Have no hum,noise, i use shielded quality cables
It's just that 3 meters is not long enougth, i don't just want to have it the shortest way, i want to have it long enough so i can use it without having it over or under my pc.
4 meters are okay, but no one makes it in 4 meters, 3 or 5 meters is the standard, unless it's custom made cable and that is not cheap. Over 30$, i can easily get 5 meter of some decent cable for 15£, just not white (theres only a limited white cable in a decent thickness and 4 or 5 meters for 15£) and since i especially wanted genelec's in white (and have it it white) for many years, i don't want to ruin the synergy (if possible) by buying a black cable, but not for 30£.
