Making choices with setting a sound system by hearing.
Some components shall be selected with the ears. Like the speakers.
Some components shall not! Like the speaker cables.
The roll of speaker cables in a sound system is not to tweak the sound. As previously described, the cables are a pair of conductors that should pass 1:1 (transfer function) the audio content of the amplifier’s output to the speakers. Just as a driveshaft pass the motion from the engine to the wheels. Picking a thin cable, is like getting a thin (soft driveshaft) some of the engine power (horse power (=Watts) and torque (=DF) will be lost with a poor driveshaft. Some of the amplifier’s strength and power will be lost with a poor speaker cable.
That’s not the way to get a sonic difference. This is only playing on the range between using 100% of that amplifier’s potential to some part of it (sometimes as small as 20%!).
The right way, is to get the entire potential (100%). It makes no sense buying powerful amplifiers, spend money on that power and not using its potential.
Speaker cables can and should be tailored to your system, to fit its demand and enable the full potential of the amplifier reach the speakers. This is practically the say behind some of the sharing brought here. The change is significant to dramatic.
