Bi-Wire Jumpers

I Just made experimentation about Biwire and use of Jumper. And I am not sure about biwire speaker cable is as good as single wire with good jumper ? What I have notice is after a few weeks with two pair of good speaker wire (one pair with banana BFA and the second pair Spades) the result is: good details music more in front. I return to one pair with spades connecte to the bass speaker binding post, with jumper to the mid tweeter speaker binding post, result: best intigration of instruments, much more balance music, musical timbre, less in front music as if it is a little center back, I think its more homogeneous music.

My next step, would be overkill, if I use the second speaker pair with BFA banana, also connected to the bass speaker binding post.  There is a little difference between the two pair, one is Straightwire Crescendo II and the other is Crescendo III.  More to come.

Only absolute comparison is between identical cable used as jumpers or bi-wire. 

My speakers have Cardas binding posts I use the silver jumpers that came with the speakers.
