Anybody have both Herbie's Cone/Spike Pucks and isoacoustics gaia's

Whether you try the Gaia footers or Herbie’s products (Giant Fat Gliders or Giant Threaded Stud Gliders), I would try them directly on the carpet. The Herbie’s stuff comes with a 60-day trial period. Check our Herbie’s website. 

Like the previous poster Ray, my speakers are supported on springs and IMO they work and sound very good, inexpensive too.

Townshend formerly used air-platforms as a method of isolating equipment and speakers from vibrations (i.e., Townshend  Seismic Sink) and have since switched to using pre-compressed, damped, springs in the form of the Townshend Seismic Isolation Pods, which serve the basis of their current line-up of isolation products for electronics, stands, and speakers, such as the 

• Townshend Seismic Vibration Isolation Platform for electrical equipment, 
• Seismic Isolation Podium for speakers, and 
• Seismic Vibration Isolation Stand

Some of us are using free-standing, damped springs, which are not as elegant a solution as the Townshend Pods but when properly sized and implemented may offer the same level of performance, or close to it, for much less money.

Sound Anchor stands can make it easier to use some of these footers, like the Townshend pod solution outlined by @bdp24. Unfortunately, the 8 I would need for my main speakers would still cost me around $1K. The springs I am currently using under my main speakers cost me about $30 per speaker.
