LP12- Power Supply- Need education

Mijo, With due respect, I think the old problem with the SOTA Sapphire was that the motor was mounted on a stationary platform while the platter, of course, was suspended.  When the suspension was activated, that caused the belt to stretch and contract in time with the bounce.  This resulted inevitably in speed instability that was quite noticeable.  In fairness to SOTA, I heard or read they solved that problem a while back.  DC motor would not be as good as their latest Eclipse option, the one that incorporates the PE technology, which works on AC synchronous.

There is, as usual, a ton of misinformation and pure ’BS’ being foisted by those who really have absolutely no clue about the sound of a well set up Linn LP12.
I love this from mijostyn...’listen to a Linn platter, you will be able to pick up radio stations’..ridiculous!

The Dunning Kruger effect is alive and well on this thread and A’gon in general. I pity the OP that was looking for info on the LP12 and then watch his thread devolve into a discourse on why Linn’s are a POS. unbelievable.

Dear Bdp, I’d like to hear from Bill Carlin himself, if he really said what you say he said. If Bill did say that, of course I would yield to his far superior level of knowledge, compared to mine. But to take your point, first of all, DC is Direct Current, meaning it has no frequency; therefore it has no phase differential. So there can be no such thing as "3-phase DC". In a DC motor that operates off the wall socket, there is a conversion of AC to DC. (Teres had a DC motor that incorporated a battery option, I think.) I am guessing that AC to DC conversion may be happening in the new SOTA Eclipse motor AFTER the power supply works on the AC side to regulate speed. I really don’t know what’s going on there, but I also saw what maybe you saw on the SOTA website. It does mention the term "3-phase DC", which is an oxymoron. They’ve probably dumbed it down for us audiophiles. But most of all, if you read my earlier post, I too recommended the Eclipse upgrade, so we have no argument there. I don’t think a DC motor has inherently more torque than an AC motor. One DC motor may have more torque than another AC motor, etc. But there is no general rule. And anyway, where did I say that AC motors were superior to DC motors? (Your comment suggests that I did say that.)

I do know that the original AR X turntable was built as you say, with the motor on firm support and the platter suspended. Probably that was also the case for the Thorens TD125. (At one time or another, I owned both.) In my opinion, that’s a problem of design for suspended belt-drive turntables that has to be dealt with in one way or another in order for platter speed to remain stable when the suspension is disturbed. My AR X and my TD125 were no great shakes for speed stability. Finally, I have not been bashing the Linn LP12 or even the SOTA; I am just pointing out some issues. Nothing is perfect.
