2 packs of IsoAcoustics GAIA isolation feet for speakers up to 55 kgi.e. 8 individual feet as per the photos https://isoacoustics.com/home-audio-isolation-products/gaia-series/I assume they need little introduction. Would have been used for 12 months at most so are in excellent condition. Bought ...
Compared with buying a cheaper generic isolation foot, A$550 is a fair price for a used set of IsoAcoustics GAIA II: it matches the median of three recent comparable listings, well above the A$401 25th percentile but below the A$599 75th percentile. It is not a bargain, but neither is it ambitious—assuming the listing is for a complete set of four.
The GAIA II is a worthwhile upgrade for compatible floorstanders or subwoofers up to 54 kg per set, particularly on suspended or vibration-prone floors. Its threaded connection, compliant isolators and stable footprint can sharpen bass definition and reduce energy transferred into the room. Check that all four feet, locking hardware, installation wrench and M6, M8 and 1/4"-20 adaptors are present; a pair of speakers needs two sets. With unknown condition, confirm the isolators are intact and the threads undamaged before paying the full A$550.

IsoAcoustics, a Canadian company founded in 2012 and headquartered in Markham, Ontario, traces its roots to the expertise of Dave Morrison, who spent nearly two decades designing and building radio and television studios, including Toronto's massive multi-media center. This studio heritage directly inspired the brand's patented isolation technology, which addresses vibration control at its core, evolving from professional environments into accessible audio solutions.
The brand specializes exclusively in acoustic isolation products, such as speaker stands, monitor bases, and isolators like the GAIA series, ISO-PUCK, and OREA. These target studio monitors, floorstanding speakers, turntables, subwoofers, guitar cabinets, and DJ gear, serving both pro audio/project studios and home hi-fi setups without venturing into amplifiers, DACs, headphones, or cables.
IsoAcoustics holds a niche boutique position in the mid-to-high-end market, renowned as the go-to for vibration reduction that unlocks superior clarity, focus, and openness in sound reproduction. With rapid growth to distribution in over 70 countries and presence in top recording studios worldwide, its elegant, award-winning designs appeal to discerning hi-fi enthusiasts and professionals seeking transformative upgrades.
