Rega Nd7: Moving Magnet Cartridge

The Rega Nd7 is a moving magnet cartridge developed over ten years, and it represents something genuinely new in the technology. Where conventional moving magnet designs use standard magnets, the Nd range — patent pending — is the world's first to employ ultra-high powered Neodymium magnets in a moving magnet configuration. That single engineering decision unlocks a generator geometry that simply wasn't possible before, and everything else in the Nd7 follows from it.

Fine Line Nude Diamond

Each Nd7 is hand-made by Rega's technicians in Southend-on-Sea. The stylus is a fine line nude diamond — the same profile Rega fit to their high-end moving coil cartridges, the Apheta 3 and Aphelion 2. The diamond is Monocrystalline and manmade, with a minor radius of just 3µm as viewed from the top and 30µm in the vertical. That exceptionally small contact area means the stylus responds immediately to the finest groove modulations, retrieving detail that a larger-radius profile would simply pass over.

Generator Design

The Nd7 uses a completely new generator geometry built around perfect symmetry, which produces highly accurate channel balance. The pole gap has been optimised for superior linearity and crosstalk characteristics — giving a far wider stereo image than previous models. The coils themselves are miniaturised and parallel-wound in-house using 38-micron wire with 1,275 turns. This produces a low inductance, low impedance generator with vastly improved high frequency response compared to conventional moving magnet designs.

The cantilever is aluminium, and the body is made from highly rigid, lightweight PPS — chosen to minimise resonance and keep the generator isolated from external vibration. Mounting uses Rega's 3-point system, which simplifies alignment on any Rega tonearm and ensures consistent geometry. The Nd7 is available factory-fitted on the Planar 6 and Planar 8 turntables, and carries a lifetime warranty against manufacturing defects.

Sustainability

In keeping with Rega's broader commitments, the Nd range is supplied in 100% recyclable packaging.
