@neonknight ,
8 meters is a long run and might be the cause of your issues.
In your case, I would recommend some Audioquest speaker cables with DBS. Used Rocket 88, Rockefeller, or GO-4 isn't too expensive (relatively) and you might just score some on Hifi shark.
Is it possible to move your speakers closer? I have some cables I could lend you.
