Do you know if I change the condenser is influencing the sound with something?

If you changed the condenser (capacitor) on one speaker you would probably want to change it on both to 1: keep both your speakers the same spec so they sound as similar as possible and 2: if one failed the other is possibly gonna fail too soon.

If you replace it with one of the same specifications, it should not influence the sound.

I think the faulty caps in this case are in the power section, not in the audio path. That doesn't influence the sound, apart from the buzzing should be gone ofcourse.

The problem is comming from audio interface, I just check my monitors on a music shop with another interface, th guys from focusrite told me is possible the problem is comming from my cables, I mean, I have all my cable connected in one extension chord.

Try a power strip without ground, if possible / legal...
That would definitely break any ground loop.

Copy paste from my save list, they each address it slightly differently, but ultimately you're chasing a ground loop.

Cables wise, are you connected via balanced cables at both ends? That can help half of the time, although if everything is coming from the same electrical multi-way and balanced cables haven't helped then you need a clean box.

I've always used and recommended: https://www.soundonsound.com/reviews/art-dti

There are cheaper ways of doing it including cheaper inline adaptors (or as noted lifting the ground is a quick way to test, but maybe not longer term), but ideally you want a lift process that properly separates and cleans up the signal the way the transformer isolator process in that unit does, otherwise, those cheaper cables can end up impacting your low-end response rather noticeably or leave you without a ground, which can be unsafe.

First time I got my monitors, pc, my pc monitor in one extension chord pluged in on wall soket, so I took out the monitors and I connected in another extension chord which I plug in another wall soket, the buzzy sound has been reduced a lot now I can hear a bit if I pay attention. Maybe the qualiti of extension chord is a bit low? This is why is still there some buzzy sound?

Changing cable positions on your outlet can help.. First thing that comes to mind is grounding, is your group grounded?

Maybe try a higher end power strip like a Tripp-Lite Isobar. Any thoughts on these or just snake oil?

They don't really help in the case of a ground-loop.

OP - have you done the ground lift test yet?
