    Hello there,

    This is probably a known topic, and Iโ€™ve done lots of searching around the web but Iโ€™ve been unable to resolve it.

    I recently bought a pair of nice Beolab 9s. Looks great and sounds even better. But, Iโ€™m struggling with humming while playing music. At lower volumes the humming really ruines the experience as itโ€™s quite noticeable. This is my setup and what Iโ€™ve tried.

    I have connected the 9s to an Argon Stream 3, from Powerlink to one RCA-plug, on each speaker. Cables are Mk3, brand new from BO. All power is connected to the same socket. This is humming a lot.

    I’ve also tried same cable, but with a mini-jack adapter at the end, and connected it to my MacBook. This is actually the setup that is the most quiet, but not at a level where it should be. Also, I can hear a noticeable difference when removing the charger from the MacBook, as itโ€™s more quiet.

    Does anyone have any experience on this and what I can donnext? I honestly thought the active Beolabs would be more or less plug and play

    I would strongly suggest a new cable as the first step.

    An update in case this thread shows up in a search:

     

    I replaced the cables, no difference. Turns out it wat the streamer, Argon, that was the source of the humming. I replaced it for a Sonos Connect, and everything is perfect.
