I recommend and use Herbie's "Fat Dots" to couple my Harbeth's to Sound Anchor stands. However, I strongly preferred coupling Sound Anchor stands with supplied steel spikes to the concrete slab floor over carpet vs. using Herbie's Gliders, as there was a noticeable loss in transparency and imaging with the gliders. YMMV.
What Are Your Experiences with Decoupling Products and Your Recommendations?
I've heard IsoAcoustics to Stillpoints are the way to go. But I've also heard HerbieAudio is a great (inexpensive) alternative and not over-engineered. What has been your experience and what in your opinion is the cost/benefit threshold?
