HRS Isolation base

Anybody have any experience with this product? Your opinions would be appreciated.
They are fantastic! These are products designed by an aerospace engineer who worked with vibration control issues. Serious engineering and quality into these products. Notice the Brinkmann turntable review in Stereophile. Brinkmann chose HRS to make their stand...with good reason.
I agree 100%, they are outstanding on front end gear!
HRS is the very best there is. Very few know this truth and that's to bad as many are missing out on how good their components can sound using HRS products.
