What exactly is PRaT???

A please define for me what "imaging" and "3D soundstage" mean.  In relation to what?  And why are they important?

@dogearedaudio  You and I are clearly on different planets when it comes to sound.  If you don’t understand what imaging and 3D soundstage are then you have compromised hearing and/or a compromised system not capable of producing it.  I’m guessing you have your Klipsch or Bose speakers stapled to the wall to not understand imaging or soundstage.  But, I don’t get PRaT so that’s maybe my hearing deficiency.  To each his own I guess, and that’s what makes the audio world go ’round.  

Oh, I think we're probably more on the same page than not.  I didn't say I don't *understand* 3D imaging or soundstage.  I asked for definitions.  Those definitions would have to include the word "illusion," which is what they are, illusions.  But they are definitely real phenomena.  By the same token, I believe that certain equipment affects our perception of pace, timing and rhythm in a way that is also an illusion, but is also a genuine phenomenon.

@dogearedaudio Yeah, I agree timing, pace, and rhythm, whatever that is is important and significant, but I just don’t get or sense it. When you can “see” the three dimensional images of musicians performing in a 3D space I get that. That they’re somehow behind the beat, no, I don’t get that cause the music was recorded the way it was recorded. I just don’t get what a “slow” system sounds like. But I know Linn can’t make speakers I like because they sound like shite and nasally and I can hear it 10 yards out the door. They might do PRaT but they don’t do tone or soudstaging in any realm IMHO. ,

I’m shocked, shocked I tell you, that we’re arguing over PRaT. 

Look if you can’t grok what PRaT is then maybe consider your room and how it’s messing up what you think is the sound of your amazing system.
