I own Bliss Hifi, a high-end audio boutique, and these Stack Audio Auva 70 isolation footers are being listed as a consignment sale on behalf of my client for whom I am selling his entire system. He is the sole owner and purchased these new. They are in very good cosmetic condition and perfect working order.

The set includes six Auva 70 footers with fitted with M8-1.25 threaded adapters, standard spikes and felt pads. This set of six is ideal for a pair of three-footed loudspeakers or stands, and additional footers can be ordered directly from Stack Audio if your setup requires more. I am happy to facilitate that process for you.

The Stack Audio Auva 70 is one of those rare accessories that punches well above its weight class. Designed and manufactured in the UK from solid billets of machined aluminum, each footer contains three internal cells packed with a proprietary blend of particles including tungsten. When vibrations enter the footer, those particles collide and convert the energy into heat, effectively eliminating resonance before it reaches the floor or feeds back into your loudspeaker. The result is immediately audible: tighter, more defined bass, cleaner vocal reproduction, and a more focused and dimensional soundstage. Unlike compliant isolation products that allow movement and compromise speaker stability, the Auva 70 holds your loudspeakers rigidly in place while simultaneously absorbing vibration, preserving the spatial detail and timing that matter most to the listening experience.

Check my stellar feedback on popular marketplaces and buy with confidence. This listing includes free insured shipping across the CONUS. As this is a passthrough sale that I am brokering on behalf of my client, I can only accept payments via PayPal F&F, Venmo Gift, or personal check, but this also gives you the opportunity to attain this at my lowest possible price.

Happy to answer any questions. Thanks for your consideration.

More about the unit: The Stack Audio Auva 70 is a speaker isolation footer that uses the company’s patent-pending AUVA (AUdio Vibration Absorber) technology to hold loudspeakers rigidly while dissipating cabinet vibrations before they reach the floor. Each Auva 70 measures 70mm (2.75″) in diameter and 30mm (1.18″) in height, weighs approximately 370g, and supports up to 70kg individually or 275kg per set of four. Three internal cells contain a carefully selected blend of particles, including tungsten, that collide under excitation and convert vibrational energy into heat, effectively eliminating resonance rather than merely redirecting it. The Auva 70 additionally includes a central particle-filled chamber for extra absorption capability beyond the base Auva 50 model. Each footer is machined from a solid billet of aluminum and finished in black anodize. The footers attach via threaded bolts into the existing mounting holes on the underside of loudspeakers or stands, with a wide range of thread adapter sizes available to accommodate virtually any speaker on the market. The included accessories provide both carpet spikes (available in 15mm or 25mm lengths) and protective felt pads for use on solid floors. Compatible with both stand-mount and floor-standing loudspeakers, the Auva 70 has earned widespread critical praise for delivering improvements in bass definition, midrange clarity, soundstage focus, and overall musical timing.
