Bi Wire Tweak

This is how I made the connection. My speakers have four binding posts: High, positive and negative and Low, positive and negative. What I did was leave the jumper attached to the negative posts. They in effect joined the negative posts. I attached the biwire cables as normal.
It was a big improvement. The sound was more detailed but also smoother. I took the jumper off a few times to make sure I was hearing an improvement. My conclusion is the jumper stays.

One more time for those of us in the slow group. This tweak leaves the negative posts still connected, in addition to both upper and lower sets of posts each receiving their own set of speaker wires, as in traditional bi-wiring?

TO Listener57,

You got it.

I think i've seen an older pair of biwire speakers (KEFs maybe) that had a single negative terminal. The configuration was arranged horizontally like this...

I'm curious now, so I am off to play with my jumpers.

Well...?
(I am afraid of blowing up something, so awaiting conclusions from the braver-than-me caballeros.)
