Thanks for the replies.
The science suggests that by utilizing a single wire that is biwired (2) connections to (4) connections that you are lowering resistance at the point of the crossover and the binding posts and pushing that all the way towards the amplifier, not sure I buy that, but the theory sounds good....
I guess the only real way to get an answer here is to attempt to run single wires with jumpers and then run biwired cables and go back an forth. Problem there is that different wires will sound different, different speakers will work 'better' with certain types of wire and so on........
I see many offerings for jumpers here on agon and some of then get quite expensive. I ask myself why would someone purchase single-wire cables and then go through the trouble of purchasing jumpers when the alternative of just purchasing biwired cables is there from the start.
My local high end shop suggests the following:
Purchase the highest quality of single-wire you can afford and then utilize jumpers (aftermarket, after you have thrown away what comes with the speakers). They feel the science of biwiring without utilizing 2 amplifiers or amps not designed to bi-amp is more sales that fact.
What I have found is that everyone seems to have an opinion.
