The Nordost website says to avoid internal bi-wire cables, and not to use a cheaper double run...they say use the best single cable you can afford and equivalent jumpers...until you can afford a double run of their good cables !!!
Free Tip for Jumpers
If you have already replaced the stock jumpers on your bi wire speakers I found this to be a nice boost in sound quality. It was a Nordost section of Music Direct, FYI.
Enjoy!
Diagonal Bi-Wire
For those looking for maximum performance from their bi-wire speakers, Nordost has a recommendation. Connect your speaker wire to the speaker as follows: Red lead to the Red midrange/bass post, Black lead to the Black tweeter post. Then insert the Norse Jumpers as you normally would, sit back and hold on to your socks. The effect is astounding, with greater focus, detail and less haze and grain. We don't really understand how it works, but it does so try it for yourself!
