Well designed, low powered receivers can sound more dynamic and powerful than competing units with two to three times the power. This can happen when a receiver has less current capability. An amplifier's current capability is a function of power supply engineering and storage capacity. Standard amplifier ratings are determined by connecting an amplifier to a precise 8-Ohm resistor, such an arrangement incurs low level demands for current. Amplifier Power measured in watts, amplifier power is used to drive speakers.
More power generally provides a clearer sound as well as an increase in loudness.
However, other features can influence clarity in addition to power. Amplitude Amplitude is the strength of a signal, usually measured in decibels for an acoustic signal or in voltage for an electrical signal.
