Smart power supplies for turntable

@lewm Same as my conclusion. Absent knowledge of how my CA table regulates incoming power, better to try a regenerator and get clean, constant power for multiple devices. While I’m not averse to trying a DIY solution, I’m not interested in damaging the turntable by using what turns out to be an inappropriate power source. And if I did end up with damage to the table, the repair could cost as much as CA’s battery supply. I will stick with my plan to audition a regenerator at home to determine if it brings an audible improvement that both my wife and I find worth the investment. We both play instruments and know how they should sound. Our two sets of ears have helped us make other equipment purchase decisions, as when we got the Audioquest Niagara 1000. 

Their battery supply lists the output as 12V, but it also says NiMh 12V, 5000mAH. As a guess only, it is a 10x series NiMh, 12V nominal, but to as high as 13.2, goes down to 10.  This then supplies the turntable that has the DC motor controller with servo speed feedback back on optical sensor.

The output of the fixed supply is 12V. This was my point with the wide range of just using a battery. Odds are it will work, properly, if reasonably designed to a volt or two below or above 12V, but the only one who can give a correct answer is ClearAudio.

For the sake of fairness I should add that I am seventy-two years old, and my hearing is not as acute as it was in years past.  Sharp eared younger audiophiles might hear more difference between the wall wart supply and the Smart Power battery supply than I did.
