Biwiring: can you really hear the difference?


What are people's experience with biwiring, and do you really think it makes a difference over just getting a jumper?

I have used jumpers and I have bi-wired. The bi-wiring offered a much improved musical presentation. For the relatively small investment it's worth the effort. Try it!
OK... so let's say I bought two pairs of cables (4 total); my amp still only has one pair of +/- for each speaker channel. That would mean I'd have each post on my speaker accomodating two spades? Is that what people suggest?

I found that biwiring my vandersteen 3a Sigs and fives made a big big difference. Biwiring is absolutely the way to go with vans.

With magnepans I could hear an improvement, but found it to be a bit smaller improvement.
