Bi-wiring?

Bi-wiring works best with lamp cord or really cheap wire. The improvement/cost ratio is pretty good then. Technically its not that good even then, it just feels like a better deal when its only $2 more than when its $200 or $2000 even though in every case its twice as much. As you can probably tell just by the numbers when you start getting into the better more expensive cables it quickly becomes first harder then impossible to get as much improvement from two as you could get by putting the same money into one better cable. 

Don't take my word for it though. Try bi-wire now while its cheap. Then try some really good speaker cables. I doubt you will ever want to go back to the lamp cord.

Best to get the rest of your system straight before worrying about biwiring. One thing I will say is that until you can justify spending money on doubling up on cables, you can get a good benefit from replacing stock jumper plates with some short runs of decent cables to bridge the terminals. I shotgun biwire my speakers and in my situation there is a benefit, but upstream electronics improvements were more impactful on an absolute basis.  Frankly, I'd even get my interconnects and power cords set before addressing the biwire issue.  Just my experience in my system FWIW. 

I got a pair of Kimber 8PR very cheap.  Spades on the amp side and bare on the speaker side.  Separated the black and brown wires into a 3/5 configuration 3-tweeter, 5 for the woofer on my Ref 3A de Capos.  Does it sound better who knows but it does sound good and i got to 15ft runs with WBT spades for 120.00

you have a wonderful friend !,,,

great speakers, like most made better by biwiring

you can read about the theory, application etc or just listen.

for best effect get the treble wires 4” away from the bass. This is called an external biwire.

have fun

enjoy the music
