Musak in my pub was a CD juke-box , other than too loud at times, adequate
sound rendition. That packed up and they replaced it with an "internet"
juke-box pulling sound files off broadband. Amp speakers and wiring stayed
the same, just source changed. Now whatever sound level, the sound is
terrible, but not to the management of course. Reminds me of the vinyl days
and fluff accumulates around the needle and that fuzziness gets worse and
worse , but with that you just lift the pickup and blow off the fluff.
Hasten to add , not just me, a musician friend of mine is considering never
going in there again, What is the name for this distortion? presumably from
being compress and decompressed so sung words are unintelligible and
instrument timbre become indistinguishable from general mush.
