to bi-wire or not?


Looking for advice on whether to bi-wire my Joseph Audio RM22si speakers.  Am currently running Acoustic Zen Satori mono cables which I love.  My local dealer tells me moving to bi-wire cables (either Satori shotgun or Hologram II) will make a huge improvement.   I have always been under the general impression that unlike bi-amping, bi-wiring is not all that beneficial - but I may be way off base.

Thoughts?

Is your amp biwire too? My plinius sa 100 is Biwire , my Diapason is also Biwire, I get huge improvement more open and dynamic, If my amp is not Biwire , I just use quality jumpers like Nordost....
If your speaker is designed for bi-wire, the result is pretty major.  Bigger, more dynamic sound stage with better base....much greater ease.
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....
