DIY Speaker wire

Geez u guyz with all your dirty, dirty wires...just filth I say, utter filth!

Gauge 10 has resistance of 0.001ohm per foot making 10' typical cable (both ways) 20x0.001= 0.020ohm while at the same time inductor in series with the woofer is likely to have 0.1ohm "

- and what is the output imedanse of Your poweramp? Even high-ohm tube-amps performs way more dynamic & relaxed if they get some good thick solidcore. As thgick as the copper used to Connect the powercaps in Your amp, look and think..

Dynamic loss in speakercables+passive filters are the biggest loss in a hifi-system. No.2 is the loss through multicore powercables, or should I say slowstart-circuits?

Unfairlane, Tube amps present higher output impedance being power source vs voltage source that SS amps are. I was just trying to show that cable thickness is pretty much irrelevant because woofer choke has 5x higher resistance (not to mention impedance of the speaker itself that is mostly resistive). As for thick wires going to power supply caps - it is because current is charge is delivered to capacitors in very short current spikes of very high amplitude. This amplitude is much higher than any output current you'll ever see.

There might be another reason for using thick cables and it is inductance. Inductance of typical gauge 18 wire is in order of 350nH per foot while it is less than 300nH for gauge 10. It represents about 0.9 ohm of inductive reactance at 20kHz for 10' cable.
