I'm also a friend and long time customer of Bruce. My system is very similar to yours. Belles, Exemplar, etc. For cables I use Acoustic Zen and speakers are Aerial 10Ts. I'm on kind of a search for some new speaker cables. I've gone to a pair of Belles 350As, so I no longer need the 25' pair of Acoustic Zen Matrix cables. Now something like 2 meter will do. I'm curious to know your feelings of the Shunyata Orions.
