I have seen a lot of ideas concerning Cable lifters

@holmz Confused by your comment about monoblock amps. The amp in that photo is a stereo amp. The speaker cables are Tel Wire cables,  which while more valuable then some are not in the "amp money" category. 

As an aside, regardless of using monos or a stereo amp, in general, you will benefit by keeping speaker cables short and using longer interconnects to the preamp or source w/volume control. In general when doing long cable runs, balanced cables are beneficial if you have balanced gear. See my system page for an example. Cheers,

Omg this has to be the best test for psychosomatic response

Perhaps, but it keeps the robovac from damaging the cables and it was a fun project to make. Cheers,

I’m just going to whip up a few on my 3d printer and call it good. If nothing else, buying one to print cable management clips and brackets is well worth the cost:)

Worst case I’m out 20 bucks of plastic. Best case I get to answer the question for threat of my life of why I have mini golden gate bridges on the floor🤣

The best idea is first to try something inexpensive to see if it works.  If it's some company marketing them with claims they cannot prove, use terms like quantum mechanics, designed with carbon fiber with engineering from F1 racing, run away.

For those who have doubts or just refuse to even consider this, how intelligent is that, I have a couple of ideas you can easily apply (in certain cases) to visualize your speaker's output. The first and easiest way is by using an APP for cell phones called ‘Decibel X’ or just ‘DB’. It is a free tool that you can use just like a frequency analyzer. Yes, it will depend on the microphone of your phone, but that can easily be remedied by using a better microphone. It takes some time to learn how to see the rapidly changing frequency charts but it works well.
 The second means of testing is IF you have a system that is tuned by 'Dirac' (Diraclive and DiracLE). This tool lets you RECORD the output of a specifically tuned sound that scans a multitude of frequencies and then provides you with a printout of the response. This uses THEIR microphone, which can also be used in the previously mentioned test with ‘Decibel X’. It will not tell you what is musically pleasant to hear, but it will provide you with an accurately tested and documented report. And I think that anyone who has utilized Dirac will tell you, that it does wonders on 'Room Corrections'.
