Has anyone seen this? A really beautiful turntable

I heard of the plinth shooting across the room when accidentally bumped. Looks great!

It pops up in my recommended items some time.  The seller has 3 lifetime sales. I see this thing bouncing all over the place every time you change a record.  Looks cool though.  Like the floating pen on my bosses desk from sharper image.

Good question. Experiment was as follows.

Began with a TT which is famous for the quality of its bearing: Nottingham Analogue, one of the last Mentors, with the Dais bearing (their $10,000 TT). I played this TT for years and years, before:

Decided to build my own DIY air bearing TT. Inspired by the NA design of massive cast iron sub-platter with 1" of graphite sur-platter, I bought a large soft extruded iron billet and had it machined into a 45kg sub-platter. I specified a 1" graphite sur-platter, and an air bearing spindle to hold them. While each of them on its own rings when struck, the assembly is dead as a tomb. Just like the NA.

This assembly is mounted on a porous graphite air thrust bushing from New Way. The plinth is a complex of panzerholz and massive steel. Neither turntable is suspended. The NA plinth was replaced with an aluminum-baltic birch-aluminum sandwich.

Each turntable is fitted with a Trans-Fi Terminator air bearing tonearm. It is easy to exchange wands between them. Cartridge is a Koetsu Rosewood Signature Platinum with diamond cantilever. Phono stage is DIY full complementary push-pull with vacuum and air gap capacitors. Amps are DIY class A. Speakers are Quad ESL’s.

Now the experiment. The motors are disconnected, so that the essential difference between the TT’s is the friction in the bearing. Neither TT has an audible noise component when spinning - that is, audible at a few inches. The only indication of mechanical work being done in the NA is that the platter slows down.

The music produced by the DIY air bearing TT is notably more refined than the NA. Think of the difference between an electrolytic cap in the signal path compared to a film and foil cap. In the first few seconds, it seems like the air bearing is missing high frequency information, and in some sense it is - no high frequency distortion caused by bearing noise. But after listening for a minute or less, the difference (and preference) is clear: music from the air bearing is more natural and more musical.

After extended listening, it also turns out that the air bearing TT is less fatiguing (actually, not at all fatiguing). Furthermore, singers with unfamiliar accents or poor diction are more understandable. I conclude that bearing noise is a problem - and since I could hear bearing noise in the big new Technics DD, making it much inferior to the NA, it was easy to pass.

Imagine playing your expensive audiophile records on this thing
