Does Anyone Know the History of the Early Sota Turntables?

The magnetic platter is cool and eliminates most of the shipping problems, but I have to admit the practical performance of the sapphire bearing is pretty darn remarkable. It sure was a sensible solution for its time period, and still viable today. If I was buying a turntable I would think long and hard about either buying a used SOTA and having it restored or getting a refurbished one from them. Apparently Christan at SOTA is producing some videos to document the process of doing spring restorations in the field.

@neonknight I’ve been wondering about that as well. The old sapphire thrust plate and zirconium balls perform SO well, I’m not sure I understand the move to magnetic. It’s also not hard to ship the former correctly.

I’ve had many year now on various Clearaudio Innovations, with their own version of magnetic thrust bearing, and they are VERY reactive to any stray subsonic energy (right in the woofer-flapping range). It can be a huge problem in some systems (and if you think that's bad, the magnetic bearing arms made it even worse). Not sure if SOTA has mitigated this somehow; the further interaction with springs could make it better or worse. I suppose it’s also possible to use magnetic thrust just to *reduce* the load on a traditional bearing, rather than providing 100% thrust / suspension.

Agreed that modern SOTA prices & services are quite dear. When I see a clean SOTA on the secondary markets, it always seems like a smokin’ deal to me. Recently picked up a mint Cosmos that the owner had recently serviced by SOTA (still in their sealed packing) and am grateful to have it. Wonderful table. It’s a series V that has the traditional bearing, but was upgraded to new Condor motor & PSU. I’m not even sure I’d want a SOTA with magnetic bearing, and now I hear their new / upcoming top table is not even suspended? I have to scratch my head at some of the new directions.

@mulveling I have a Cosmos Eclipse and the magnetic bearing works well. No issues with suspension interaction or anything else. Now is it a sonic improvement over the sapphire bearing? That I do not know. But given what I see turntables selling for, a completely updated Sapphire for $3K seems like a lot of table.

A well conceived magnetic bearing should have no "bounce" in response to external energy like footfalls, etc.  If it did, you could have the above problems, especially on a TT with a spring suspension.

One interesting tidbit in this letter is the mention of the Panorama speakers SOTA released. There is an ad out there for a pair of the speakers on the other side of my state, and they have been listed for quite a while. If I were a collector the speaker would be worth seeking out...but I do not have room for them. Still they are tempting!

@neonknight When SOTA was marketing that speaker was during the early-mid 90s, during the short period when Allen Perkins was with them. We showed with them at CES; I think that was about 1991. Allen had moved from Minnesota to California to work with Sumiko (SOTA); he had been previously employed at House of High Fidelity here in St. Paul, who was a SOTA dealer. IIRC Allen had a lot to do with the design of that speaker. 

@atmasphere Any chance you can provide any details about their build or sound?
