Lifters ForGetting Cables Off The Floor, Worth It Or Snake Oil

I personally believe there are certainly more important things to focus on to realize system improvements than 100.00 fuses and keeping cables off the ground. I have witnessed some philes directing too much attention on factors that realize less benefit than other  tweaks that IMO would be more beneficial. Room treatments, speaker placement vibration isolation would be among them. In my experience, at the recommendation of my dealer as recommended emphatically by the speaker cable, ic manufacturer a physicist BTW for whatever it's worth, just do it says he. I did and clearly noted greater clarity it wasn't a leap of faith to hear this . Quite simple, out of wood to match my equipment rack. Didn't cost me anything but time.  Enjoyed your comments teoaudio. 

Abrew how deep does the trench need to be? I’d be a bit concerned about the foundation, wouldn’t you? Would definitely require a structural engineer to do the calculations and further analysis to determine pro/con. Sure would make for a great rabbit warren though.
