I have the 10ga white wires from Blue Jeans running short lengths to my Paradigms. Overkill? Yes. Any difference from old 24ga wire I had from a really old Kenwood system? Nope. However, I fully plan to dress them up in the future, I just haven't had the time to do it of late. Personally, I'm from the group of people that doesn't mind having their wires exposed, and I appreciate the opportunity to add my own personal touch to my otherwise manufactured system.
I also purchased Blue Jeans standard Bananna plug terminations (expensive imo) and terminated the lines myself. I did it all while watching a movie, so I never even noticed the "work". It goes together easily enough, just remember though that 10ga is going to be significantly stiffer and more difficult to work with then some smaller gauges.
