Turntable Power Source Benefits


Many of the table designs today have the motor separated from the platter and run the platter via a belt or string. I see some people are going to DC to power these motors and the Teres site claims them to be a real benefit. Walker makes a regulated power supply that others have said are helpful.

How are they helpful? I can understand how a steady power supply source can provide a more stable way to deliver constant and unvarying platter speed. But how can they improve the sound other than that if the motor is already separate from the platter? If you have the TT plugged into a separate outlet, how can any power-induced problems get into the sound chain? Do motor cycles jump from the motor to the cartridge?

Help!

Gotta agree with Albert, I got the Walker for my Basis for the same reason (even worse with the Ovation, you had to change the pulley to change speeds) and have been amazed at the improvement. The speed stability is a big difference, of course, but my understanding is also that the TT motor can send a lot of noise back into your power lines which can affect your other equipment's performance; the Walker, as well as the Bylux filter I previously used, puts a stop to that. Otherwise, I'm at a loss as to why it works as well as it does, but I've taken it out of the system only once to see what would happen and put it right back in again. We tend to overstate the effect of these things, so I'll just say that while an objectivist might not be able to point out anything different, there was an ease to the presentation and flow to the music that seemed just a little lacking without the Walker. Haven't played with power cords on it yet, but I'm about to after Albert's post.
Just got back from some extended golf and saw the questions. Khaki and Mot, as to your questions I respectfully defer to Albert--I have an older model, with Valid Points attached to it and a custom "bypass" feature which my seller had put in for him (to use it without the speed control, I think). I will be trying some better power cords with both the Walker and the Basis motor, but have so far gone stock without the upgrades. Albert, does Lloyd upgrade older units?
