A somewhat "controversial" topic in audio gear subjective reviewing is the reproduction of Pace/Rhythm/Timing, sometimes abbreviated PRaT. (Sometimes, PRAT with a cap. 'A' may denote A=acceleration). The topic also includes an interdependent subjective metric, dynamics.

Perhaps the seminal introduction to the phenomenon is the Nov. 1992 article in Stereophile, Pace, Rhythm, & Dynamics by Martin Colloms . I noted that this topic is "controversial" in that it not often reported in gear/equipment reviews -- especially in forum- or message-board-based reviews ... where most folks stick to the common (and, IMO, repetitive) BMTS (bass, mids, treble, soundstage). From there, some may additionally describe, e.g., a headphone's 'dynamic' or 'speed' qualities. But when asked to comment on PRaT, the same reviewer responds with puzzlement, smug ridicule, or ignorance.

Pace/Rhythm/Timing -- or PRaT -- is something I'm particularly sensitive too. It is one of the first attributes that I notice the presence or absence of in audio gear, like headphones, all else held equal. I even notice it in slow music, like adagio or lento movements (the Colloms article above goes into this a bit).

Because of the apparent "underreporting" of the "PRaT" phenomenon as important audiological subjective metrics -- and even some hostility as to its importance or even its existence -- I'm wondering how much its perception is genetic. This may be like genetic sensitivity to perfect pitch:

Or, more simply, the PTC genetic bitterness test from high-school biology class?

Pace, rhythm and timing are all sensations that come about from stimulii far, far above audible thresholds.

So, I'd have to submit that being unable to hear them would more or less indicate that one is hearing massive distortion of the painful sort, or alternatively dead silence.

Not sure what you mean by "far, far above audible thresholds"???
IMO, more distortion hinders pace an rhythm because it can corrupt micro-dynamic markers (micro-dynamic markers may be thought of as metronome events) .
