Biwire Cables: Two Seperate Runs or Single Run


Can someone explain the advantages/disadvantages of using a single biwire run (e.g. 2 terminations on the amp side and 4 terminations on the speaker side) vs. using two seperate individual (2:2) runs? Thanks.

Thanks for the insights so far. It seems like there is some contradictory opinions, as John Risch thinks two separate cable runs is superior, but simulations on Audioengr's site suggest a combined biwire cable is better. Sonic_genius - by "mono-wire" do you mean two separate runs rather than a premade biwire cable.

Nikkidanjo, I am asking what is the difference between biwiring with two sets of wire versus the special bi wire cables that have on set of connectors at the amp end and two sets at the speaker end. I'm perceiving that this is the question that other posters are answering.

Thanks Again.
Many single wires can turn your rack into a bowl of spaghetti. On the possitive side, single wires can assure that all speaker drivers are getting the proper current or grade of metal. Biwired speaker cables on the other hand split the cable down the middle. Half goes to the woofer, the other half goes to the squawker and tweeter. Since the woofer uses the most current to drive massive amounts of air, shouldn't the woofer get most of the wire mass? Tweeters are more sensitive to metal impurities and should get a better grade of metal. I'll use biwiring when cable companies realize these requirements for different drivers.
Many spkr mfr's will tell you that bi-wiring is nonsense
(Sonus Faber, Genesis, & Dunlavy to name a few).
Great way to sell more wire.
Separating the lows and highs when they both originate from the same point?
Laughable.

Somehow the description of bi-ampable has morphed into bi-wireable.
Probably because bi-amping is a costly option that few want to do, while bi-wiring
is a less costly option, but not an option in the same league.

Bound For Sound had a very good article on this subject in a recent (within the last year or so) issue.
They elaborated on what we have been telling people for years on this, but few listen, as
many audiophiles love to believe those that push hype, which if enough people believe it,
seems to often become the rule that many follow in the audiophile world.
