I do believe that effective shielding against noise IS perhaps the most valuable function that any wire can provide that is most likely to make a difference in sound quality in many cases. I've found Pangea 14 series to accomplish this most effectively, as designed and advertised. I'm sure many others do as well. Its not rocket science and need not cost a fortune IMHO.
The fact that Pangea and I am sure others CAN accomplish this for fairly modest cost is something worth noting.
