Stack Audio Auva Platform isolation base
Stack Audio introduces the Auva Platform, an all-new precision-engineered vibration isolation platform designed for turntables, amplifiers, DACs, streamers, and CD players.
Unwanted vibration reaches sensitive components and interferes with signal retrieval, no matter how well the rest of your system is performing. The Auva Platform builds on the same Auva particle damping and CSA (Custom Silicone Absorber) isolation technologies used in our Auva EQ feet, combining them into a dedicated full-size platform.
A different approach to isolation platforms
While many isolation platforms rely primarily on mass loading or constrained-layer damping, the Auva Platform (£1,440 (£1,200 ex VAT)) introduces a hybrid design engineered to actively absorb and dissipate vibrational energy. At its core is a finely tuned internal structure designed to manage and dissipate vibration efficiently.
The Auva Platform features 35 individually tuned Auva damping cells, housed within a reinforced honeycomb wooden structure positioned between two precision-machined anodised aluminium metal plates.
This structure is designed to channel vibrational energy into the damping cells, where carefully selected particles dissipate energy through rapid micro-collisions. Each cell is tuned to target specific frequency ranges, enabling effective control of resonance across a broad spectrum of vibration.
CSA isolation feet
Supporting the core are Stack Audio’s CSA (Custom Silicone Absorber) isolation feet, each operating as a precision air-spring system housed within a machined enclosure featuring fine-pitch micro-adjustment.
The CSA design adds compliance and is tuned to respond to a wide range of real-world listening environment frequencies, promoting fast energy decay and preventing the build-up of resonance.
By combining controlled dissipation within the core and compliant isolation at the support points, the Auva Platform provides a stable, low-resonance foundation for connected audio equipment.
Specifications
Dimensions: 450 mm x 380 mm
Height: 34 mm (excluding micro-adjustment)
Weight: 9 kg
4 sets of 4 CSA Isolation Feet for different equipment loads
4 direct coupling adapters
Maximum load capacity: 100 kg (220 lbs)
Each Auva Platform is supplied with four sets of interchangeable CSA isolation feet, matched to equipment weight requirements.
Equipment can be used with stock feet resting directly on the Platform’s surface or coupled via the supplied precision-machined adapters for a rigid, direct connection to the unit’s chassis. Threaded holes allow for 3 or 4 adapters to be used in different arrangements.
