If to elucidate to the final user, the essence is as follows: every electronic equipment operational “duplicates” (not quite, however it'll be clearer) .
An analog (tube) player produces a collection of "signal + noise." furthermore, if for electronic transistor audio systems the noise is a detachable part, then the lamp circuits don't separate the grain from the chaff, reinforcing (or distorting) the complete recording. From wherever it gets to the electronic equipment - from a digital or analog supply - there's no distinction. this can be the terribly "shade", that is therefore appreciated .
