Just want to make some comments on SRA. I had SRA craz3 rack before. I believe their rack is a piece of junk. It is so light weight. When I struck one of the pillars, the whole rack rings so much. I also do not buy their claim on specific component design isolation stands. How do they access the data of all audio equipments out there? Do they actually own them and measure them with their so called customize isolation stand? I remember one actually has cut open one of their isolation stands. It is nothing but a piece of plywood with good lacquer paint.

I don't know what your motives are adyc you're entitled to your opoinions, but, pardon me,
you are spreading false and incorrect information.
SRA does not build racks and platforms for "all audio equipments out there." They build to order. SRA's component specific design is based on data about the specific model of component at hand: size, weight, resonance frequencies, transmission curves, propagation responses, etc. Over the years the company has accumulated a huge amount of data about individual audio components and they continue doing so today. The data feeds into in-house computer models that determine the material and type of construction for component solution before it is built. Unlike the vast majority of vibration abatement products, SRA doesn't sell one-size-fits-all. Whether you buy their claim or not does not matter - that's what they do.
If you "actually has cut open" your Craz3 rack you would find its complete titanium endo-skelton embedded within its maple outer shell. A Craz3 is roughly 48"x30"x22". Shelves are 1.25" thick. Solid maple or mahogany and titanium. It's not light weight. Tell us how much it weighs, adyc.
If you actually cut open an SRA VA-Class isolation stand you would find two Raft Isolation systems (look it up) derived from work SRA did for US Navy submarines. That system uses in-house created material that includes hundreds of thousands of pockets of vacuum. That's not "good lacquer paint" it is a proprietary nano-composite skin created in-house and designed to establish a fast coupling between the component and platform.
Almost all the materials used by SRA are created in-house and proprietary. I don't think you know anything about the company and its sister companies in the clinical and military areas that do work with hospitals, stealth aircraft and nuclear submarines. You need high-level government seurity clearance to enter their labs and factories. The owner is a hard core audiophile and the audio related efforts are a hobby that draws from their industrial work.
There is a lot more about SRA products you could learn but somehow I don't think learning is your interest. Maybe you had a bad experience somewhere along the way and are looking to vent, but - I'm being kind here relative to what I'd like to say - no need to throw dirt at a legitimate audio company.
