Capacitors in line with TT motor - Upgrade?

"Does not have direct bearing on the actual audio signal, just how the power is regulated to the motor"

That's classic.

Undertow: In my experience (which is admittedly limited to one example, but I don't think this a controversial statement), increasing the capacitance of the motor regulation can indeed have a direct impact on the audio signal, as you put it (irrelevant that the cap is not within the electrical signal path -- a TT/cart, as a transduction system, also has a mechanical signal path which is equally important), and not only in the case of the regulation being overtly faulty beforehand (mine wasn't). I have no idea whether this particular table would benefit (or yours), mine did. However, my comment was more on a theoretical level, just to point up that what you wrote came out sounding wrongheaded IMO, perhaps unintentionally, but still it couldn't be further from the truth to imply that motor regulation in a TT doesn't directly bear upon the resulting audio signal.

Ait: Now you're getting in over my head, I didn't engineer the upgraded power supply that I added to my TT, I just bought it and did the listening tests. I guess I owe Undertow an apology, as much as his actual words seemed off the mark, it's true he was writing in answer to your question about improving capacitor *quality* alone, not quantity, and though it's not inconceivable that this could have some effect as well, in that context I can see why he'd make the remark about the cap not being in the (electrical) signal path. Yours is a question for those with expertise I don't have.

My table is a Technics SL-1200, quartz-PLL servo speed-controlled with a low-rpm DC motor, so the comparison isn't exactly straightforward. The capacitors in yours could be there simply for powerline filtration.
