Ortofon Plattenstabilisator Heavy 350 g, Silver

The Ortofon Plattenstabilisator Heavy (350 g, Silver) is the weight for high-end and direct-drive turntables with a robust motor — more mass, more calm, more of what's in the groove.

Why the Plattenstabilisator Heavy 350 g?

350 g couples the record firmly to the platter, so vibrations from the motor, the room and the speakers find less of a path to the stylus. At the same time, the extra mass increases the moment of inertia — the platter spins more stably and reacts less to micro-disturbances. The felt underside protects the record, the Ortofon wave-pattern grip sits securely in your hand.

What you get

More control in the bass and an audibly calmer reproduction, especially on high-mass direct-drive turntables: less rumble, more defined low mids, a clearly defined bass range. Place it, remove the stylus, play — the upgrade is done in ten seconds, no tools required. The satin matte silver anodizing suits light-colored turntables and silver equipment fronts.

Who is the Heavy 350 g for — and who isn't it for?

Ideal for high-end, premium and direct-drive turntables with a robust motor and heavy platter. Bottom line: leave light belt-drive turntables (Rega Planar, Pro-Ject Debut & co.) alone and reach for the 240 g standard version instead — 350 g would overload such motors in the long run. And strongly warped records won't be flattened by this weight either — for that you need a real clamp with a counter-plate.

Our verdict

The right weight for heavy, robust turntables: more calm, more control, no effort. Out of place on entry-level decks, a worthwhile fine-tuning tweak on direct-drive turntables.

Frequently asked questions

Does the 350 g Plattenstabilisator also work on my Thorens TD-1500 or TD-1600?

Yes — the TD-1500 and TD-1600 have a robust belt drive with a heavy platter and are designed for this weight. For older, lighter Thorens models like the TD-160, it's best to check with us first.

Silver or black — is there a sonic difference?

No, not a single decibel. The choice is purely aesthetic: silver suits light-colored turntables and silver fronts, black suits dark equipment and modern setups. We keep both versions in stock.

How do I place the 350 g weight correctly?

Guide it calmly over the spindle and set it gently down on the record — don't drop it. Wait until the platter has stopped before placing or removing it. This protects the spindle and bearing, and the felt sits cleanly on the label rather than the groove.
