Synergistic Research Cable Risers?

High end cable elevators,

The cable risers definitely work. If you’re looking for evidence, look to the experts - the electricity companies use big ones all the time. You can see them outside on some places where the cables are carried well above ground height. Put them at ground height and you’d get all sorts of EMF seepage. 

Just make your own cable elevators out of wood. I did and I could not tell the difference. Maybe someone else can. Maybe they have to be made out of some space age plastic known only to NASA.

The "electricity companies" bury cables whenever possible (any new development). Audio cables might interact with some types of carpet maybe, but if cables are well made...star quad, helix, well shielded ICs, they'l work fine and little stands won't do anything...vibration raises it's pesky head when music is played, and being unnecessarily obsessed with vibration and silly things like micro arcing is an utter waste of time...with a 30 day Guarantee! 

One must take into account that there is a slight and constant bend in the cable where it is hung onto the cable risers.  Have four or five of these "static" bends per speaker cable and you have created series of resistances which when compounded does not allow the signal to pass completely unimpeded.

The obvious solution is balloons, string and helium.  Inflate the balloons with helium, and tie one end of the string to the balloon and the other around the cable.  The secret sauce here is that as the inflated balloons lose their buoyancy, at different loss rates, it creates constantly changing cable angles where attached to the string, and this multiplicity of angulation of the four or five balloons results in a smoother flowing of the audio signal.

Flatlanders, nervous nellies, and Debbie downers who have not tried this in your own house, with your own gear, you have no basis for any negative commentary.
