That is nice for the platter, I can dig it. But what about the tonearm? In would porter the tonearm and platter move in sync rather than have the tonearm independent of the platter.
Even though I haven't got a clue what you meant to say in that last sentence Flint I think I see where you are going with this. Maybe. Potentially. Ah hell! WTF were you trying to say!???
In any case let's noodle whether the platter and arm should, or should not, be "coupled" (mechanically - or in this case electromagnetically).
Hmmm...
I find myself thinking about the platter alone for a moment and wondering just how effectively it is in fact "isolated" and if it is, what kind of effective spring rate / damping exists? From the video, when the platter is tapped there seems to be a very long period of time (relatively speaking) for it to return to "steady state" which indicates very little damping effect.
I'm also thinking that there are four possible ways of looking at this:
1. "Conventional" platter and tonearm;
2. Mag platter and conventional tonearm (which this product has);
3. Mag platter and tonearm (assuming that's somehow possible for the tonearm - how do you get the signal through the mag barrier? Digitize and transmit somehow? How would you power that process?); and
4. Conventional platter and mag tonearm (ditto).
I'm stuck on imagining a way that the tonearm could be truly mag-isolated - either alone or in concert with the platter; short of simply levitating the whole thing (ie. eliminate the feet from a conventional turntable.) In that case you're just talking about a fancy way of having better feet - which you can already do in many other ways using tried and true vibration reducing techniques.
So that seems to leave us with 1 and 2. And there's any number of 2s (ie. conventional turntables) out there, so that only leaves option 1.
So (again for the discussion that you started and I'm trying to continue) it all comes down to the actual isolating characteristics of the design of this product. It might be "isolated" in appearance; but that's likely all it is. Unless we had a sample to play with and could try it out in some real-world situations. (For starters I'd sit it on top of a sub and see what happens!)
