Whether or not bi-wiring is a benefit or not remains an open debate and I know some speaker manufacturers don't do it because they feel it's a detriment (ala Dynaudio). I've run both bi-wire systems and standard runs, and I'm not sure that I can reliably say that it's always a benefit.
However, the one thing that is important with bi-wiring is that you actually use TWO sets of cables per speaker. If you use a cable that's set up for "internal" bi-wiring, all you're doing is splitting a single run in two somewhere along the way to accomodate a speaker's bi-wire connection. To gain any benefit, you really need two separate runs.
