca variable reluctance designs are so justifiably celebrated — without the warmth deficit that characterises that approach.

The result is a cartridge that reveals hitherto unrealised performance from your carefully preserved record collection. Previously, this level of performance has only been approached by the most expensive moving coil cartridges. The P-77i makes it accessible — without costly step-up transformers, without complex loading, and without compromise.

The MicroScanner II — Grain-Oriented Parabolic Diamond

At the heart of the P-77i is Garrott's custom-designed MicroScanner II — a gem-quality, grain-oriented parabolic diamond stylus engineered for super-accurate groove tracing and treble control. The parabolic profile provides a contact patch finely optimised for high-frequency retrieval — recovering the finest groove detail with exceptional accuracy while exerting minimal pressure on the vinyl. The grain-oriented diamond means the stylus is aligned along the crystal's hardest axis, ensuring maximum durability and consistency of performance over thousands of hours of use.

The sonic reward is immediately apparent: unusually low surface noise, an excellent signal-to-noise ratio, and a treble that is extended and accurate without the brightness or hardness that lesser stylus profiles can introduce.

Dual-Tube Alloy Cantilever — Rigidity Without Mass

The P-77i's "low Q" dual-tube alloy cantilever represents a departure from conventional single-tube cantilever design. The dual-tube configuration provides exceptional rigidity — minimising transmission losses between stylus and generator — while maintaining a low mass that allows rapid, accurate tracking across the full frequency range. This combination of rigidity and agility is essential to the P-77i's ability to extract the finest groove signals with the utmost fidelity.

Critical Acoustic Damping & Special Magnetic Circuit

The P-77i's suspension has been engineered with unusual accuracy to extract groove signals with maximum fidelity across the full dynamic range of the recording. Specially designed critical acoustic damping controls unwanted resonances — delivering the warmth and musicality of sound that distinguishes the finest cartridges from those that merely measure well.

The special magnetic circuit has been optimised to provide unusually delicate positional information — producing a "sound stage" and channel separation that reveals the spatial intent of the recording engineer with a clarity that brings the performance into the room. Channel separation of 25dB (typical at 1kHz) confirms what the ear immediately hears.

Individually Fine-Tuned Under the Microscope

Every Garrott P-77i is individually fine-tuned under Garrott microscopes — a manufacturing discipline that cannot be replicated by mass-production processes and that accounts for the mid-range sound projection that sets this cartridge apart. This is the same quality of mid-range that has made Decca variable reluctance cartridges legendary among serious listeners for decades — but delivered without the warmth deficit that limits the Decca design's musicality.

High-Output Coils — No Step-Up Required

With a 4mV output at the standard reference velocity of 3.54cm/s, the P-77i works directly with any standard MM phono stage — eliminating the need for the costly, sonically compromising step-up transformers or high-gain MC phono stages that moving coil cartridges demand. At a recommended tracking force of 1.8 grams and with a compliance of 18×10⁻⁶ cm/dyne, the P-77i is compatible with a wide range of medium-mass tonearms and will be gentle on your records.
