Townshend platforms vs SRA platforms

BTW-IsoAcoustics seems to be similar to Townshend. That is using rubber.

SRA was clearly sure that any pods or feet defeat the function of their platforms. They said that the platforms are designed to work with the stock feet. Although I do use Stillpoints with my TT platform. And Ralph uses them with his preamp too.
My mind is open as to which is better-SRA or Townshend.
All I am sure of is that the SRA platform under my TT is nothing short of spectacular. It is like the SRA allows the TT to fully function as designed. And, to my knowledge, Townshend is not used in critical scientific, military and medical as is SRA. So much so that they call their upper line Ohio Class and Virginia Class and their company the submarine term “Silent Running” Audio.

Hi Chuck
I was surely thinking of you when I posted.
SRA is oriented toward end users whom are at the point of destination when ordering. In a way, this amplifies things when applied to beloved, forever components.
And there is quite a difference with the Townshend being so effective under speakers. I think this is a very different application from TTs and other components. I don’t see SRAs used much for speakers.
Although my “solid” Stillpoints under my speakers are also super effective.

So, am I to understand that the Townshend platforms use some kind of spring? Think this refers to my op. Or are the Townshends actually more on the solid side? BTW-the SRA Ohio Class platforms considerably more than the Tp.
Then we have the perennial issue of price vs quality.
Another thread?
