Ran into Bill Low recently and he said when single wiring with jumpers it CAN matter which post you use…who knew? Bill knew (!)…My previous speakers were single wired due to the designer's recommendation (Alan Yun, Silverline Prelude speakers), and my current Sonist Recitals are biwired per design recommendation…with speaker cables recommended by Bill during that conversation (apparently single biwire cables should have disparate runs to deal with isolation benefits…he was right again!). Coherency all around. Note that I made a pair of what I thought were groovy "better than stock" jumpers for the Preludes, and they sucked. The supplied brass strips sounded better.
