Ok, bit of a strange one this but I'd like to pick your collective brains! As we all know after sales mains cable companies sat that thier leads can improve the sound of hi-fi kit for audiophiles (not commenting as I'm deaf) BUT are they also of use to those of us who want a cleaner image on our video gear (TV's and what not). Many years ago when I could still hear I used to run my big Marshall guitar amp though a surge protector an I swear it got rid of the mains hum! So my question is....how big an issue do we think mains hum / interference is on picture quality?
