How much do you think the platter weighs?
well thinking out loud this morning. It’s a "look Mom no hands" free floating design, so permanent magnets must be embedded in the platter in some pattern. The plinth portion is using electro magnetic forces. So one idea is; I am visualizing a repulsive force on the inner part of the platter, and some kind of metal ring embedded in the platter closer to the rim. This metal ring provides attraction to the plinth’s forces keeping the platter aligned. We don’t know what kind or amount of electro magnetic force is involved, but the platter floats very high. With cartridge shielding considerations, this makes me think the platter is therefore not very heavy. Without knowing what the actual materials are that the platter is made of, I am guessing, so let’s say a few pounds.
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.
I learned from personal experience, never to trust videos and pictures. Especially if you are buying a used boat 8^0.
Damn, when you go to see them, they always look worse than the pictures and videos.
Tolerances is IMO what the audiophile should focus on, when buying a packaged turntable setup (table, tonearm, cartridge). Tolerances are what separate the men from the boys. What should separate a 4 figure turntable package from a 5 figure one.
So a friend buys a 4 figure turntable package. Table, tonearm and cartridge. He levels the plinth feet to the point where the platter is level in the general area where the tonearm will travel. He then checks the level of the tonearm armboard which is fixed to the plinth. It is not on the same plane as his platter. His tonearm (the one that came with the package) does not have a self leveling system. What’s he going to do ? What happens when he goes to check the other half of the platter ? Is it on the same plane as the side the tonearm rides on ?
I think the person buying this Mag Lev turntable setup is not even thinking of tolerances. He or she is thinking this is so cool, I have to have one. In the end it is always the cartridge and some records that are the victims in a bad setup /design. The website says they have some folks using the product and providing input. Hopefully someone from the project team will have a look at the cartridge after XXX hours, to see what is really going on. To find out the truth. And this reminds me. if someone is having a cartridge re-tipped don’t forget to ask your re-tipper to check the wear pattern. To find out the truth.
