I just moved to a new apartment and when I started to setup my home theater system again I’ve decided to use Bi-Wiring for my front speakers.
My front speakers support this and up until now had a bridge connecting the elements of my speaker. I removed the bridge and ran cables to each part.
While the Wikipedia article states that from an electrical point of view there is no difference when you bi-wire or not, I did notice a difference in the sound which might stem from the very small changes in resistance which theoretically exists since the system has changed a bit.
Oh well… I guess I should fix the Wikipedia page a bit :-)
In any case, its more fun for my ears!
