+1 …. Nailed it
One size does NOT fit all ….it is entirely a bespoke system preferred termination TBD. It’s a synergy thing AND emphasis added on the difference from bi-amping.
Some speaker brands favour bi-wiring in THEIR bespoke models ( eg VANDERSTEEN) … I’d listen if so …. whereas in my personal discussions with the prez of REFERENCE 3a for the best approach in my B system REF 3a standmount purchased from factory, it was his opinion an entirely a waste of money with no audio improvements to biwire his speakers , and just stick with hi-end OCC copper jumpers with single run cables
Contemporaneously, CHORD CABLES dropped making biwire termination in favour of single runs and matched junpers.
Similarly, NORDOST on their website leans toward as good as you can afford single runs with jumpers … and even has a blurb on diagonal biwiring connections
MY EXPERIENCES
I had a full loom NORDOST FREY in a prior system. Experiments in MY system for biwiring in a trial basis was a bust. Single runs and jumpers were the preferred choice for me …. Big time ….
TAKEAWAY
as @erik_squires pointed out, this is a bespoke hands on bespoke experimentation journey … full stop. Your speaker manufacturer manual is a preferred start with merit . Otherwise , it’s a trial and error exercise with no “rules “.
