Suspended cables

Don, if you are worried about noise pick up from power cords just cross them at 90 degree angles. Induction will not occur at 90 degrees. I make my own power cords using 14 gauge 3 conductor and foil shield cable.
I have a 100 foot roll of the stuff. All my cables, line level, digital, speaker and power are made to exact length. There is no extra cable anywhere. 
With the power cords the shield is connected to the house side only preventing ground loops. You can run line level cable parallel and touching without any noise.   

How gentle, how wise, how curious some are, branding others, rejecting them in the deluded crowd, without experience or without being conscious that what we experience in an audio system is directly proportional to some accessible level of the potential of this same audio system and proportional also to our trained or most of the times untrained ears....

Training the ears implicate a continuous stream of experiments with the same audio system without any upgrade... After that the mind is being opened to the range of possibilities given by an audio system, where the 4 embeddings are completely controlled or not completely or half way between the two...After that an opinion has some value... :)

I arrange my cables but I don’t suspend them.  Can make a big difference and may cost nothing. 

Carpet is the enemy of speaker cables. Much static build-up. Risers will help here. Bare floors, no problem.

That's it ...Kids birthday party, rubbed a balloon on little johnny's sweater it stuck !! And now kid answers to little Susie !! Put moms high heels on 
Bam...Here's Johnny.....
