I have GAIA Series under my speakers;
"The GAIA speaker isolation feet consist of acoustic isolators contained within an elegant machined dark chrome metal housing. Incorporating IsoAcoustics patented design principles, the GAIA’s provides a high degree of isolation while resisting lateral movement and oscillations to maintain alignment with the listening position. Internal reflections from the hard-supporting surface are attenuated resulting in greater sound clarity and openness. The GAIA’s will reveal clarity and openness from your speakers like you’ve never heard."
Also, I have OREA Series under my components;
"Experience the Orea Series audio component isolation feet, designed to eliminate parasitic vibrations and provide greater sound clarity and focus. Ideal for electronic components such as Amplifiers, DACs, CD Players, Speakers, and Turntables, the OREA isolation feet are made of machined stainless steel and feature a low-profile design to minimize any increase in height."
Highly recommended.
