i will twist them and see how they sound. it would look better anyway. why does this help with the high frequencies again?
A twisted pair has lower inductance than the same two wires individually.
Inductance arises from the magnetic field that surrounds a wire carrying current. The effect of that magnetic field is in effect to impose a resistance on the current in the wire; further, the amount of inductance-generated resistance increases with increasing frequency. When you twist the wires together, the inductively-generated magnetic fields partially cancel (because the currents are flowing in opposite directions in the two wires), so there is less high-frequency roll-off.
thanks for the description!
i will try twisting the anitcables. i'll try the bluejeans belden cable too. 16 feet for $10, what the heck?
Some folks claim that metal crystal structure is important (I have not yet had an opportunity to listen for this), but if you twist the wires very tightly (or bend them many times, for no good reason) you could lose the soft temper and this will not help (could hurt) the sonics. Nicely tempered wire is soft, and gets harder and more brittle as you bend it. Take a wire coathanger and bend the wire rapidly back and forth over a tight radius for a few minuites.... evenutally the wire will stiffen, then break as the metal crystal structure becomes more strained. Don't do this to your speaker wires or interconnects!
If you have hum or noise, it might help to twist a bit more tightly. This is because the amount of noise emitted or absorbed by a twisted pair is proportional to the loop area... tighter twists = smaller loops, less hum. Tighter twists also further reduce inductance and decrease roll-off (important for high-current speaker cables). Tighter twists can also increase capacitance, and this can increase roll-off in low-current interconnects.
Bottom line, it might be good to twist enough to avoid noise pickup (based on listening or noise measurements), then--if you can--try twisting a bit more to see if the high end improves.
Finally, capacitance, inductance, and noise all generally increase with wire length... if you have short wires you can probably listen to more music and spend less time fiddling and worrying.
The wire insulation is mil-spec varnish, as the wire is intended for use in winding coils. It does not have good abrasion resistance, so excessive force or repeated fiddling could cause a short.
a few too many sharp bends and the cable will break in 2 pieces.
even though this wire is softer than coat hanger, it can get brittle & break apart like one.
i don't recomend actually twisting-up the anti-cables, just place the 2 runs side by side and gently lay one run over the other and so on to make a braid. having 2 people makes this a snap and will cause less wear & tear on the cable, especially with a longer run. 3-4 twists per foot didn't seem to stress the cable whatsoever.
one nice attribute is now the twisted cables don't riiinnnnngggggg when they are struck, say with a fingernail. when separated, mine vibe like a gong for 30 secs or more. it could be felt, not heard. now the cables barely vibrate.
I've been recommending solid core twisted pair wiring as a great budget speaker cable since before the Asylum was founded. Paul Speltz added that recommendation to his website after i posted info pertaining to this subject on Audiogon quite some time ago. He initially didn't like the suggestion that i made to others to try twisting the cables together, but in the long run, he has acknowledged that the bandwidth of the anticables can be increased when configuring them as a twisted pair.
