Just to throw you a curve, I'd suggest you consider the diagonal connection scheme as recommended by Nordost as well as some other cable companies. It's explained in their
bi-wiring jumper connection guide, and is found by many to provide the best sonic performance. While any of the connection schemes appear at first glance to be equivalent from an electrical perspective, there are differences in the symmetry of the signal path between them. Nordost finds that it "
often becomes the new default set up, offering greater air, transparency, dimensionality and subtlety." If you try it please let us know your thoughts, since your system would definitely be up to revealing these differences. Hope this helps!
