Bi Wire vs Speaker Jumpers

I also found the diagonal configuration using jumpers to work the best in my system.

I am running a pair of b&w 800d. Use to run them bi wired with nordost cable. Nordost now believes that the best performance is to run a quality single run then to use matching jumpers if possible. I now run nordost Valhalla in a single run with matching Valhalla jumper. Best wishes. I have also read that it is best to replace the cheap jumpers that are supplied with many speakers.

david_ten...good post!

I use B&W 802D bi-wired using dual runs of Kimber Kable 8TC and have been very pleased with the sound, but as everyone on hear (sic ) , will advise, it's your own ears that should make the decision based on your system.  Components finalizing into good amp(s), connects and speakers to make you happy is what it's all about.  Try it both ways and with different sources and music to see what you like.  

Single wired better. Sometimes.
Biwired better. Sometimes. 
Jumpers better. Sometimes.
