From what I understand there is no such thing as "decoupling". Decoupling suggests we are breaking the rules of gravity, which I find a little disingenuous. "Decoupling" was probably derived by someone in the marketing department, certainly not a scientist.

With all due respect, it sounds as though your understanding is identical to that of Robert, of LVA. Ironically, I consider some of his claims to be disingenuous, as they are based on a straw man argument, namely that those who use the words "decouple", or "isolation", believe that it can be achieved absolutely. I doubt that there is anyone who uses those words within the context of audio components who is suggesting that. In other words, we can all agree that there is no such thing as perfect isolation, nor 100% decoupling.
But approaches such as those used by Townsend and Isoacoustics, etc., are clearly efficacious, even if they don’t completely decouple, or isolate components. There are reasons why some high-class speaker manufacturers (e.g. Marten, Wolf von Langa) include. or recommend them for use with their products.
I can’t personally speak to the relative merits of LVA products, as I haven’t heard them. They may well be excellent, and in (at least) some systems superior to the above mentioned products. But let’s be clear about something: Robert has (marketing) incentive to denigrate competing designs, and the way that he has gone about doing that on various forums reflects very poorly on him. It is one thing to argue that one’s products are superior to those of one’s competitors, and to explain why that is the case. But it is very different to argue disingenuously, as he has, and to play semantic games in an effort to denigrate competitors.
Your arguments relating to speed are interesting, but you fail to mention that coupling works both ways, and so vibrations can and do travel back up from the floor to the speaker. Even if you are correct about the LVA spikes being "faster" than the Townshend spring products, the latter come very close to to decoupling, or isolating the speakers from the floor, meaning that far less vibration will travel back up from the floor.
You have apparently done more research on the topic than I, but I know enough to be confident in my criticisms of Robert. I exposed some of his dubious tactics on this thread, if anyone is interested:
coupling/decoupling
Finally, it is not my intention to derail this thread, and I am glad that you are so happy with the solution that you have chosen.
