This is off-topic, and I definitely am not trying to defend the
"different sound" claim; but since there's not much music conversation
right now......

(1) Does the fact that a CD player's laser and transistor circuits
receive tightly controlled voltages mean that all the other circuits in
the CD player receive equally tightly controlled voltages? For
example, I'm wondering if the final electromagnet that moves the
earpiece diaphragm draws its power through the same clamping circuit as
the laser and transistors do? If not, we could speculate that 15%
higher voltage to the diaphragm's electromagnet could <...blah blah
blah...>

(2) Since no voltage regulator is perfect, could a slight difference in
battery voltage have a slight effect on the regulator's output? After
all, microscopic differences in the polishing of a clarinet's bore are
claimed to affect the final sound. Can we speculate about the musical
effect of a microvolt variation --- which only a trained musician can
reliably hear and identify? <grin>
