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?

@lalitk  Hey sorry will reach out to Archon thanks and @lak thanks for the tip on VH Audio.
I'm buying an NAD M32 integrated amp, and I'm looking at a Pangea Audio AC-9SE MKII power cord for that unit. Any thoughts, comments and/or suggestions about these would be appreciated. Also as to the Pangea Audio AC-9SE MKII power cord itself. Thanks.
I use signal cable magic power on all my sources (digital and analog) including preamp and phono preamp. Great cable for $70 and 30 day trial. 
not clear what the OP means here - if the AC cable to the PS, then No

if the DC cable from PS to the unit (e.g. a DAC) then making a star-quad type cable might be useful; IIRC they can also be bought for a small price
