Markw1 - I share your frustration with selecting cables. I have found that, more than any other part of the audio chain, choosing the right cables requires experimentation. Admittedly, that can get expensive, which is why so many folks, myself included, recommend buying used cables here on A'gon, so that if and when you discover that a cable isn't right for your system, you can sell it to someone for whom it may be a better match.
Having said that, I am familiar with the sound of both Integra and Paradigm, and I believe that the Kimber 8TC you mentioned is a good, safe choice. I previously owned the 8TC's and found them dynamic, open, and reasonably coherent. But there I go, using the cable vernacular that drives you crazy. Which brings me back to experimentation...
