SUPREMETECH Acrylic Platter for Rega & NAD 533 Turntables — 15mm Height, 300mm Diameter for Matless Playback

SUPREMETECH's 15mm acrylic platter is a precision replacement platter designed to improve rotational stability and reveal more surface detail on compatible Rega and NAD 533 turntables.

Many stock platters on entry-level turntables are light or made from materials that limit rotational inertia and dampening. This SUPREMETECH acrylic upgrade swaps the original platter for a dense, low-stiffness disc engineered to increase mass, reduce wow and flutter, and produce cleaner, quieter playback when used without a mat. It also offers an attractive, low-profile look that pairs well with illuminated setups and high-contrast tonearm assemblies.

How does the acrylic platter affect turntable rotational stability?

The added mass of acrylic raises the platter's rotational inertia, helping the platter maintain steady speed during playback and reducing small speed variations. That steadier rotation can make pitch more consistent across a record side.

• Higher mass increases inertia for smoother rotation.
• Precision center hole (18mm) and carved recess maintain fit with Rega/NAD spindles.
• Dimensions optimized for 300mm diameter platters common on Rega models.

Will I need a mat with this acrylic platter, and how should I place records?

This 15mm version was designed primarily for matless use: records are intended to sit directly on the acrylic surface to take advantage of its material properties. If you prefer an additional mat, consider the 12mm variant which accommodates a mat more easily.

• Recommended use: record directly on acrylic for best material coupling.
• If you want a mat, compare the 12mm model to allow proper platter clearance.
• Place the record concentrically on the platter to avoid off-center wobble.

Is this platter compatible with my Rega or NAD 533 turntable?

The SUPREMETECH acrylic platter is sized and machined for a direct fit with many Rega Planar models (Planar 1/2/3, RP1/RP3, P1/P2/P3/P3-24) and the NAD 533. Check spindle and sub-platter clearances against the supplied dimensions before ordering.

• Diameter: 11.8 inches (300 mm) to match common Rega platter footprints.
• Center hole: 0.71 inches (18 mm) to fit standard Rega/NAD spindles.
• Underside carved recess: 7.13" diameter by 0.39" depth for clearance above sub-platter.

What are the physical specs and installation considerations?

The platter measures 300 mm across, is 22 mm thick, and weighs approximately 1615 grams. The effective height of this upgrade is 15 mm—this is the taller version intended for matless playback. Installation is straightforward but verify clearance and tonearm geometry after fitting.

• Thickness: 0.87 inches (22 mm); Weight: 3 lb 9 oz (1615 g).
• Effective height: 15 mm (select the 12 mm model if you need mat clearance).
• After mounting, confirm platter runs true and the tonearm tracks correctly across the record.

Who is this for: This SUPREMETECH acrylic platter upgrade is aimed at vinyl listeners who want a simple mechanical improvement—more inertia and cleaner surface coupling—on Rega Planar series turntables and the NAD 533. It's suited to users comfortable checking clearances and preferring matless playback to exploit acrylic's material characteristics, as well as to anyone seeking a visually cleaner, illuminated-friendly platter for their system.
