Pandora Minor

Overview

The Aries Cerat Pandora Minor is an ultra-high-end direct-drive turntable developed by the Cyprus-based Aries Cerat and publicly shown at the 2026 Vienna high-end event. It is the smaller sibling of the full-size Pandora, but it retains the same unusual engineering concept: a very high-inertia platter/motor assembly supported by a large, self-aligning hydrodynamic oil bearing rather than conventional mechanical bearings. Its reported European price is approximately €150,000.

The design is less an incremental refinement of a conventional record player than an attempt to eliminate several traditional turntable error mechanisms, motor cogging, bearing friction, platter eccentricity, and tonearm tracking-angle variation.

Drive system

The Pandora Minor uses a direct-drive motor integrated with the platter:

• The motor has no conventional iron armature.

• Its windings are distributed around the permanent-magnet structure rather than concentrated around discrete stator poles.

• The resulting motor is intended to avoid distinct magnetic poles and the associated torque ripple or cogging.

• Aries Cerat describes the arrangement as a “wave-drive” motor.

This is significant because direct drive normally offers excellent long-term speed stability but can introduce very small periodic torque variations if the motor has conventional pole and commutation geometry. By eliminating the iron armature and distributing the windings, Aries Cerat is attempting to obtain direct-drive speed control without the usual cogging compromises.

The available technical material does not publish conventional specifications such as wow-and-flutter, absolute speed accuracy, rumble, motor-control resolution, or startup time. Those omissions matter. The architecture is highly unusual, but independent measurements would be needed to establish whether it outperforms well-engineered conventional direct-drive systems.

Platter and inertia

The platter is approximately 390 mm in diameter, larger than the nominal 300–305 mm record diameter. Its mass is concentrated toward the outside, increasing rotational inertia more efficiently than simply adding mass near the spindle.

Aries Cerat states that its rotational moment of inertia is equivalent to approximately 200 kg applied to a 300 mm platter. That is not the same as saying that the platter weighs 200 kg; it is an inertia comparison intended to describe resistance to short-term speed disturbance.

High inertia can help reject:

• Small instantaneous motor-speed variations.

• Stylus-drag modulation caused by heavily modulated grooves.

• Speed perturbations from record eccentricity.

• Torque fluctuations from the drive electronics.

The trade-offs are equally important. A high-inertia platter requires substantial starting torque, careful acceleration control, a very rigid structure, and a bearing capable of handling both static and dynamic loads without introducing low-frequency movement.

Hydrodynamic bearing

The most distinctive part of the design is the platter support. The rotating platter/motor assembly rests on a large hydrodynamic oil bearing with a reported diameter of approximately 280 mm.

Its operating principle is:

1. At rest, the rotating assembly is supported mechanically by the bearing surfaces and oil.

2. As the assembly reaches operating speed, hydrodynamic pressure develops in the oil film.

3. The rotating assembly rises by approximately 0.5 mm.

4. In operation, the platter is therefore separated from the stationary structure by a pressurized oil film.

5. The bearing is described as self-aligning, removing the need for a conventional centering bushing.

The manufacturer and show demonstrator describe the result as essentially no mechanical contact between the spinning and stationary assemblies during operation. HiFi Pig gives the related description that the roughly 100 kg platter in the larger Pandora “aquaplanes” on the oil film above about 2 rpm.

This approach should, in principle, provide:

• Very low rotational friction.

• No rolling-bearing noise.

• High radial stability.

• Excellent resistance to spindle tilt and lateral motion.

• A potentially very low mechanical-noise floor.

However, it also introduces practical engineering questions:

• Oil viscosity changes with temperature.

• The bearing must remain correctly filled and uncontaminated.

• Startup and shutdown are mechanically more demanding than normal platter bearings.

• Long-term oil maintenance and servicing become important.

• Installation must likely be extremely level and stable.

• The bearing’s low-frequency behavior under stylus-generated forces requires measurement.

The hydrodynamic bearing should therefore be understood as a sophisticated precision system, not as a maintenance-free “frictionless” bearing.

Tonearm architecture

The Pandora Minor is shown with Aries Cerat’s own linear-tracking air-bearing tonearm. The tonearms are interchangeable with those used on the larger Pandora.

The reported characteristics include:

• Linear tracking rather than pivoted-arm geometry.

• A high-pressure, close-tolerance air bearing.

• Zero or near-zero friction in the tracking direction.

• Very low mechanical play.

• High resistance to tilt and azimuth movement.

• Multiple arm construction options, including titanium, hybrid aluminium/carbon, and titanium/carbon versions.

A linear tracker is intended to keep the cartridge tangent to the record groove, avoiding the tracking-angle error that occurs as a conventional pivoted arm sweeps across the disc. The theoretical advantage is reduced skating-force requirement and more consistent groove geometry from outer to inner grooves.

The engineering challenge is maintaining stiffness and low resonance while allowing perfectly straight, low-friction lateral movement. Aries Cerat specifically claims that its air bearing avoids the looseness and weak bass sometimes associated with linear arms.As with the drive system, the publicly available information does not provide key measurements such as effective mass, horizontal and vertical compliance, bearing clearance, resonance frequency, tracking accuracy, air consumption, or required compressor specifications.

System configuration

The Pandora Minor is not a turntable with a permanently fixed arm and cartridge. It is intended as a modular analogue front end:

• Aries Cerat tonearms can be exchanged.

• Multiple tonearms are possible on the wider platform, subject to the final mounting arrangement.

• Cartridge choice remains separate from the turntable.

• The turntable output was demonstrated through the Aries Cerat Hermes phono stage.

The 2026 Vienna demonstration used the Pandora family in an Aries Cerat system with the Hermes phono stage, indicating that the turntable is designed to operate as part of the company’s complete analogue chain rather than as a mass-market standalone product.

Bottom line

The Pandora Minor’s core innovation is the combination of a cogging-resistant ironless direct-drive motor, an extremely high-inertia 390 mm platter, and a large self-aligning hydrodynamic oil bearing. Its linear-tracking air-bearing tonearm addresses the other major geometric limitation of analogue playback: changing cartridge alignment across the record surface.

It is best viewed as a no-compromise engineering demonstrator and bespoke reference source rather than a conventional high-end turntable. The architecture is genuinely distinctive; whether its audible and measured performance justifies its approximately €150,000 price will depend on independent test data that, as of 28 August 2026, has not yet been published.
