    Some noise is normal.

    Especially for speakers with class A/B amplifiers.

    If the power LED on your speakers are also a power switch then they got class A/B amps. If the LED is LED only (not a switch you can push) they got IcePower digital amps.

    If you can hear the noise within 1 meter distance but not let’s say 2 meters away it’s what I would define as normal.
