Rega Nd7 Moving Magnet Cartridge

Why choose the Rega Nd7 over a conventional moving magnet cartridge?

Rega Nd7 is a moving magnet cartridge designed around a neodymium magnet generator rather than the more common bar magnet arrangement used in many moving magnet designs. Rega states that the Nd7 is the first moving magnet cartridge to use an N55 neodymium magnet, allowing the generator to operate with a substantially more powerful magnetic field while retaining the output characteristics associated with moving magnet cartridges.

The cartridge forms part of Rega’s Nd series and was developed to push moving magnet technology beyond the performance limits traditionally associated with the category. The design combines a new generator architecture, low-inductance coil arrangement and a fine line nude diamond stylus profile to focus on accurate groove tracing, channel balance and high-frequency response.

Is the Rega Nd7 suitable for moving magnet phono stages?

Rega Nd7 is a high-output moving magnet cartridge with a nominal output voltage of 5–6mV, making it suitable for moving magnet phono inputs and dedicated MM phono stages.

This output level allows the cartridge to work with equipment designed for moving magnet operation, including products such as the Rega Fono MM phono stage and integrated amplifiers that incorporate a moving magnet phono input.

What makes the stylus assembly different?

Rega Nd7 is fitted with a fine line nude diamond stylus mounted on an aluminium cantilever. The fine line profile is one of the cartridge's key differentiators because its small contact geometry enables the stylus to follow subtle groove variations more precisely than simpler stylus shapes.

Rega uses the same stylus profile found on its higher-range Apheta 3 and Aphelion 2 moving coil cartridges. The profile is intended to maintain close contact with the groove walls, helping the cartridge retrieve low-level information recorded in the vinyl while supporting accurate tracking.

How does the generator design affect cartridge performance?

Rega Nd7 is built around a newly developed generator geometry that uses symmetrical construction and miniaturised parallel coils. Rega designed this arrangement to improve channel balance while reducing inductance and impedance within the generator system.

The lower inductance generator contributes to improved high-frequency behaviour, while the optimised pole gap is intended to improve linearity and crosstalk characteristics. These engineering changes target measurable cartridge behaviour rather than relying solely on stylus profile improvements.

Which turntables is the Rega Nd7 designed to complement?

Rega Nd7 is available as a factory-fitted cartridge option on the Rega Planar 6 and Rega Planar 8 turntables. Rega specifically identifies these turntable platforms as intended partners for the cartridge.

The cartridge can therefore appeal to buyers building a Rega analogue playback system around those decks, particularly where a moving magnet front end is preferred. Rega also highlights the cartridge as a complementary match for the RB330 and RB880 tonearms fitted to those turntable models.

How straightforward is installation?

Rega Nd7 is equipped with Rega’s three-point mounting system. This fixing arrangement is designed to simplify cartridge installation on compatible Rega tonearms by providing a predefined mounting geometry.

The cartridge is specified for a tracking force of 1.75g, providing a clear setup target during installation and alignment.

What materials are used in the cartridge body?

Rega Nd7 is housed in a glass-filled polyphenylene sulphide (PPS) body produced to tight tolerances. Rega selected this material because it combines low mass with high rigidity, two characteristics that influence how the cartridge interacts mechanically with the tonearm.

A lightweight cartridge body places less load on tonearm bearings, while the rigid structure helps maintain stability between the generator assembly and the record groove during playback. Rega notes that the body design takes inspiration from the company's moving coil cartridge range.
