Hi Papertiger
On my side of the road, I reckon that Harry Pearson of The Absolute Sound gave us a lot of interesting stuff to read, but mainly failed to take us in the right direction. Of course the ideal is to reproduce the sound as it occurred when it was recorded - but this gives us no way of prioritising the inevitable compromises in any real world system. I will refrain from commenting in any detail on the various benders he indulged in over the years, which turned out to be not much more than exercises in semantics.
Stereophile trod similar paths, and most of the audio press (particularly the ones on the right side of the road) followed along obediently.
But if you stop listening just for tonality, detail and dynamics, or worse still, for the sounds of sparrows farting outside the recording venue, or trying to tell whether the venue's shape is curved or rectangular - and just listen for how the music's rhythm grips your musical soul and takes you on the ride, you will discover that different systems do that job very differently.
PRAT is an acronym for pace, rhythm and timing, as stated above - but is about how a system gets the timing queues right. It is often misunderstood, particularly on the right side of the road, as relating to bass reproduction - as if that is the only source of rhythm and expression in music.
Whether PRAT is important to you is really a matter of musical values - but in my mind it stands for the most important element in the reproduction of music. Many would disagree with me on this point and argue that correct tonal balance is paramount. But, to use an analogy, a system that has accurate tonal balance (and even detail and dynamics) can still lack accurate PRAT, and is like a great voice on a lousy singer - the sounds made are wonderful, but that does not make it music.
It has been said before, but is worth repeating - many so-called audiophile systems are less musically engaging than the average car radio - for the very reason that PRAT is not well understood by audiophiles.
I like to think I travel both sides of the road. Most of my gear has been from the US and Canada - but the Poms have a point when it comes to PRAT.
