New Mag-Lev Turntable

You know, what doesn't make a lot of sense to me at all with Audiophilia, is that we have some "well heeled" Audiophiles searching for that sound; spending thousands on gear. And as we are in the analog forum here, this means - multiple turntables, tonearms, even more cartridges. Yet, they do not take a small portion of that budget, and buy a good reel to reel with one days worth of 15 IPS master tape dubs to use as a reference point . Seems like an obvious way to start at Ground Zero with a good Analog Audio Reference .... and go from there. Let it guide your journey. What better way?  Just makes sense to me.

+1.

I think a set of really good mics are a good investment too (I bought a set of Neumann U67s in 1984). The ability to use that tape machine with good mics really helps in establishing a good reference. These days I also run a small recording studio. We have Studer, Ampex, Sony, Otari and Tascam tape machines, as well as a Scully lathe with a Westerex 3d cutter head.

I would think that anything that separates the platter and tone arm, allowing either to be suspended independently from the other would be a problem.

There is this subtle but important difference between "I think" and "I would think" :^)

If a person says "I think"., it is a straightforward statement about their thoughts on the matter. However "I would think" means that the person would probably argue for whatever is being discussed, if they were asked the question or put to the test.

So for this reason just one question really - is your opinion based on theory, or personal experience ?

if it is the later - personal experience, always looking to learn.

as we know...
Air bearing tonearm spindles are, "suspended", "levitated", and ride on a film of air. Some are partnered with direct coupled turntable platters. while with others, their platters are also levitated. This has been happening since well the 80’s anyway, and is still happening today.

How do you think this Mag lev table platter stays aligned ?

I think it has to do with same pole repulsion for the main part of the platter and around the edges there is a circular opposite pole pattern. . What do I know. You are the NASA guy right ? What do you think ?

I don't know. How much do you think the platter weighs?

I think that air bearing tone arms are considered rigid, and they fall within the same tolerances as standard bearings. I'm not so sure that this magnetic platter design does. From the video you can clearly see a large variance where the platter deviates from flat. Now, whether that is from loose tolerances when manufacturing the platter or suspension effect is unknown.
 
Also, it would be interesting to knock the side of the plinth and see what happens to the platter, as well as, what happens to the whole table while playing an album.
