What an absolute beat to death subject. How they look and raising any cable off the ground for cleaning is a GREAT idea. The absolute worst, is unkept rat nests that are behind 90% of ALL AVR systems. People complain about floor noise and it's usually a simple routing issue along with cleaning up the mess, (dust included). Dust and water on cables is a BAD combination, no if's ands or buts.
I use simple W or M 2" wide handmade wooden blocks I made 30 years ago. I painted them with high gloss automotive paint so dust and oil were easily removed.
There a science and an ART behind cable management that is quite easy to do, and it takes talent to get a great look.
I did a lot of cable and hose routing on high-vibration machines for well over 40 years. It's the single largest reason for breakdowns in the Heavy Equipment market, other than regular oil/filter/fuel and a daily/PLUS grease schedule at the very least. Grease is cheap and 50-150K drifters and 30-50K breakers are greased at least 2 times a day if not more.
Routing and cable management are just as important as room treatment, both are fidelity killers in any sound system. They cost very little and they pay huge dividends in the short, mid, and long run, no matter what equipment you have at any given time.
Simple basics are always the answer. But quacking about how a person does or doesn't use cables with management isn't. What a worn out bunch of repeated crap!
I think I'll go feed my happy chickens. At least a hand full of chicken scratch makes them happier than me eatin' bugs.
