PRAT is pace, rhythm and timing. For me, I can’t just A/B a song and hear it. I have to listen for a while to one setup and then switch. I relate it to turntables because that is what I have the most experience hearing. I could hear some turntables and the music just flows and captures and holds me. Others, the music was just there- no big deal. But the sound could be virtually the same.
That was the big thing that put me on a quest for a new DAC and ultimately music server. I would listen to records for a few days, switch to digital and the sound was great but I could tell that the rhythm and pace wasn’t nearly as good.
It’s like the difference between a good and great pianist to me. The great ones make the music flow like water from the piano.
