Importance of power cable for Turntable?

One more thing that may or may not be nonsense is that I’ve heard that the Gryphon’s power regulation is “so good” and resilient to noise that differences in high end power cords with this brand is not as large as with other amplifier brands.

No idea what turntable you are considering but maybe rather than an expensive pc, consider a dedicated speed controller which may well have more sonic impact.

If your tt of choice does not already come with a nice speed controller of course.


I have a Nottingham tt and added a Walker speed controller ( home made pc, as all my equipment has tbh) and this made a decent SQ improvement imho.

YMMV.

@nyev, remember, the difference heard between two power cords (or any other component) is highly dependent on the resolving power and transparency of the entire system. Folkfreak's comments should be considered in light of the fact that his system is EXTREMELY revealing, perhaps the most highly so of any I have ever heard. You don't mention your loudspeakers, and they are of course a major factor in the ability of your system to reveal differences between pc's.

I tried high end power cord on my vpi sds....absolutely no difference

With all due respect to previous posters, I would not mess around with a power cord. I suggest the best TT power supply that you can afford. Comes with a cord. Nottingham's Wave Mechanic is very good, Walker is said to be good (for AC synchronous motors). For DC motors, perhaps Origin Live or ???.

It's good to isolate the phono stage from the TT motor, unless you get a regenerating TT power supply. One way is to drive the motor from the other leg of the 220VAC. Recall that power from the pole is 220VAC. That is split at your breaker box into 2 x 110VAC - two legs. Get an adjacent pair, use one for phono, one for motor.

Alternatively, you can use power supply filters and isolation transformers,

I built my own controller after buying a Wave Mechanic. It's based on a precision telescope controller out of Art of Electronics. Improvement was significant - should have been, considering the parts cost more than the assembled WM. (air bearing TT, ESL's).
