Yes bi-wire them. Every thing gets better when you use 2 runs of good cables..try some Morrow Audio cables. They wont break your bank and they are invisible.
Bi-wire: is it worth it?
I am about to buy a sweet set of used martin logan stats. They have four terminals, and can be bi-wired. Someone has suggested I should bi-wire them. However, this would come at an additional cost, as I would have to buy new speaker cables. Does bi-wiring make a noticeable difference?
