Rega Nd9 Neodymium Moving Magnet Cartridge
Rega’s Reference Moving Magnet Cartridge
The Rega Nd9 sits at the top of the Nd range and is the highest-performing Moving Magnet cartridge Rega has produced. It shares the Neodymium N55 magnet and generator of the Nd3, Nd5 and Nd7, and adds a Boron rod cantilever with a Fine Line stylus profile taken from Rega’s reference Aphelion 2 Moving Coil cartridge. Each Nd9 is hand-made at Rega’s factory in England.
Boron Cantilever and Fine Line Nude Diamond Stylus
The step up from the Nd7 is the cantilever. Boron is very light and very stiff for its mass, so it reacts faster to changes in the groove and bends less, passing on the stylus movement more accurately and with less distortion than aluminium. Joining the Nd magnet to a solid Boron rod took Rega a new part: an ultra-fine connecting tube, made with a well-known watchmaker, with a different diameter at each end. The Fine Line nude diamond bonded to the cantilever has a minor radius of just 3 microns viewed from above and 30 microns viewed from the front. That small contact area lets the stylus follow very fine changes in the groove and recover more detail from the record.
Neodymium Magnet and Generator Design
The Nd range was the first Moving Magnet design to use a Neodymium N55 magnet, the most powerful commercially available magnet, which gives more output than a standard bar magnet. The generator geometry is fully symmetrical for accurate channel balance, and an optimised pole gap improves linearity and crosstalk for a wider soundstage. The miniaturised parallel coils are wound in-house with 38-micron wire and 1,275 turns, giving a low-inductance, low-impedance generator with much improved high-frequency response. Output is 5 to 6mV, so the Nd9 works with any standard Moving Magnet phono stage.
Glass-Filled PPS Body and Pivot Pad Design
The assembly is housed in a zero-tolerance injection-moulded body made from glass-filled polyphenylene sulphide (PPS), a light and highly rigid material. The low-mass body reduces stress on the tonearm bearings and helps the arm move freely. Rega’s pivot pad design removes the mechanical joint between the stylus housing and the main body, which improves tracking and keeps the stylus stable across the record. The Nd9 uses Rega’s three-point fixing, so it aligns itself on a Rega tonearm.
Factory Fitted Option and the Rega Rebuild Scheme
The Nd9 is available factory fitted to the Rega Planar 8 turntable, at a lower price than buying the two separately. Ask us for details. If your Nd9 is ever worn or damaged, it can be traded in through a Rega dealer for a fully tested rebuild cartridge with a new cantilever, stylus and pivot pad, at a cost similar to a replacement stylus from other makers. The Nd9 comes in 100% recyclable packaging and carries a lifetime warranty against manufacturing defects.
