Just a theory:
I must have spinned over 30,000 vinyl records over the years starting from 1969. ...That's 60,000 when you flip them.
And that figure is conservative...it could easily be twice that number. * Try to estimate how many spins you had so far in your lifetime (LPs); it's not that easy.
Anyway, I spinned as many CDs.
Here's my own spin. When I listen to LPs it is indeed more relaxing, less fatiguing than spinning CDs. And I think the reason why is because it is less demanding for my brain.
There is a natural/analog continuity uninterrupted; no dots, no bits, no space to fill..all is in the grooves, the smooth flow of the needle tracking the walls of those grooves.
There is no digital jitter, no irrationality in filling the missing spaces. The waveforms have no binary numbers and easier for the brainwaves. There is no encoding and decoding.
The overall amplitude sounds free of quantification, even if the measurements suggest other orders.
It's only a theory, as compared to digital:
https://en.wikipedia.org/wiki/Digital_signal ...And it's the way I perceive it from experienced listening.
You don't know what "fatigue" (working with your brain) is until you start relaxing (with analog vinyl).
Now, it don't mean more than what I just theorized. Today you most certainly can reach audio nirvana from vinyl, and be more relaxed too.
Vinyl will do that to your brain; make of you a more relaxed person.
And that don't mean that you are perceiving less, getting less than what it can be; no, it simply means that you are more responsive in a peaceful relaxing music listening way.
There is more that we don't know than we do... I sincerely think.
? And for the record; what I said above is from long period of times in spinning one medium @ a time, and also from spinning both mediums concurrently...few LPs, then few CDs and vice versa.
And, also for the record, all spins (analog and digital) were from systems costing less than what you can pay for an 8-foot pair of speaker wires (say $20,000+).
And that, is a lifetime average from conservative music listening analysis of humble financial category. So, I just don't know if more expensive systems from both mediums would lead to different results or not; it might, and it might not...only the ones with first hand experience know best. ...Including Steve, Amir, Mike, Jack, Peter, Lloyd, David, Francisco, Ronald, Davey, Al, Bruce, John, Andre, Carl, Marty, Philippe, Don, Elgar, George, Tony, Michael, Ian, Winston, Lenny, Mark, Paul, Joe, Robert and Jeffery. ...Few more too, I cannot remember them all.
