Single vs Bi-wire Speaker Cable

Yeah, I’d have to vote for the better cable with good quality jumpers. 

I can only speak to my experience with bi-wired Vandersteens, and they recommend true bi-wire (not one cable set up with internally divided wiring)... TWO separate cables. They don't like using one cable with jumpers, if true bi-wire is available. FWIW.

I used to like two separate cables but when I tried some jumpers of the same quality as my speaker cables, I never looked back.

All the best,

I like to eliminate the biwire option from my speakers (although this precludes bi-amping which is a different question).  Then use one large gauge high quality cable.

I suspect most of the occasions where biwiring helped, the speaker cables were undersized.

I’m also in the bi-wiring is a downgrade camp. The key is to use a good jumper and not the usual low quality ones that come with most speakers (which many compare bi-wiring against hence thinking it’s better).
