loudspeaker connections

Many hi-fi enthusiasts may not realise that significant distortion may be intro-duced into an audio signal by the con-nections between the amplifier output and the loudspeakers. In the first place, output current from the amplifier h`as to travel across several non-soldered metal-to-metal contacts, for example plug and socket connections at the amplifier out-puts and the loudspeaker inputs, and loudspeaker switches within the ampli-fier (of which more later). For minimum distortion these contacts should not only have a very low resistance, but must also have a constant, linear resist-ance.
