Like many here, I’ve followed this thread with great interest. The dichotomy between "musicality" and "resolution" is a classic audiophile debate, but I believe it often creates a false choice.
I’ve come to the conclusion that we have to accept the decisions made by the recording, mixing, and mastering engineers. We weren’t in the room when the artist directed the mastering engineer toward a specific sonic signature. Was the goal to sound good on a car stereo, or was it optimized for a high-end 2-channel setup? We rarely know.
Because of this, Harry Pearson’s classic definition of "The Absolute Sound"—actual acoustic instruments playing in a real space—is of no practical use for the vast majority of modern recordings. It’s a chasing-your-tail exercise for anything other than purely acoustic, minimalist recordings.
A More Practical "Absolute Sound"
As consumers, I believe a better goal is trying to approach what the final mastering engineer heard in their treated studio. While we can’t know exactly what that sounded like either, we do know the conditions under which they work. We can take clues from professional setups to get closer to the genuine article:
-
Room Acoustics: Pros use established concepts like Live-End/Dead-End (LEDE) and heavy bass trapping to remove the room from the equation as much as possible.
-
Active DSP & Time Domain: There is a reason many pros use active monitors. They often provide linearized amplitude response and accurate time-domain behavior. Look at the textbook step response of something like a Neumann KH 150—it’s tight, time-coherent, and revealing.
-
Controlled Directivity: Using loudspeakers with well-behaved off-axis response (both horizontally and vertically) ensures that the room reflections that do exist don’t tonally color the direct sound.
-
Positioning: Adhering rigidly to established standards (equilateral triangle, ears on the acoustic axis, minimizing Speaker Boundary Interference Response).
While most of us don’t want our living rooms to look like Sterling Sound, taking small steps to mimic the electrical and acoustical environment of the pros might be the most honest way to achieve both resolution and musicality—by hearing exactly what the creators intended us to hear, nothing more, nothing less.
