bjorn Posted January 27, 2022 Share Posted January 27, 2022 Lately I've noticed that my integrated amp (https://www.hifi-wiki.de/index.php/Denon_PMA-1510_AE) is producing some weird static noise. It's not a humming or buzzing, so I don't think it's a ground loop. It's kind of a quiet fluttery garbled noise. It doesn't get louder or quieter when I adjust the volume, and it's present on every channel, and it comes through both headphones and speakers. I've tried disconnecting various components, but that doesn't make a difference. I thought maybe it was coming from the computer I have connected to my DAC, but unplugging that makes no difference either. I'm pretty stumped. I've considered adding a power conditioner to plug everything into, but I'm not convinced those things actually do anything. Does anyone have any ideas? Thanks!

bjorn Posted January 27, 2022 Author Share Posted January 27, 2022 Thanks for the tip. Did it make a clearly noticeable difference in your system? Quote Link to comment Share on other sites More sharing options...
Tommy Posted January 27, 2022 Share Posted January 27, 2022 I bought mine originally to use with a VOX guitar amplifier which eliminated the dirty noise immediately. I've always used it with my Marantz TT amp so I don't really have a before/after to compare personally Quote Link to comment Share on other sites More sharing options...
bjorn Posted January 30, 2022 Author Share Posted January 30, 2022 Turns out, I was able to solve the problem by switching out which wall outlet the amp was plugged in to. I realized that I had a wifi router node with a power line connection on the same circuit, so I think my amp was picking up some of those signals.
