Here is another audioholics articlehttp://www.audioholics.com/reviews/c...-cable-faceoff
There are two general ways to make cat5 style speaker cables.A. Parallel the cables on a per sheath basis, as per the article.
1. Reduces the inductance slightly as a result of splitting the current among several conductors. Since the current is spread out a bit, the reluctance path for the field lines is longer, so the inductance goes down.
2. Increases the capacitance slightly...B. Parallel the internal twisted pairs.
(connect all stripes together, connect all solids together..This method:
1. Causes the inductance to plummet, as the twisted pairs internally are actually twisted differently to reduce crosstalk between pairs. The inductance will be approximately 150 uH / number of pairs which are paralleled.
2. Causes the capacitance to rocket, the value equal to slightly more that the pair capacitance times the number of pairs.
3. The characteristic impedance of the entire cable assembly will be 100 ohms divided by the number of pairs that are paralleled. (I've personally used this to create a 4 ohm transmission line for high speed pulses, it was fantastic for 70 volt pulses with 10 uSec rise times..not an audio application of course...)
Method B can be an issue if the amplifier is hot...high bandwidth, as the capacitance of the cable in conjunction with a load impedance which falls below the line impedance, can easily cause oscillation of the amp...not good.
Resistance of course, will be the same regardless of the construct geometry, and dependent only on the number of wires paralleled.
I believe the cable has insufficient guage, but that's my opinion. I believe the guage difference is probably sufficient to be noticeable...making a cable with adequate guage would probably give ten microfarads per foot
OH, btw..using method B completely detaches the electrical specifications from the geometry, there is no reason to play braiding games. Method A does.
