Whilst we can agree that HifiStay's Vega are just accessories and no more, they happen to be demonstrably effective accessories. Being of the purely mechanical sort, they also elude basic voodoo reactions even if their employ under speakers is a bit of a mind bender. I confess to being a sufficiently practiced cynic that my very happy conclusion came as a bit of a personal surprise. I'd much prefer to keep things simple. I'd much prefer to say no to assorted tweaks and accessories, not endorse their use to add to the list of things to worry about. But when something works as plainly and well as these Vega gyrotension footers do, should one worry over that precious membership in the sane-guy club? No. And what's really so bad about being outed as a freshly minted Vegatarian? Just form a new club. Tell 'em the Vs have landed... - 6 Moons Review

Floating type vibration isolator by radial symmetry silicone ring structure.
-Adjustable tension setting by the number of rings.
-Double vibration isolation design by silicone rings and 3-point support ceramic balls
-Radial symmetry ring design absorbs, diffuses and dissipates all kinds of vibrations more effectively.
-Precisely machined duralumin body and hard anodized top plate.
-The number of silicone ring layers: 
 .Medium - 4 layers (48 rings)
 .Large - 6 layers (72 rings)
-Height adjustment range: 20mm(0.79 inch).
-Dimension(Diameter*Height): 
 .Medium - 60*42 mm(2.35*1.65 inch), 
 .Large - 79*47 mm(3.11*1.85 inch)

[Recommended load]
-Medium: max 10Kg/each (48Kg (88 lbs) for 4-point support)
-Large: max 15Kg/each (60Kg (132 lbs) for 4-point support)

[Ring tension / each]
Recommended for audio equipment: 200~225g (0.44~0.5 lb)

[Recommended tension adjustment by applied loads, max]
(Assuming 4-point supports and large 6-layer rings.)
Under 11Kg: 1 layer
12 - 22Kg: 2 layers
23 - 32Kg: 3 layers
33 - 43Kg: 4 layers
44 - 54Kg: 5 layers
55 - 65Kg: 6 layers
*You can adjust the tension by the number of rings.

Optimum load table
 

Vibration in audio equipment is a serious problem that can't be ignored. If you remove it in any way you can improve 
the sound more than you can imagine. It makes very firm, disctinct and deep bass level. Mid-range is very smooth 
and detailed and no irritable and aggressiveness in high frequecy range. Clear, firm and wide sound stage mean that 
it's getting close to the natural sound. 

The Gyrotension Isolator is the ultimate resonance/vibration control device that employs the most precise and absolute 
resonance/vibration absorbing, dissipating and eliminating function. 
The Gyrotension Isolator is the most effective device for the vibration from the outside. One of them is "Ground-borne 
vibration" and universally accepted as one of the major reason for the variability in the performance of audio equipment. 
However tiny a vibration may seem to us, it will affect huge impact to the hi-fi audio signal processing systems.


You can set the optimum load by hooking the calculated number of rings. Recommended: 250g (0.55 lb)/each ring
