how do you gauge and judge "timing"?

In life timing is everything.  I guess it’s important when listening to music too.  I immediately thought of time alignment between speaker elements when I read the original post.  Appreciate the definitions posted.  Time has  come today - Time.  Now I’ve also got the Pink Floyd intro playing in my head which isn’t a bad thing.  

So sorry “PRAT” started right here during the early days of hi-fi in the UK according to @mahgister 

Naim and Linn started something here if the PRAT thing did actually originate from them with a marketing hype in mind. There’s been loads of advertising garbage spilled forth over the years to get an ‘edge” over competitors, to peddle an idea that suggests that their product is better than the others. It’s a question of intelligence or experience to hear and identify if it’s true or not.
 

But the real meaning of a “PRAT” in the UK, long before the hi-fi hype angle can not be disputed….. A simple minded foolish person, or idiot.

Judging hype and knowing what it really is, or just blindly accepting it as true can determine if you are a PRAT.

I trust acoustic concept. PRAT is not one...

 For sure i dont know the English  slang though...

There is no slang in philosophy or science books...

"At the origin though this concept of PRAT made sense more than nowadays refering to turntable timing accuracy...For sure if you own a turntable you can claim that it gives you PRAT...

but the marketing of turntable cannot be extended  with this expression to describe our sound qualities impression in a system/room only in a very subjective and limited way for sure if you own a turntable ..."

Exactly, We are talking about what may essentially be a "distortion" similar to that of a tube amp. It’s a distortion we can hear and which we happen to find congenial. If turntables have a higher chance of exhibiting PRAT because of groove errrors, groove drag, needle wander and such then it is likely that solid state systems declared PRATTY also exhibit those irregularities, i.e. they are not perfectly rendering the music data. It’s subtle, and it sounds more authentic - like real humans playing with their neurological faults on display.
