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.

Why 3.6/5: Lifted by a stated 80mm diameter, 40mm height, 7.2mm hole and 460g weight, two colors and a $29.99 price below the other weight. Held back by a weight the web address gives as 420g, a pad and case the packing list omits and sound claims with no measurements.

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.

How it compares

The STB-02 is the heavier and cheaper of the group's two record weights. The Nobsound STB-01 Record Weight and Turntable Disc Stabilizer review ($32.99, $3.00 more) lists zinc alloy at 230g, 30mm tall, with a 7mm hole and gold or silver finishes. The STB-02 lists aluminum at 460g, twice the weight, 40mm tall, with a 7.2mm hole and black or red finishes. Both are 80mm across, and both pages make the same unmeasured claims about speed, noise floor and stereo image.

The HiFi Pure Brass Turntable Platter Mat for Vinyl LPs, 2mm review ($69.99, $40.00 more; $79.99 for the Other destination) is the other way to add mass: 1.2kg under the record rather than 460g on top. Choose the STB-02 for the heavier, lower-priced weight if your dust cover clears 40mm; choose the STB-01 if you want the lighter 230g weight or the gold finish.

Shipping, returns and warranty

  • Returns: ask within 30 days of delivery and wait for approval before sending anything; an approved return has to ship within 7 days. Items need all packaging and accessories and no excessive wear, or the store can refuse them or refund part of the price. Refunds go to the original payment method after inspection.
  • Not refunded: original and expedited shipping, duties, taxes and customs charges, unless the law requires it or the store made the error. The return page does not say who pays return postage, and the older refund page excludes mistaken orders and change-of-mind returns from free after-sale service.

Drops, liquid, DIY repairs, lightning, extreme temperatures and misuse are excluded (partial fees may apply), and damage from weak packing on the way back may not be covered.

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

Questions before you buy

Will it fit my turntable's spindle?

The spindle hole is 7.2mm in diameter and, per Douk Audio, fits most existing turntables. The weight is 80mm across and 40mm tall, so check dust cover clearance.

Is the metal magnetic?

No. It is manufactured from high-quality non-magnetic aluminum, which is important for turntable use.

What comes in the box?

The STB-02 record stabilizer with a soft base pad to protect LP covers and labels, plus a protective carry case for storage.

What is the return and warranty policy?

Douk Audio's current policy pages give you 30 days from delivery to request a return, which Douk must approve before you send the item back (within 7 days of approval); original shipping fees and duties aren't refunded. Its warranty covers manufacturing defects for 24 months from purchase, with free repair or replacement.

What we couldn’t verify

  • The review says the listing title mentions 420g; the page title no longer does, though the web address still ends in '420g'. The Parameters give 460g, which is used here.
  • The features say the stabilizer includes a soft base pad and a protective carry case, but the packing list shows only 'STB-02 Record stabilizer x1'; the page does not say which is right.
  • 'Lowers noise floor', 'stabilizing rotational speed' and 'improves stereo image' are page claims with no measurement, and the page gives no turntable weight limit.
  • The page says the 7.2mm spindle hole 'fits most existing turntables' without saying which turntables have a different spindle.
  • 'Gives improved signal when burning quality CDs from LPs' is a page claim with no explanation or measurement.
