I used to own a few pairs of Kimber Kable Hero HB that I really liked. The difference between the HB and the ordinary Hero is that the signal supply cable is made of pure silver instead of copper. That changes the sound significantly, perhaps in the way you are looking for. But as said by somebody else, trial and error is the only way for you to find out. Unfortunately, the HB version of these great cables is quite rare on the used market. I sold mine recently with a pinch in the heart as my new system only has single ended terminals.
Good luck !
