@rockymtnplantguy - take a look at this link to see what atributes make a difference in good cable design
On First appearance the Voodoo looks to be one of the best of your options, but I see they use a silver/copper alloy
- mixing metals, whether alloy or plating leads to time allignment issues that can distort the signal
The other two have some interesting approaches that sound good at first glance, but they lack in some of the basic aspects identified in the link above
I would recommend either Audio Envy ot better still, Zavfino.
Both of these brands use OCC copper, advanced insulation and more affective cables geometries
- dynamics, noise floor and clarity/details will improve with either of these two brands
Hope that Helps - Steve
