I've got both, just switched from Recoil Stabilizers on my desktop to Isoacoustic on some stands I built for my JBL LSR4328s. To me, the Iso stands sounded better on my desktop, and even better on the stands (MDF & PVC, sand filled etc). The weird thing is that the Recoil Stabilizers definitely damped more vibration, by a mile in my case, but sounded worse. I don't know if that's b/c the back half of the recoil stabilizer was hanging off the top of the desk, probably so. At any rate if you have stands already the Iso stands are pretty cool and worth checking out. Everything seems clearer and more separated, bass more clear, etc.
