Solid Tech - A new brand for racks and stands

The "High Performance" racks are solid-to-solid connections but claim anti-vibration... just marketing ploys

The "Extreme Performance" racks actually control vibrations, but have big problems holding weight due to a spring suspension design. Over time, the spring will sprung :)

They do not address some of the bigger concerns with expansion, heat, EMI, ESD and magnetics. The spring is metal and will transfer static... not sure if a reference piece should not account for this.

They get a ten for asthetics and creative writing though...

I am biased, since Audiav is just plain better on a variety options, since they address more than just vibration and inertness. I do like some of the shelves, however, from some other competitor's but you did not mention them in your short list of those three.

BUT, if I had to buy one of the three over, rather than an Audiav piece of course, I would get:
Finite E's Grand Master for looks... Grand Prix Reference if I was inviting teenagers over to look at the carbon fiber, and Silent Running Audio if you removed half of my brain (the logic portion of course :)

I am a "got-so-many-features-you-don’t-need-hype" kind of guy, so I think that offering a platform that can address ALL the big concerns at once is the way to go. I do not like manufacturers that create silly marketing spins about sand and filament boxes when they don’t really do anything but add mass.

My perfect ideal is one that holds massive weight and blocks:
-Heat
-Vibration
-Magnetic Fields
-Induction
-Static
Fully topped in thick Granite...
and happens to have a gemstone in the emblem :)

If I understand the question from Theaudiotweak... no rack platform can affect the internal self-induced vibrations at the source, to limit effect on the source. They can only affect the out-bound and in-bound from the point of contact. You would need to tear apart and modify a poorly made offending source component or chassis... pertaining to the source (of vibration). Airborne vibration cannot be controlled in an open architecture design, as the sides and front/back are open. An enclosed baffle would need to be placed between the air movement and the component to minimize... but that goes beyond a common audio rack and turns more into a chamber. But a shelf could help minimize transference to and from the frame and to and from the platforms.
