CAR-70

The definitive reference moving coil cartridge, engineered for absolute sonic purity.

The Kuzma CAR-70 stands as the pinnacle of contemporary phono cartridge design, representing a significant advancement in materials science and mechanical engineering. By eliminating traditional joints, it achieves a level of structural integrity that allows the stylus to track the most delicate musical nuances with profound accuracy and zero resonance.

Key Features

01

Integrated diamond assembly

Features a single-piece diamond cantilever with an integrated diamond tip, eliminating glued joints for superior rigidity and damping.

02

Sapphire housing

The entire motor assembly is encapsulated in a two-piece solid sapphire housing, providing the most neutral and rigid support structure available.

03

4N silver coil wiring

Utilises high-purity 4N silver wire for the internal coils to ensure clean, efficient signal transmission from the groove.

Engineering Philosophy

The CAR-70 was developed with a singular objective: to remove the mechanical colorations inherent in cartridge construction. By using diamond for the cantilever and sapphire for the body, Kuzma has created an exceptionally stiff and well-damped environment. This architectural approach ensures that the generator remains perfectly stable, allowing the stylus tip to retrieve information without the energy losses typically associated with conventional materials.

Build & Materials

Each component of the CAR-70 is chosen for its specific physical properties. The use of a sapphire tube to hold the coil plates creates an inert housing, while the one-piece diamond cantilever ensures that transient response is instantaneous. This combination of rare, hard materials represents an uncompromising commitment to the absolute accuracy of the phono signal.

Listening Notes

The sonic signature of the CAR-70 is defined by its transparency and expansive resolution. It excels at reproducing the acoustic space of a recording, offering a level of clarity that makes the cartridge feel absent from the signal path. Listeners will experience a profound sense of authority and ease, particularly in complex orchestral passages where timing and low-level detail are critical.
