which is a better match for best results

I get the opportunity to hear mix and match equipment in a variety of settings, I would suggest sticking with one brand of equipment, that way they are voiced the same. Attempting to tailor a sound to get the best results is difficult to do under the best circumstances.

I am sure cables make the difference in any system. Excluding the best metal conductor, silver, is kinda weird. Kinda sounds like a snake oil experience.
