Pops - I don't have their Zobels. These OCOS cables have been with me since about 1990 when Thiel Audio "upgraded" to more something better. I believe it was Straightwire coax prototypes with similar geometry but better wire and dielectrics. I don't know whether SW still makes such cables. Over the years, using these OCOS in many situations, with many amps and speakers, they seem to stay neutral however they're used. Coax cable claims such characteristics. I have double pairs, but have had to hotrod the termination plugs with hard-wired ends. The ends break tabs, etc. and Sumiko no longer services them.
