Rega decided that the final week of 2025 needed one more plot twist. Just days after dropping the new Mercury and Solis components—and updating the more attainable Brio MK7 integrated amplifier—the company has unveiled its highest-performance moving-magnet cartridge to date: the Nd9. Borrowing the Boron rod cantilever and Fine Line stylus lineage from the reference Aphelion 2 moving coil, the Nd9 pushes MM performance into territory that usually demands far pricier hardware.
It’s also available factory-fitted on the Planar 8, giving one of Rega’s strongest turntables an even sharper edge for anyone chasing speed, accuracy, and detail without crossing fully into MC land.
Nd9 Engineering: Precision Tracking Without the Drama
Each Nd9 is hand-built by Rega’s technicians, who spend their days working with parts small enough to make the rest of us question our life choices. The cartridge uses Rega’s most advanced fine line nude diamond, bonded to a Boron rod cantilever.
The diamond’s contact radii—3 microns across the top and 30 microns vertically—let it track extremely small groove modulations with precision rather than theatrics. It’s a practical engineering choice, not magic.
Rega also reworked the generator from the ground up. The new symmetrical geometry improves channel balance, while the optimized pole gap reduces crosstalk and gives the Nd9 a wider, more consistent soundstage than previous models.
The coils are tiny parallel windings done in-house with 38-micron wire and 1,275 turns, resulting in a low-inductance, low-impedance generator that offers a cleaner, more extended high-frequency response without pushing the MM platform beyond what it actually is.
Nd9 Design: Neodymium Power, Boron Precision, and a Smarter MM Platform
Rega’s Nd series is the first moving-magnet lineup to use a Neodymium N55 magnet—the strongest commercially available. It’s normally a moving-coil trick, but here it gives the Nd9 the extra magnetic strength needed to pull off this generator design without leaning on the usual slab-of-metal MM approach. More magnetic force, less compromise.
The Nd9 uses a Boron rod cantilever paired with a fine line nude diamond stylus. The engineering challenge wasn’t the diamond—it was figuring out how to connect a Neodymium magnet to a solid Boron rod without turning the whole thing into a warranty claim. Rega solved it with help from a watchmaker who produced an ultra-fine stepped tube to marry the two materials cleanly. Boron’s low mass and high rigidity keep bending to a minimum, so groove information gets transferred without unnecessary flex or distortion.
The cartridge sits inside an injection-molded, glass-filled PPS body—rigid, low-tolerance, and lightweight. Less mass on the tonearm means less stress on the bearings, better freedom of movement, and ultimately more accurate tracking. The shape and construction borrow heavily from Rega’s MC cartridges, just executed for a moving-magnet platform.
Rega’s pivot-pad design removes the typical joint between the stylus assembly and cartridge body, which is good for tracking stability and consistency over time. If you wear out or damage your Nd9, Rega’s rebuild program replaces the cantilever, stylus, and pivot pad, then tests the cartridge as if it were new. The price lands roughly where a replacement stylus would on other brands—just without the “let’s hope the old body still works” gamble.

The Bottom Line
Rega ends 2025 with a moving-magnet cartridge that doesn’t behave like one. At £695 UK SSP, the Nd9 brings together a Boron rod cantilever, a fine line nude diamond, an N55 Neodymium magnet, and a newly engineered low-inductance generator—features normally reserved for MC designs or far pricier MM outliers. The glass-filled PPS body keeps mass low and rigidity high, the three-point mount keeps setup straightforward, and Rega’s rebuild program gives owners a practical long-term upgrade path.
We’re still waiting on official U.S. and Canadian pricing, but when it lands, the Nd9 will be stepping directly into the same ring as the Dynavector 10×5 MKII, Ortofon 2M Black, and Hana SL II—cartridges that have defined their price class for years. If Rega’s engineering claims translate into the kind of real-world performance they’re known for, the Nd9 could make that bracket a lot more interesting.
