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!

Zaikesman, unfortunately after promising me an audition of the ExactPower, they have not returned my telephone calls.

I guess the excitement at HE 2003 led them to promises they could not keep. Still would be nice to see what it would do in my system.

Albert,

I'll be very interested in your experiment with the Exact Power for your Walker. Please let us know what you hear.

I have the EP15A already and am about to set up a Teres with its DC motor, without the battery option (yet). Since the EP claims to control voltage +/- 1V, I'm hoping for pretty clean results from the motor. At some point I may plug the Teres directly into the wall to compare, but a new TT, arm, cartridge and stepups all in one month is way too many variables already.

I'm running the PS of my Kuzma Stabi via the PS Audio PP300 on the pure sine wave and experienced a huge jump in resolution and stability. Unfortunately, I cannot isolate the effect of the P300 on the turntable alone, as I had to run the phono/preamp via the P300 as well.

Adding the Mystic Mat took the LP playback to another level.

Albert,

Chichiuno (A'gon dealer) sells the EP with a 30 day, no-questions-asked return policy. He always returns my calls.

Somebody tell me if this is out of bounds, just trying to help. No affiliation beyond being a satisfied customer.
