What is an Amplifier?
An amplifier by definition is a voltage generating device, recreating the signal which is input to in an identical but amplified form. It will be connected to a reactive load (the speaker). The impedance of this load and phase of the signal passing through the load will vary, dependent upon the frequency and amplitude of the input signal (music).
Therefore, a perfect amplifier will be able to maintain the same output voltage regardless of load characteristics and will not alter the signal it is reproducing. A perfect amplifier when measured by the AudioGraph PowerCube would present data that forms a perfect cube. Unfortu- nately, amplifiers are not perfect. The laws of physics generally prevent it. A great amplifier is about the best one can hope for.
As you can see by the PowerCube and as you will experience by listening, your Punch amplifier is a GREAT AMPLIFIER!
