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?

I was trapped into a "presentation" (in the late 80s maybe) at a stereo shop of why a Linn LP12 table, when compared to a Denon direct drive table, was more  rhythmically accurate...it wasn't.

Regardless of your opinion about the turntables, it easy to see how a turntable could have an effect on timing. An amplifier, not so much.
PS - A lot of reviewers call "accurate" what I call "bright hearing aids."

Don't get me wrong, please buy what makes music sound good for you, but be aware that a lot of these "golden eared" reviewers are in the "golden age" of their hearing and don't want to admit it.

I hear a difference a little like mapman was referring to. One slight addition from my perspective to add, is for me, speakers do more of that then an amplifier. so my Thiel 2.4’s and 1.2’s and Spica TC60’s have what I perceive as a better timing impact than my Vienna Mozart Grands. But amplifiers do contribute and take away from that experience.

When I go to a dealer or a audio show I cannot believe people like to hear the sound thin, metallic, and boosted high frequencies.
