What Are Your Experiences with Decoupling Products and Your Recommendations?

Using Magico Qpods and Symposium roller blocks which in my system was much better than any Stillpoint footers.Stillpoints tend to favor the highs over the rest of the frequency spectrum.IsoAcoustics are better than Stillpoints in the systems i have heard.

OP
If by "decoupling products" you include speakers then yes, hell yes!
The cool part about decoupling your speakers is that not only do you relieve the rest of the house from having to experience the deep bass but it also helps to keep speaker vibration from affecting the system components.  And yes, Herbie's gliders work extremely well in decoupling cone/spike coupled speakers and subwoofers from the room.  I use Herbie's Tenderfeet under most of my components as part of the system "tuning" process.

Yep, Herbie’s slider pucks for me... easy and inexpensive. They just work.
