How does power cord affect a digital frontend?


I think it does, but can anybody explain why and how?
I could guess how current demanding amp may be affected by weak power cord, but what about CDP?

Dmitrydr, I now better understand what you are asking. I suspect that as with all conversions to dc, there are better and worse and that that cords and filters make the conversion easier.

All I can say is that on my Lindemann with a digital as well as analog ac cord, I can hear substantial difference among the cords I use on the digital as well as analog as well as an enormous improvement using the Loricraft balanced power supply.
I agree with SeanandTaylor that the laser mechanism in the CDP is a culprit in interferring with the power that feeds into the rest of the system. That is why it's best to isolate the transport from the rest of the system, and a good PC can help do this.

I am guessing, but I think the material that CDs are made with (the shiny stuff) can attract airborne RFI/EMI which can be transferred to the rest of the system as well either through the power or signal lines. I use a sheet of ERS cut into the shape of a CD to use as a CD mat and works pretty well.
