So much of this is open to interpretation that it often seems pointless. Measurements mean something, they just don’t mean everything, if that makes sense. I guess there is no real way (so far) to make a measurement of live music, analog reproduction vs digital reproduction.
I can only speak for myself here, but I am not sure that it’s the actual sound of vinyl or streaming that matters. What really matters is how it affects me. Or the mental place it takes me or how it makes me feel. What I want is a sublime feeling that I can’t describe in words, an almost ecstatic state where music becomes transcendent. Something in the music triggers an emotional response.
Yet the same thing never works twice. The variable is me. It all depends my mood. The other day, it was some vinyl records. Yet when I came back a couple of hours later it was stuff I streamed. The following day nothing moves me because I am just not in the mood. Maybe sometime I am chilled on holiday and I am absolutely loving what I am hearing over some lowfi system in a restaurant. Or even the sound of thousands of people in a football stadium singing Only Fools Rush In.
There’s little rhyme nor reason to it. How can this possibly be measured?
