Bi-wired vs Single Termination


Recently upgraded speakers to B&W 804s and want to upgrade speaker cables. B&W has ability to be bi-wired or to use their supplied jumper at the speaker terminals. What is the adjantage of a bi-wired cable vs a single termination and use of B&W jumpers. I am looking at a used set of Volcanos with single banana plugs vs a set of Mont Blanc with bi-wiring. I understand volcano is a "better" cable but all things being equal which configuation is "better". Speakers are not being bi-amped and at this time I do not intend to bi-amp them.

Figured I would get different opinions, I am looking at used the two cables mentioned are available here for about 1K used. I was hoping for someone who has similar speakers who might have tried both and what their impression was. Also came across a interesting comment from a Bryston owner about their 9GA speaker cables ... went something like if they are OK for studios then they are good for their set up ........... makes sense .... is 1K for speaker cables a diminished return over say the $250.00 Bryston speaker cable.
What length of speaker cable do you need? There is a pair of Jena Labs Symphony cables on Audiogon, 6ft biwire that are outstanding cables. I am not the seller but really like what these cables offer. What is the rest of your system? Solid state, tubed or a mix? Also, I would agree with Dcstep regarding the general question you posed. If you go shotgun, get better jumpers, otherwise biwire is typically a better solution for most speakers that are designed this way.
I don't think using the jumper will give you the same results as a single or double biwire will.

The biwire Mont Blanc should be sufficient for the 804's, which don't have large enough woofers to need the bigger gauge of Volcano. You could have the Volcano reterminated as a single biwire, which requires just the speaker end to be done. Audioquest will charge perhaps $50-60, but then there is shipping both ways and the wait involved, although you could have the seller ship them directly to Audioquest.

Volcano may sound better than Mont Blanc, but at what price? Probably double. I think Mont Blanc is as far as you need to go in the AQ line.
