PRaT stands for Pace, Rhythm and Timing, or simply known as “the toe tapping factor”. Some fast paced music requires a good PRaT otherwise the energy of the music is lost in the headphone/amp/system. If you want to test a system’s PRaT, try playing a fast Rock music (ie Muse) and see if you can get the energy from the music. Systems with slow pace, low PRaT will kill the energy and over mellow the...
