Radio interference caused by power cord?

Hi guys,

When my Resolution Audio CD50 is left on, my NAD 7175PE gets very poor radio reception. If I pull the antenna wire away from the back of the unit towards the front it gets better. If I turn off the CD player the static goes away. This leads me to believe this is being caused by the power cord. Does that ring true? It’s especially interesting when this is going on because the display will show 4 or 5 bars of strong reception but there will be no sound or static depending on the station.

What is the best, least expensive way to shield this interference? I like to leave the CD50 on because it sounds much better warmed up. Should I just move the antenna wire or is this causing degredations in sound from other sources as well? ie new power cord, or a shield for the power cord, or is it something else entirely?

Thanks for your help!

What exactly do you mean by "antenna wire?" Is it a wire that goes from your receiver to an actual antenna? Or, is it just a wire, perhaps connected with a short lead to a cheap 300 ohm wire dipole. If the latter, that's probably your problem, and you'd be better off connecting to an actual antenna, located up and away from your receiver, preferably through good shielded 75 ohm cable.

@elizabeth thanks for that reco!

Would you say there is a noticeable difference between the AC 14SE MKII and the  AC 14 Power Cables?

The AC-14SE MkII has a lower noise-floor and it's a very noticeable improvement.
