Based on user reviews and community discussions, the Stack Audio AUVA EQ Isolation Footers are widely praised for delivering significant sonic improvements at a competitive price point.
## Sound Quality
Users consistently report substantial improvements in clarity and soundstage after installation. Reviewers note increased openness and expanded soundstage depth, with one user describing the sound as having "warm spaciousness" that moves slightly away from the listening position. The isolation feet produce tighter, snappier bass with improved control and texture, while the midrange becomes more forward and present with better instrumental separation.
One user found the AUVA EQs allow "wide bandwidth playing of music" while providing slight smoothing without dulling the sound. The improvements reportedly extend across musical genres, from electronic to orchestral content.
## Build Quality and Design
The AUVA isolators feature aluminum housing with internal dampening cells engineered to hold speakers rigidly while absorbing vibrations. Users appreciate the robust construction, with one reviewer noting that upgrading from compliant footers (rubber, foam, springs) to the rigid aluminum design delivered more clarity and control than previous attempts with similar products.
## Value and Reputation
Users consistently emphasize exceptional value for money. Multiple reviewers compare the AUVA EQs favorably to competitor products like Stillpoints and Townshend isolators, with one user stating that at 3x the price, alternatives "simply don't make sense". The product line includes entry-level AUVA 50, mid-tier 70, and premium AUVA 100 models with varying numbers of dampening cells.
## Installation and Documentation
Installation is straightforward, with detailed instructions covering both setup and general speaker positioning advice. The isolators attach via supplied threaded bolts to existing mounting holes on audio components.
## Overall Assessment
Users describe the AUVA EQ isolators as a high-impact upgrade requiring minimal effort—most reviews emphasize the dramatic sonic improvement achieved by simply swapping footers without modifying cables, power cords, or settings. The products come with a money-back guarantee, allowing risk-free evaluation.
