HAVE CABLES EVER TAKEN YOUR SYSTEM FROM SOUNDING JUST OK TO SOUNDING GREAT? Experiences ?

Cables are not a "belief"... their functions are supported by electrical principals and physics. This must be one of the top arguments of all time, but if we throw out the extreme stupidity involved with using "lamp cord" at the low end and then cables that cost thousands at the high end, we enter a realm of reality of where there are clear benefits given by the best conductors, shielding, terminations, solder, soldering process, etc. Will any of this make an audible difference, probably not in most cases. Is there a difference??? Yes, it is there, and I think of it this way, if I use the best possible gear that I can afford, I'm pretty sure that is a component I really do not need to worry about in my system. People will argue this to the death.

Are you really the Devil?

We are told our gear and cable make good antennas for RFI: cellular towers, home wi-fi, home security cameras, digital TV, two-way radios, police radios,  powerful airport transponders--all make up the "fog" that occupies and clouds your music-signal pathways.  Good cables provide better shielding.  Better copper, such as OCC, has fewer grain boundaries and inclusions that distort the signal.  Believe what you want because you are told so, but there is no knowledge in this area without first-hand  experience.

I'm certain the devil is much more fun than me ;-) 

Once the ganfet amps came in the door cabling in general became much more of an audible factor for me.
