<em>Objective</em> fidelity is a measure, based on a computable,
mechanical metric, of how carefully an output matches an input. For

total harmonic distortion when amplifying an input signal; this claim
is easy to verify given proper equiment, and any number of testers are
likely to arrive at the same, exact results. One need not listen to
