Great posts Teo. As on the money as it gets. Waiting to hear the counterpoint from the pseudo-scientist skeptics, but guessing the same old arguments will be put forward.
I use lifters in my system. The original thought was to use them to properly dress the cables (i.e. make sure there are appropriate distances between cables, and to ensure power cables cross speaker and signal cables at 90 degrees where possible, etc.). Apparently some of the deep thinkers here find no value in that. Plus, it makes everything look more organized and that is a consideration for some. To each their own. I never bothered to compare the sound before and after. They were inexpensive, and they more than accomplish the cable dressing as I wanted. Any sonic improvements above achieving appropriate spacing and routing would be icing on the cake, and their is no evidence that it hurts the sound. Their are certainly cheaper options to experiment with than what you are looking at as others above have suggested. Give it a try for yourself.
