Grado Master4

The moving iron architecture allows for a significantly lower moving mass compared to traditional moving magnet designs. This reduction in mass helps the stylus track grooves with greater agility and stability, resulting in a more precise and detailed sound.

The Osage wood housing is specifically chosen for its acoustic properties, which help dampen unwanted resonance and vibration. By controlling these resonances, the cartridge maintains a more natural, balanced tonal character without coloring the music.

The Master4 is available in both high and low output versions, so you should choose the one that matches your phono stage's gain capabilities. It is compatible with standard input loads between 10k and 47k ohms, making it versatile for most high-quality turntable setups.

Boron is an exceptionally stiff and lightweight material, which allows the cantilever to respond instantly to the nuances in the record groove. This speed and responsiveness are critical for retrieving fine details and maintaining harmonic integrity during playback.

With a weight of 9.6 grams and a compliance of 20μm/mN, the Master4 is designed to work well with a wide range of modern tonearms. It is best suited for medium-mass tonearms, but you should always verify your tonearm's effective mass to ensure a proper match.

The cryogenic treatment process is used to relieve internal stresses within the cartridge's components, particularly the internal wiring and signal path. This helps reduce resonance and improves the overall consistency and clarity of the signal transmission.
