For audio component decoupling- CD players, preamps, amps, DACs, etc with extra-tall factory feet. Four Big Tall Tenderfoot isolation feet plus optional SuperSonic Stabilizers for full-chassis vibration damping.

Suitable for components with factory feet up to 1" tall.


Tenderfoot isolation feet are designed to be used in direct contact with the component's chassis to both isolate from external vibrations and damp chassis micro-vibrations. Delivers a full-bodied and quick, highly articulate result with amazing linear extension, without the coloration typically associated with compliant footers.

Individually molded with a proprietary platinum-cure silicone blend formulated in-house in consultation with Wacker Chemie AG of Germany for maximum micro-vibration absorption. Recommended for audio and video components weighing from 2 to 220 pounds (100kg).

Particularly well-suited for CD/DVD and SACD players, DACs, Blu-ray Players, preamps, power supplies and conditioners, turntables, and power amplifiers.  Works equally well with solid-state and tube components. Does not "ooze," mar, or discolor surfaces. A thin decoupling grungebuster Dot is adhered to the base of each Tenderfoot (Extra-Firm version has black grungebuster Dot).

Two versions available:

TenderSoft: for components weighing 40 pounds or less (18kg)

Extra-Firm: for components of virtually any weight up to 220 pounds (100kg).

Dimensions: 1.18" x 1.18" x 1.02" tall. (30mm x 30mm x 25.9mm)

Default recommendation: four Tenderfoot isolation feet per component.

Though scarcely ever really needed, pressure-sensitive adhesive is an available option.


SuperSonic Stabilizer is a fluorocarbon and metallic composite for use on top of components to increase overall efficiency of compliant isolation feet like Herbie's Tenderfeet and Iso-Cups. Not a mass-loading weight, components are stabilized similarly to resting your palm gently on top of a component, reducing upper-chassis vibration considerably. A thin decoupling layer of black elastomer on the bottom protects component surfaces and prevents the Stabilizer from sliding.

We recommend two Stabilizers for most audio and video components. They can be stacked together or spaced separately on the component. For smaller components like some DACs, power supplies, and small CD players, one Stabilizer will do. (Additional weight can be placed on your Stabilizer if you like (e.g., lead fishing weights, sand bag, decorative objects); the Stabilizer will decouple your component from the added weight while still transferring more virtual mass to the component.)

SuperSonic Stabilizer is also effective on top of amplifier transformers, on rack shelves, as a base under component feet, and other vibration control applications.

Dimensions (each): 2-7/8" (73mm) diameter, 1/2" (12.7mm) tall. Weight: 167.4 grams (5.9 oz.)
