What a debacle this one is. Youtube alone should kill this. Unless the arm is also levitated the concept is flawed. Appears to provide it's own warp at this point.

What happens if you put a finger under the platter? Will it all break down then? :D
Sure looks wobbly...

Why are we concerned about a wobbly platter, asmuth alignment, VTA? What... none of that really matters after all this time? ...and hey, turns out all those warped records I have thrown away were perfectly fine after all.

Cool concept, but definitely NOT ready for production.

Ed Villchur would be spinning in his grave. This is so against the main principle he introduced with his XA turntable.

This turntable is just as ridiculous as the day they first announced it. $3000 for a conversation piece / status symbol? Doesn't appeal to me, but I'm sure they'll sell a lot of them just the same.

There IS a way to use magnets to improve the function and performance of a turntable. Technics did that with their direct drive system 40+ years ago. Magnets in the base of the turntable repel magnets in the platter. It's a beautiful design, in both form AND function.

(Aside: is there an unwritten law that requires YouTube personalities to be as annoying as possible?)

I live a couple of km away from where they produce them and while I wish they nailed it, its far from that. By trying to remove the platter vibrations, they created a platter which is an earthquake simulator, and that is what extreme vibrations show as - massive up and down movement. So pointless, maybe the next generations will be better but from what I have seen from the videos it was pointless for me to visit their factory for a sound test.

And I know it is pointless to criticize, but magnetic interference, no specs in their site, a non d-balanced platter, not to mention they need to make another spec for the platter wobble, thats a first.

And also the price, in the kickstarter days the price was around 1k, now with a slightly better tonearm 3k, seriously?

Maybe if they aimed at the high-end market with a stupidly massive platter things would went differently.

Kind of makes me sad when I see today mass market, this mentality extends way beyond this turntable. People will eat everything the companies throw at them, without even applying some basic thought.

Perhaps they can tie the platter and arm together in an integrated assembly, so if they move, they move as one, and levitate that. Much more expense there. Also specs should be better, at this level.

But if they did that, then you mess the tonearm ability to track. The tonearm needs to be as stable as possible to track the grooves. A tonearm which would move with the platter would cause all sorts of problems.

Not necessarily : look at Thorens suspended chassis, for instance.

Yes, but did you ever see a Thorens sub chassis moving around by half a cm? It works in that case because the movement is minimal.

It worked over 50 years ago with the AR turntable. The arm and platter moving as one---they were suspended on a subassembly---eliminated a lot of problems.

:wink: If I had the time and the money to waste, I'd get one of these, just to show it off, to impress and astonish people. No, I would not use it to listen to music. Probably equip it with an AT95E.
