@artemus_5 But who takes their mediocre music to a $100K system? Few, if any
If by mediocrity you mean bad mastering, I beg to differ.
Many people bring such music to their mega systems, probably most people. Because as you rightly imply, a better system gives you better sound, so you hear your favourite music as well as is possible under the circumstances. If the musicians have passed away or are not longer recording, that recording is all we have, and a good system makes that living better 😀
