I know Bobby doesn't like silver, but I am having great results with VSM-MXs and Audio Consulting silver-wire ICs and speaker cable using natural cotton sleeves. These wires beat out hi-end MIT Oracle and Audioquest Diamond cables in my system, particularly in terms of open, transparent sound associated with the low dielectric constant of cotton. You can buy the wire and cotton and DIY, or have them made up by Kyle at Reference Audio Mods. They are inexpensive and he has demos for mail-order evaluations.
