What is the best tonearm for a SOTA Nova turntable?
Re Mijostyn’s advice on purchasing a current driven phono stage:  (1) That’s a fine idea if you plan to limit yourself to LOMC cartridges with internal resistance preferably less than 12 to 15 ohms, the lower the better, and (2) my own experience ... 
Turntables
If you have a sturdy and nonresonant shelf or base for it, Rega P10 is just fine. Go for it.

Thanks for agreeing with me, T9, but my point was not that the TT is most important; it was that flippant generalizations, like “differences between turntables…” are not helpful and may be misleading. And of course you can’t leave out the tonearm.

“Differences between turntables often comes down to the cartridge.”  The same cartridge will sound different in a different tonearm on a different turntable.  The same turntable will sound different with a different tonearm and cartridge.  These v...

Clear thinker, At least keep your prejudices vis a vis DD turntables straight.  The phenomenon you describe and object to is not at all analogous to “cogging”. Cogging is an issue for all iron core motors; look it up on Youtube. Arguably the corel... 
What is the “World’s Best Cartridge”?
An “order of magnitude “ is generally taken to describe a 10-fold difference, so the energy storage advantage of digital over analog is thousands of orders of magnitude, but for the purpose of this thread, who gives a s**t?

So you’re saying that vintage knob is wrong, because all I am doing and ever have done is to quote what is available on vintage knob?. I do realize that vintage knob is often incorrect. Which is why I prefaced my remark by stating the case “if you... 
Does Your Linn Sondek Lp12 Motor and Pulley Get Very Warm After Extended Use?
In your opening post, you said the motor and pulley were heating up after extended use. In your most recent post you say the motor and pulley are heating up when the belt is not on the turntable. Do you mean to say that the motor is heating up reg...

Excessive belt tension?

If you believe Vintage Knob, the GT2000 could be purchased with an optional high torque motor, the same motor that was standard on the X version. If I was going to use a 40-lb platter, I’d want that bigger motor.

"the presence of a large oscillating magnetic device right under a very sensitive magnetic device."  You're talking about the potential for EMI from the motor affecting the cartridge.  Why not just say it that way?  As I have mentioned many times,... 
SL-1200G/Hana ML Best Headshell
Should have noted that when you multiply effective mass times compliance and take the square root, keeping compliance constant, then the ratio of the result with a 9g vs 12g effective mass is even less different than the square roots of the two nu... 
SL-1200G/Hana ML Best Headshell
Think of it this way: square root of 9 is 3. Square root of 12 is ~3.4. So the difference between 9g and 12g is not going to affect the calculation of Fr by much.  
Analog Upgrade itch
The Steelhead is compromised by its own very mediocre output coupling capacitors.  And if you use it as a full function preamplifier, then the signal has to traverse two of those same mediocre capacitors.  Upgrade the capacitors, then you've got s...

Less rotational inertia, which is the main point of the high mass. But sure, it would “work”. Lower inertia would make it easier in the motor.
