My personal take
- scale - relative size of performers to venue in relation to the listener's position within that venue
- bloom - a particular way a system portrays the projection/expansion of sound events into space; presented as unfolding or blossoming in a spherical fashion from a point of origin
- sparkle - realistic sounding highs if the highs are supposed to be sparkly that is
- sizzle - mechanical/distorted highs
- dry - lacking in harmonics and overtones
- clinical vs. analytical - tough one - the former has emotions scrubbed out the latter elicits a purely cerebral response?
- clean vs transparent - former pertains to lack of distortion of sound events, latter pertains to the lack of distortion in the spaces between sound event's sources
- pace and rhythm - where the emphasis lays on the sonic envelope. Fast pace leans on attacks, proper pace is balanced between attack, sustain and decay, slow pace lacks attack dynamics. I always hated the term "PRAT" most of all, its origin being a misappropriation.
- microdynamics - low level amplitude changes within the larger whole
