I know you are making a joke but I thought I would reply seriously
anyway. With a short cable, it probably doesn't matter what the cable
is and getting one for a few dollars is fine. If you are going 25
feet, I would get a fat cable. Cable loss can be approximated by the
cable size so a 1/8 inch dia cable may be OK for a 3 ft cable but I
want a 1/2 inch dia for a 25 ft cable. They have all of these at
monoprice. Obviously the nitrogen gas injected dielectric stuff is a
joke. Too bad people actually fall for it.
When I was getting my audio system set up it was speaker wire that was
the big deal. I found it hard to believe that the wire could make a
difference so I modeled different configurations on SPICE, a computer
modeling program for electronic circuits. I found that the speaker
wire did have a calculatable effect on the dampening factor of the
amplifier, much to my surprise. What you want is high capacitance in
the speaker wire. The best way to get that and what I used was 4
conductor wire with the diagonals tied together so you have +-+- going
around the cable. You also want thin insulators rated for audio
voltages and not house current. That gives very high capacitance at a
low price. Just thought I would throw some things out there.
