I have never found a better console compressor for vocals than the “OPTO” that is available for SQs with the optional 5 compressor pkg. When working with post production in my Digigrid/Waves LV1 system I generally use the CPU hungry Hybrd compressor, individually customized, for each input application. However the ability to quickly set high quality resolution and needed specific values for each individual vocal mic in the SQ is about as good as it gets for SR console compression.
