The starquad geometry of the Canare StarQuad 4S11 conributes to EMI-
RFI reduction, and a resulting quieter background than one would get
using plain copper wire in a non-starquad geometry. Of course, one
could buy plain copper wire, run it through Teflon tubing, and weave it
into a starquad configuration and have essentially the same thing as
Canare 4S11...minus the string insulation and outer jacket, but for $.69/
foot at Markertek.com, the time one saves buying the real thing seems
worthwhile.
