The vovox's sonorus cable line is simply perfect, i made several tests and compared this with a standard XLR cable, the difference more obvious is in the low end: the sound has more body, more "physics", it becomes "lively". It gives an ultra realistic feature overall. I advise this cable only when you have some very expensive mic like a Neumann or something. Superb.
Plus: it's not necessary to have the entire cable path made of vovox cables, even if you use only one of these, for instance between the mic and the preamp, you use like 90% if the possible improvement. And that's pretty good.
