Bi Wire Tweak

Do you guys ever read input by Jon Risch over on AA Cable Asylum? He is a regular poster and fairly knowledgeable/helpful about things related to cables, room treatment, and other topics. This link, and the related follow-ups on AA, may clear up some of your questions about the negative ground hookup.

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

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.

TO Listener57,

You got it.

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?

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.

According to my analysis, any biwire improvement is due to the returns being separated, so it might make sense to leave the jumper on the High terminals only. That is oposite to what you describe. (I assume that the crossover is implemented on the High side of the drivers. It could be done the other way around).

If you want to investigate further, try long runs of #18 speaker wires, and you might hear something.

Were you guys drinking when you tried this ;-)

Mike

can you decribe how to hook it up.??
