So, “Audio Science Review” really doesn’t like this video

Thanks for this. I enjoyed the video, and agree completely with the basic takeaway.

I don't think that there is any question that well-deigned dampening devices are superior to spikes and cone designs, and for the reason that Mark describes: the latter are actually coupling devices.

While I believe that Townshend are likely the best dampening devices on the market, I use IsoAcoustics GAIAs, as like Mark in the video, I have stand mounted speakers. Interesting, Karl-Heinz Fink, the brilliant, in my view, designer of my Fink Team KIM speakers, employed an uncommon approach to the interface between the stand and speaker: they are integral. In other words, the stands, which are neither very heavy, nor filled with lead or sand, are firmly attached to the speakers themselves at the factory. This design allows users to employ any types of footers that they like to the stands, and mitigate vibration issues in that manner.

So, I use the GAIAs as feet, and to excellent effect. The difference between the sound with spikes, and the GAIAs, is quite clear. Less smearing, better imaging, and tighter bass are all noteworthy.

As for the Audio Science crew, it's hard to tell what took that discussion off the rails. But given what I believe to be well understood about the distinctions between coupling and damping devices, which is the essence of the video, I don't know what serious objections might have been made relating to Mark's conclusions.

Well I don’t agonize over things like this the way a lot of audiophiles do.  When GAIAs first were introduced to rave reviews, I tried them and really liked them.  The first place I installed them was under my Sony SS-AR2 floor standers on a slate covered, steel reinforced concrete slab floor in my home in South Florida.  They amazed me.  Recently I installed another set of GAIA IIIs under a pair of B&W 802 D Diamonds in our summer home in New Hampshire.  This is a hardwood floor over a basement, somewhat spongey and again the improvement was astounding.  I have also used GAIAs, under three turntables with excellent results.  So it is no surprise to me to learn that others have similar experience.

Ten Misconceptions about Loudspeaker Spikes

I find what I call alligators along side the road .if you follow big trucks to close they throw things at you.its great for the environment because I clean the spent tire parts that's part of a big government grant I got it's working great.the side deal is my friend has this business chopping the alligators up ie tires and they use it for playground material. I figure what's good for the kids is good insulation for the speakers heck tires make your car ride better. After all most of these isolators are made of rubber.then I go to harbor freight and buy these expensive isolators called carpet dollies.i have my 700 lb magico q7 on them and roll them around for exercise.reminds me of Jane fonda. I think the drop the mic moment was a bit of humor and he stated he didn't know how to interput the data and that hurt some feelings. Having done alot of research there is scientific data variance. Enjoy the experience stay healthy don't eat red dye and keep happy.
