I have just moved to a new apartment and I'm getting electrical noise feeding back into my powered monitors (Adam A7X). This is high frequency noise bleeding in from some noisy dimmable lights, making the tweeters buzz. All the audio equipment is connected through a Furman PST-8D, but this doesn't seem to mitigate the noise at all. The connection from DAC->Monitors is balanced (and quite a short run), so I'm confident it's not line noise picked over the cable.
Additionally, and tangentially related, I have a small m-audio monitor connected in another room, and this was making a popping sound when the master bathroom fan was turned off (I am well aware that electric motors can act as a large inductor and feed current back into the mains when the field collapses after power off). Oddly, there was a monster power conditioner (HTFS500) already installed in the apartment on that socket, and it does much better at reducing/eliminating this issue (compared to the Furman).
I was wondering if something like a tripplite isobar would be effective at isolating the monitors from this sort of nose on the mains. If not, is there something that may be effective? I was surprised that the Monster unit outperformed the Furman, and now I'm wondering what my best options would be.
As a side note, the monster units are now discontinued, so trying another one of those is out of the question (the current unit is run in wall so I can't move it to test on the Adams).
Thanks for the help!
