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.

@mglik: IsoAcoustics uses rubber as the isolation material in all their footers, Townshend does NOT. The rubber sleeve into which the Townshend spring is installed is not employed in an isolation function, but as a very clever means of creating a damping characteristic in the Seismic Pod. There is nothing else like in on the market.

Yeah, I was kidding about Pods under them, that's why the ;) which is all my crappy work PC can do. Every manufacturer I've ever talked to says you cannot improve on their factory feet. Or any other aspect of their product, btw- and that's no joke! lol!   

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?
