Amp "timing" ?


I was reading someone raving about the impeccable "timing" of their high-end amp this morning.  I have heard this term tossed around several times recently in my dive back into highish-end audio. 

Can someone please explain what is meant by this term?  Is it snake-oil or confirmation bias?  I just don't understand how a human  can hear  a timing difference of a soundwave unless it's a 2nd+ order reflection.  

Thoughts?

There are things that might be considered timing issues in amps, but when used in the context of a review is probably referring to detail and has nothing to do with timing at all. There is this term- PRAT which is thought to be a British thing, which refers to Pace Rhythm And Timing.
But it should be quite obvious that an amplifier can't change the timing of music; IMO this has more to do with the amplifier being low enough of the bad kinds of distortion to which the ear is keenly sensitive so that the music is processed in the limbic centers of the brain rather than the cerebral cortex. There is a tipping point for this where if the unconscious brain sorts out that there is something wrong with the 'music' it transfers the music processing from one to the other. When this happens the emotional response to the music is lost or attenuated- less toe tapping...
I haven't seen any data that shows this is specific to actual time / phase effects.

I believe that what is meant is that the beats come through so transparently you get more involved in the rhythm of the music. This is probably more of a frequency / amplitude related effect than any actual time domain effect.

I just saw an instagram post by @absolutesound that says this:

"The finesse and muscle of the Naim NAP-500 combined with the Focal Diablo Utopia's speed: the recipe for an incredibly dynamic performance with eye-watering accuracy and timing."  

Why do I feel like we're being duped here.  If I told my 10 year old son to sit down and listen to the timing of this amp, he'd think the timing was awesome.  When it's really a mystical quality that no one knows how to describe.

I'm just getting tired of all the "and the veil was lifted" colour that people are adding to their reviews/opinions that have zero basis.

But I'm still open to this timing thing if it has a basis because I LOVE believing things sound different and better, I'm just not always convinced it's true.
All to do with accurate rise-time and decay of the electronics without overhang, ringing, or harmonic distortion.
