Kieran will answer you "the spec is right even if it tells you that 2+2=5". ;-) My answer is: profile, don't speculate. Q: "the user has quality audio equipment that can play full range" K: "the user knows that there is an option" D: quantified damage to the sound (subjective impression translated to an approximate value) d1: quantified damage of playing compressed range on quality equipment d2: quantified damage of playing full range on poor equipment d3: quantified damage of having to set an option E(D) = P(K)×d3 + P(¬K∧Q)×d1 if compression is the default E(D) = P(K)×d3 + P(¬K∧¬Q)×d2 is compression is disabled by default. So basically, you need to provide convincing estimates for the ratio between P(¬K∧Q) and P(¬K∧¬Q) and the one between d1 and d2. Regards, -- Nicolas George
