Getting cables up off the floor is a big enough improvement I've made stands for all of them, power cords and interconnects as well. It was first tested with wood, but paper or plastic cups would also work. Basically anything that gets them up off the floor is better than on the floor. Best of all by far however are ceramic insulators.
The improvement with Cable Elevators is big enough everyone notices and I've even had people say they could hear the sound change one by one as they are removed or replaced.
With your flat cables the trick would be to reduce sag by twisting them to vertical. Otherwise it would still work, it would just take more insulators. Search around on eBay, where there's a huge selection as they're sold as collectibles. I've tried various ones. They all work well and its nice to have a variety of sizes and shapes. Look around, you may even find some with slots that would fit your cables very nicely.
Also its hard to tell from the pictures but ceramic insulators are all threaded inside as they are designed to screw down to be fastened typically on telephone poles. This makes it very easy to use a wooden dowel or whatever to hold them at whatever height or angle you want.
