Rega Nd5 Moving Magnet Cartridge
The Rega Nd5 is a moving magnet cartridge built for vinyl listeners who want to extend what a moving magnet design can deliver, rather than step up to moving coil. Rega developed the Nd5 over ten years and built it around a Neodymium magnet, a component normally reserved for the company's moving coil range. That choice, combined with a new generator geometry and an in-house wound coil assembly, positions the Nd5 as a step-up cartridge for owners of Rega turntables who want measurable gains in channel balance, crosstalk and high-frequency response without changing phono stage or tonearm.
Why the Rega Nd5 Suits a Cartridge Upgrade
What sets the Nd5 apart from other moving magnet cartridges?
The Nd5 is, according to Rega, the first moving magnet cartridge to use a Neodymium N55 magnet, a magnet type the company already uses in its own moving coil designs and one it describes as the most powerful commercially available grade. That extra magnetic power lets Rega's engineers work with a generator geometry built around perfect symmetry, which keeps the two channels balanced more accurately than a standard bar magnet allows. The Nd5 also uses an optimised pole gap, and narrowing this gap tightens control over linearity and crosstalk, which in turn widens the reproduced soundstage compared with Rega's earlier moving magnet models. The coil assembly reinforces this: Rega winds miniaturised parallel coils in house from 38-micron wire, using 1275 turns per coil. Fewer turns of finer wire lowers both inductance and impedance in the generator, and a lower-impedance generator extends high-frequency response further than a conventional moving magnet coil winding would.
Which turntables and tonearms suit this cartridge?
The Nd5 is offered as a factory-fitted option on Rega's Planar 3 and Planar 6 turntables, both of which carry the RB330 tonearm as standard. Buying the cartridge as part of a factory-fitted package costs less than purchasing the Nd5 separately and fitting it afterwards, since Rega aligns and sets up the cartridge on the tonearm before the turntable leaves the factory. On the output side, the Nd5's nominal output voltage of 5 to 6mV matches it to dedicated moving magnet phono stages such as Rega's Fono Mini A2D or Fono MM, both of which are built specifically for moving magnet cartridges rather than offering switchable moving coil gain.
How is the Nd5 fitted and aligned on a tonearm?
The Nd5 is fitted using Rega's 3-point mounting system rather than the two-screw slotted fixing found on many generic cartridges, and this fixing pattern is designed to locate the cartridge against a tonearm headshell with matching mounting points. Rega recommends a tracking pressure of 1.75g, which sets the downforce the stylus exerts on the record groove and needs to be set on the tonearm counterweight during installation. Full mounting and alignment instructions are available as a separate downloadable PDF from Rega for owners fitting the cartridge themselves rather than buying it as a factory-fitted package.
What happens if the stylus wears or gets damaged?
The Nd5 is built around Rega's pivot pad design, which removes the mechanical joint that normally sits between the stylus housing and the cartridge body on conventional cartridges. Removing that joint improves tracking stability, since there's no separate jointed connection for the stylus assembly to flex against during play. If the stylus wears down or the cantilever gets damaged, owners return the cartridge to a Rega dealer through the Rega rebuild scheme rather than buying a new cartridge outright. The dealer supplies a rebuilt cartridge fitted with a new cantilever, stylus and pivot pad, tested to the same standard as a new Nd5, at a reduced price once the worn cartridge is traded in, working out at roughly the cost other manufacturers charge for a standalone replacement stylus. Every Nd5 also carries Rega's lifetime warranty against manufacturing defects, separate from the rebuild scheme's cover for wear.
How does the stylus profile affect tracking accuracy?
The Nd5 is fitted with an aluminium cantilever carrying a perfect elliptical nude diamond stylus. Rega forms this profile through an elliptical grinding process applied to polycrystalline manmade diamond, producing a true ellipse rather than an approximated one. The shape of that contact point determines how closely the stylus can follow the groove modulations cut into the vinyl, and a true elliptical profile holds contact with more of the groove wall through fast or complex passages than a simpler conical profile, which is what lets it pull more detail from the record surface.
Why does the Nd5's body material matter for tonearm performance?
The Nd5 is housed in a glass-filled polyphenylene sulphide body, known as PPS, made through a zero-tolerance injection moulding process that Rega also uses for its moving coil range. PPS is both lightweight and highly rigid, and that combination matters because a heavier cartridge body adds mass the tonearm bearings have to support and move during play. Reducing that mass lets the tonearm respond more freely to groove modulations, which is a precondition for accurate tracking regardless of which generator or stylus sits inside the body. Rega supplies the Nd5, along with the rest of the Nd range, in 100% recyclable packaging.
