Everything Chris at VHaudio does it very careful and high end, but for reasonable cost. For example if you are into modifying your gear or speakers, he makes the best internal hookup wire around, the Teflon Foamed UPOCC (not hard teflon!). Better than the identical looking Neo-tech in my head to head comparisons.
The proper name is UniCrystal™ OCC Copper Hookup Wire with AirLok™ Insulation.
It looks like the V-Twist cable is a jacketed version of this same exact wire. It sounds good!!
