to bi-wire or not?

hifiman5, fair point. It would be true if you leave the jumpers in place as some are suggesting.

I've gotten very good results with "diagonal" bi-wiring using jumpers. FOr example the red speaker cable connector goes to the red treble terminal and the black goes to the black bass terminal, then the jumpers connect the other terminals. This is Nordost's preferred connection method--they no longer make bi-wire cables, shotgun only....

Stringreen has ended the discussion: if the speaker is designed to be bi-wired, then bi-wiring will optimize sound reproduction. But, a cable capable of being bi-wired (designed to be bi-wired) is in order. The classic example of a bi-wired speaker is the Tannoy Westminster Royale SE/GR series … which is  (SE version) the speaker I use. Cardas bi-wires cables BECAUSE THEY ARE DESIGNED in such a way as to be capable of being bi-wired. I'm poised to replace my Cardas with MIT Magnum M1.5, which MIT bi-wires if ordered in a bi-wired configuration. If a cable isn't designed to bi-wired, it cannot be satisfactorily bi-wired. 

Andynotadam … but Nordost will bi-wire their cable if requested. I asked them this question about two weeks ago ($600USD)' to bi-wire a set of Vahalla 1 non-bi-wired cables. They can do so because the cable has the capability of being bi-wired. Not all cables are capable of being authentically bi-wired.
