Our Technology
Music is delivered through vibration. External vibrations mask and distort music; our mission is to remove parasitic vibration and reveal the pure musical vibrations the artists intended. Vibration control is a multi-faceted engineering challenge whereby we are committed to improving texture, timing, and spatial location.
We Only Make Rigorously Tested Products
Every Stack Audio product earns its place through prototyping, measurement and long listening tests. If a design doesn’t deliver a clear, repeatable improvement, it doesn’t go into production, a standard independent reviewers have verified with measurements of their own.
Removing the Vibrations, Revealing the Music
We focus on three areas of expertise, using fast dissipation technologies, a more effective approach than slow mass absorption. Manufacturing precision, rigidity, and shape are key to peak performance.
AUVA
AUVA is our patent pending technology that integrates a phenomenon called particle impact damping to absorb a broad range of frequencies.
CSA
Custom Silicone Absorber. The specific molecular properties of the silicone used in CSA play a critical role in its ability to absorb vibrations effectively.
TAPA
TAPA builds on the same particle damping principles as AUVA, but has been adapted specifically for the complexities of playing vinyl on a hifi.
FCI
Inside each SmoothLAN product is multiple circuit sections, each performing a specific role, from power regulation to signal processing.
AUVA
AUVA is a patent pending technology that utilises a phenomenon called particle impact dampening to effectively reduce audio vibrations and enhance sound quality. The technology absorbs vibration energy and converts it into heat, through friction and collisions between particles.
Found in the following products:
Our Patent-Pending Innovation
The AUVA isolators use multi-chambered, tuned vibration absorbers constructed from materials that absorb the broadest range of frequencies that are transmitted and dissipated efficiently. The carefully designed precision-machined body vibrates passing the energy through to the particles which are excited and collide absorbing the vibrations.

CSA
The specific molecular properties of the silicone used in CSA play a critical role in its ability to absorb vibrations effectively. We worked closely with a silicone specialist to ensure that each CSA is fine-tuned to meet precise performance specifications.
Found in the following products:
Specially-selected Silicone
The CSA forms an air pocket that acts as a spring while the air holes provide extra compliance. The shape has been specifically modelled to absorb particular vibration ranges which are harmful to the purity of the Audio Signal. We craft our products with Silicone due to its unique property traits.

TAPA
TAPA builds on the same particle damping principles as AUVA, but has been adapted specifically for the complex, low-level vibrations of vinyl playback using a lightweight, tensioned membrane system.
Found in the following products:
Designed Specifically for Vinyl
TAPA suspends a layer of free-moving particles on a lightweight, tensioned silicone membrane. The tiny movements of vinyl playback (stylus energy, acoustic feedback and ambient noise) set the particles in motion, dissipating vibration at the record itself. Unlike heavy clamps and weights, it preserves the music’s natural dynamics without tonal shifts.

FCI
FCI, Fully Compartmentalised Isolation, shields each SmoothLAN circuit in its own precision-machined pocket, so every section performs at its best, free from its neighbours’ noise.
Found in the following products:
Featuring Fully Compartmentalised Isolation
At the core of the Regenerator’s performance is Stack Audio’s FCI (Fully Compartmentalised Isolation)
Each circuit is shielded in its own precision-machined pocket, surrounded by exposed gold, providing the shortest, lowest impedance path to ground. This ensures each circuit can perform at its best, free from surrounding noise interference.
