i owned golden hex 5 c and golden cross. i found neither warm. i sold them because they were not very full sounding in the upper mids. i have heard from others that there is a glare in the midrange produced by these cables, but without listening myself, i can't confirm such opinions.
i am not a fan of cardas cables and would not use them again.
most cable manufacturesrs do not deliberately design their cables to sound "warm", as "warm" is a coloration.
the goal of most designers is minimizing errors in frequency response, and providing as much resolution as possible, at a price point.
if you are looking for "warm" cables, i would listen to older purist audio cables, like the colossus, or the original nbs cables.
