Hi @elizabeth thanks for your response - yes the power cord is removable from the CD player.
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!

As an additional piece of the info - on the back of the CD player next to the power input is a sticker labeled “200-240VAC”. I saw this on the photos before I purchased it and inquired with the A’goner who sold it to me - he said that it was actually a 110V unit. And it works fine indeed in my NY home - however, could this have something to do with it? |
@elizabeth thanks for that reco! Would you say there is a noticeable difference between the AC 14SE MKII and the AC 14 Power Cables? |
Got the AC-14SE MkII power cord yesterday - didn’t fix the RFI issue. It did, however, noticeably improve the CD player’s performance. Sounds cleaner, clearer with more height to the soundstage, more timbre to the instruments. I was a power cord skeptic, now I’m a believer. Thanks for the recommendation. Now to fix this RFI interference... |
