Power cord for digital stuffs?


I have heard big power cables are no suited for digital cd or dac. Is that true? What cords are you guys using for your cd and dac?

I actually got a Meridian G808.2i recently. In the past, I have always used stock power cables with my G08.  Many people told me that big and bad cables actually thickens the sound. It was the previous owner of my 808 who told me it actually improved the sound by changing to more expensive PC.
“It was the previous owner of my 808 who told me it actually improved the sound by changing to more expensive PC“

I completely disagree with the ‘expensive’ part. As pointed earlier, a well designed cable with correct gauge (in this case 14AWG) should yield elevated performance over stock PC at a reasonable cost. 
The power cord that came in the box.   Seriously.  The power cord that came in the box.  
I have played around with several different power cables for digital gear. The best I have found is the WyWires Silver Juice II for this application.
