Rega Planar 3 Turntable
The Rega Planar 3 Turntable arrives as a complete deck minus two things many rivals bundle in: a cartridge and a power supply. That's a deliberate split in Rega's range, aimed at buyers who already have a moving magnet or moving coil cartridge they want to carry over, or who'd rather choose their own from Rega's cartridge line-up instead of accepting whatever's fitted at the factory. It also suits anyone happy running the deck at its standard fixed speed for now, with the option of adding Rega's Neo power supply later rather than paying for it upfront. Two years of redevelopment under Roy Gandy went into this version of the Planar 3, and only two parts survive from the outgoing RP3, so it's worth treating as a new design rather than a cosmetic update.
What do you get when the Planar 3 ships without a cartridge?
This Planar 3 Turntable comes with the RB330 tonearm pre-mounted but no cartridge attached, which means setup includes fitting and aligning a cartridge yourself, or via your dealer, before first use. The arm uses Rega's three-point mounting system, common across the brand's Nd-series and Ania cartridges, so compatible options bolt straight on without adapter plates. Buying the deck this way costs you the alignment step that a factory-fitted cartridge skips, but it opens the door to mounting a higher-spec cartridge than Rega offers as a factory option, or reusing one from a previous turntable, as long as it suits the RB330's mounting geometry and tracking range.
How does the Rega Planar 3 turntable's plinth cut resonance without adding weight?
Rega built the Planar 3 around an acrylic laminated plinth reinforced by a double brace system rather than the full phenolic skin used on earlier Planar models. The braces sit between the tonearm mount and the main hub bearing, exactly where rigidity matters most for keeping the arm and bearing in a fixed relationship to each other. A 3mm phenolic bottom brace pairs with a metalised-skin phenolic top brace, giving Rega double-thickness resin only in that zone instead of across the whole chassis. The payoff is twofold: a stiffer structure resists flexing under stylus tracking forces, which would otherwise smear fine detail through unwanted movement, and the reduced overall mass means less motor or bearing noise gets carried into the spinning record. New isolation feet beneath the plinth add a further layer of vibration control by reducing what transfers up from the supporting shelf or rack.
What engineering went into the RB330 tonearm fitted as standard?
The RB330 tonearm fitted to this Planar 3 draws on more than 35 years of Rega tonearm development, built using 3D CAD and CAM tools rather than carried over from older arm tooling. Its tube redistributes mass along its length to cut down on the points where resonance can build up and feed back into the signal, while a new bearing housing delivers smoother, lower-friction movement than previous RB-series arms. That low friction matters once a cartridge is fitted, since it lets the stylus follow the groove with minimal resistance rather than dragging against arm friction, which would otherwise mask fine groove detail regardless of cartridge quality.
Which cartridges can you mount on the Planar 3's tonearm?
Rega's own Nd3, Nd5 and Nd7 moving magnet cartridges are built specifically for the three-point mount used on the RB330, each pairing a neodymium magnet generator with a glass-filled PPS body and aluminium cantilever, differing mainly in stylus profile, from the Nd3's bonded elliptical tip through to the Nd7's fine line nude diamond. All three are specified to track at 1.75g. Choosing between them, or fitting a separate moving coil cartridge compatible with the mount, is the main decision left open by buying the Planar 3 without a cartridge fitted, and it lets you match cartridge spend to your existing phono stage and amplifier rather than accepting a fixed factory pairing.
How does the platter and motor assembly support accurate, stable rotation?
A 12mm float glass platter with a polished Optiwhite edge sits on a redesigned sub platter built for improved stiffness and rotational accuracy. Drive comes from a 24V low noise motor housed in a new cover tray with integrated cooling, turning the platter via Rega's Advanced EBLT belt, standard fitment since March 2021. The redesigned brass main hub bearing improves the fit between bearing and plinth, cutting the stress that uneven fit would otherwise place on the bearing during continuous rotation. Glass's density and rigidity help it resist the kind of flex a lighter platter material might show under stylus drag, which keeps rotational speed steadier through a side's playback.
Does the Planar 3 need the Neo power supply to work?
No. The Planar 3 Turntable runs without the Neo PSU, using its own onboard 24V motor control as standard, with a fixed-speed belt drive rather than electronic switching between speeds. The motor control PCB integrates a mini DIN connection ready for the Neo PSU, sold separately, so adding it later is a plug-in upgrade rather than a modification. Fitting the Neo brings electronic speed change and an additional anti-vibration circuit to the motor supply, useful for anyone who finds themselves swapping between 33 and 45rpm records often enough to want it done at the press of a button rather than by moving the belt manually.
What's involved in getting this Planar 3 running at home?
Rega includes a multi-lingual quick start guide with every Planar 3, covering platter and belt fitting, levelling the plinth and connecting the RCA phono leads to your amplifier or separate phono stage. Because this version has no cartridge pre-fitted, you'll also need to mount and align one before playback, using the RB330's three-point mounting system and setting tracking force to suit whichever cartridge you choose. The plinth's power switch sits in an ergonomic position for everyday use, and a clear dust cover is supplied as standard to protect the plinth and platter between sessions.
How does buying the Planar 3 without cartridge and PSU change its position in Rega's range?
Selling the Planar 3 Turntable without a cartridge or power supply puts the buying decision on you rather than Rega: which cartridge suits your phono stage, and whether electronic speed change matters enough to add the Neo PSU now or later. Compared with the Planar 1 and Planar 2 below it, the Planar 3 already brings the RB330 tonearm, double brace plinth and glass platter as standard, so the gap between those models and this one is about plinth and arm engineering rather than what's bundled in the box. Compared with the Planar 6 and Planar 8 above it, choosing this Planar 3 and adding cartridge and PSU separately can land at a similar specification for less outlay, provided you're comfortable handling cartridge alignment yourself. It also suits buyers upgrading from an older Rega deck who already own a compatible cartridge and don't want to pay twice for one. All four finishes, gloss white, gloss black and light oak effect, share identical plinth, tonearm and motor specifications, so the decision between them comes down to appearance rather than performance. The deck is also compatible with Rega's wall bracket, shared with the Planar 1, Planar 2 and Planar 6, for anyone planning a wall-mounted rather than shelf-based setup. Every Planar 3 carries Rega's lifetime warranty against manufacturing defects, which doesn't cover wear items or consumables such as the drive belt or stylus.
