Not so sure! It might be your brain playing tricks on you!

here is the photographic evidence that proves that the arrows are indeed pointing in the right direction.

Next to the floor?  You mean you're not keeping the precious signal elevated from the horrors that dwell there? 

 

Absolutely.

The effect of the surrounding dielectric (insulator then air) on the signal flow through a speaker cable is well documented.

The effect of a randomly changing dielectric such as that which occur when speaker cables are run along the floor can affect the sound in different ways.

Cable supports, such as those illustrated, is the only safe way to reduce this problem. Make sure you match the material and the spacing to your particular cable.

Russ Andrews say nothing about that. They promote their elevators as a solution to the problem of vibration in floors affecting the signal.

Russ is, as usual, wrong on this.

Speaker cables are not microphonic, easily proved, try hitting them with something with the amp turned up, no sound or movement of speaker cones, nothing.....!

The electromagnetic field that surrounds a current carrying conductor is real and measurable. The dielectric material that surrounds the conductor will affect the characteristic impedence of the cable so it is best to avoid random changes in dielectric throughout the length of the cable. 

Since the inverse square rule applies, raising the cable a few inches off the floor reduces the effect of the floor to negligable proportions, which the only requires the listener to determine the optimun spacing of the supports by comparative listening tests.

RE: Cable flow direction

Dave, what are your thoughts about this ladder feed cable geometry that is a standard in broadcasting? Is this better or worse than braided for speaker cables and interconnects?

RE: Cable flow direction

Does it matter if I run my speaker cables directly north/south or will they be less effected by the Earths magnetic field if I run them east/west?

If any change occur, the frequency will be so low, as to be inaudiable.

Happy Easter!

To get it right, you need an expert in Fung Shui.

That's ok then. I'm a black belt.

RE: Cable flow direction

Surely with even just a few watts of power running down the cable, any change brought about by it being on the floor is going to be utterly overshadowed? Surely its better to worry about the quality of the recording than something so utterly insignificant?

Don't be silly.....!

You simply need to factor in the coriolis component for your particular latitude, a gentle curve in nominally straight runs of cable should do the trick,naturally the effects are reversed south of the equator.
