some speakers sound better biwired.
Example: most of the B&Ws, some Vandersteen.
For other speakers it may not matter.
There are different types of bi-wire speaker cables.
Shotgun bi-wire speaker cables - 2 separate runs to speakers, but terminated into a single run on the amp end so you don't have to use 2 sets of binding posts.
Example of this cable is Acoustic Zen Satori Shotgun.
Internal bi-wire cables - terminated as a single run on the amp end, internally biwired with 2 pairs of leads for the speaker end.
Example of this cable is Acoustic Zen HologramII, the biwired version.
Then you can always use 2 totally separate speaker cables if you have 2 sets of binding posts on your amp.
Will your speakers benefit from one config over another?
The only way to find out is to try.
