Neal, as with any other audio related question, ask 10 different audiophiles a question, and you will get 11 different answers. ;^)
For my $0.02, I will say that overall, I have had more success with higher quality single run of speaker cable with a quality jumper than I have had with two runs of a lower quality cable.
As for the jumpers, working with the same brand may not require any thinking, but I have also had success using two different companies also.
I try to stay with companies that have a similar tonal balance.
For instance, at this time I own a pair of Silent Source The Music Reference with matching jumpers. I also own a pair of Purist Audio Proteus Provectus speaker cables, and I am using a pair of Elrod Gold Statement jumpers.
I change these cables around when I want to shake things up a bit.
The Silent Source are very transparent and resolving, while still sounding musical. The PAD and the Elrod are both fuller, richer sounding cables.
I did try the SS jumpers with the PAD cables, but I preferred the Elrod jumpers with the PAD.
I have owned PAD jumpers previously, and while I like them, again, I like the Elrod better. In fact, I like the Elrod so much that I have been looking for some used Elrod speaker cables at a reasonable price.
To make a long story short (too late), I prefer higher quality single wire with jumpers over lower quality bi-wire. However, that is only MY opinion.
I'm sure that many will offer many other opinions that may be very different from my own. The great thing about this hobby is no one is right, and no one is wrong. There is no one single path to audio nirvana.
Good luck!
Cheers,
John
