Power supply for turntable, is it worth?

Hello everybody,

I was actually thinking about trying the Clearaudio Accu Power supply to use with my EAR phonostage. In my view the fact of having a steady DC tension shold remove all the problems relative to the main pollution correct? Has anybody tried this solution before? If so, which results did you get?

Of course advices/thoughts/opinions or only guesses are more than welcome.

Thank you
