Smart power supplies for turntable

How about just go with Cin. That would be more accurate.

Anything you want.

cindyment makes a great point about off center drilling. It is rampant and clearly audible. If you take a test record and widen out the center hole just 1 mm and play a 100 Hz tone you will clearly hear the pitch change. If you focus on a fixed visual reference in line with the finger lift of the tonearm you will see it wander back and forth on at least 50% of the records you play. If you can see it chances are you can hear it on sustained notes. This does not mean that turntables should not be accurate but this requirement has to be put into perspective. Just a 0.5 mm displacement will produce more wow than any modern audiophile turntable that is not defective. What is even more disturbing is there is not a pressing plant alive that can reliably drill a centered hole!  The hole that centers the grooves (stamper) is punched after a cursor is visually lined up on the runout groove. The standard for this is within 0.2 mm. This requires a lot of care on the part of the operator and a machine that is properly calibrated and maintained. 

Clearaudio does not make shabby turntables and the stock power supply probably does all the filtering and regulation required for acceptable performance. Spending even more money on an outboard power supply is not likely to make an audible difference that can be heard reliably. Your brain will think it heard it only because you spent money. Don't feel bad. My brain does the same thing.

I am the OP for the earlier thread mentioned above for the Clearaudio Smart Power 12V supply.  I eventually bought Clearaudio's very expensive power supply.  I wouldn't stake my life on it but I believe I am getting a little quieter signal out of my Performance DC Wood TT with the Smart Power 12V than I did with the pitiful looking little switching wall wart supply which came with the turntable.

Thx to @cindyment for describing issues not well addressed on Clearaudio’s website or in their documentation. I am not interested in spending $1200 for their battery power supply unless I can try it and return if there is little or no improvement or if there are better, more cost effective alternatives. I know the voltage in my house bounces around unpredictably. Even had an electrician attach a device to my panel to graph the voltage over 24 hours. The graph was relatively stable for periods of time and then would show a precipitous drop to around 113v and then move around over time, trending back to 120v. Trying to time my turntable use with voltage variations to find out if I can hear a difference is almost a fool’s errand. Seems to be time of day oriented to only some extent - summer air conditioning season when people come home from work, but other times seemingly random. I will see if I can audition a regenerator at the time of year when voltage is most likely to vary to find out if I notice any improvement to the table’s sound quality. 
 

Thx to all for your responses.
