Nobsound STB-02 Aluminum Record Weight Clamp and Turntable Disc Stabilizer

Our verdict

The STB-02 is a $29.99 record weight for vinyl listeners who want records sitting flatter and spinning more calmly. The 460g non-magnetic aluminum body reduces resonance and vibration, which Douk Audio says sharpens mid-range vibrancy and vocal realism, and it ships with a soft base pad and a protective carry case. Two things to check: the title and spec sheet disagree on weight (420g versus 460g), and the 40mm height needs clearance under your dust cover.

Best for
Vinyl listeners who want a low-cost record weight to flatten LPs and damp resonance without risking magnetized parts.
Skip if
Your turntable has a low closed dust cover, or its suspension isn't designed to spin an extra 460g.

The Nobsound STB-02 is an aluminum record clamp and disc stabilizer priced at $29.99, sold in black or red. It is a disc of non-magnetic aluminum 80mm in diameter and 40mm tall, with a 7.2mm spindle hole, weighing 460g according to the spec sheet. The surface is finished with oxidation treatment and laser engraving, and the ergonomic shape is designed for easy, accident-free handling.

On the record, the weight does one job: hold the vinyl flat against the platter. Douk Audio says this maintains stability and improves acoustic quality, describing the results in listening terms: piano notes become crystal-clear, the mid-range feels vibrant and alive, and vocals soar more realistically. The claimed mechanisms are reducing resonance and vibration, stabilizing rotational speed, and lowering the noise floor, which the company sums up as purer signal retrieval, better stereo imaging and focus, and more realistic sound reproduction.

Included accessories are thoughtful for the price: a soft base pad protects LP covers and labels from the metal body, and a protective carry case keeps the weight safe when not in use. The 7.2mm spindle hole fits most existing turntables, and the perfectly balanced aluminum construction is meant to stabilize the sound image and improve output when dubbing quality CDs from LPs.

One note for careful shoppers: the listing title mentions a 420g weight while the description's spec sheet states 460g, so it is worth confirming with the seller which measurement applies to the unit you receive. Also check clearance, since 40mm of height may exceed the space under a closed dust cover on some decks.

What we liked

  • 460g of non-magnetic aluminum presses records flat against the platter to stabilize rotation
  • Douk Audio says it reduces resonance and vibration, lowers the noise floor and improves stereo imaging and focus
  • Oxidation treatment plus laser engraving gives a precise, durable finish in black or red
  • Ergonomic shape allows easy, accident-free handling, and the soft base pad protects the record label and cover
  • Ships with a protective carry case, and the 7.2mm spindle hole fits most existing turntables

Worth noting

  • The listing title mentions 420g while the spec sheet says 460g, so confirm the exact model weight before ordering
  • At 40mm tall it may not fit beneath a low closed dust cover
  • It adds 460g of mass to the platter, which lightweight or suspension turntables may not be built to carry
