Id actually favour a non preamp 1HE of 2HE Version of the sq, at max something like 8/4 + some TRS in/outs.
Make ist as small and cheap as possible!
Cause lets face the facts, why would we all all choose a SQ – Pac over Qu? enhanced DLive Processing and optional Preamps + the availabilty of Option cards like waves and Dante!
Id grab one of those instantly despite having a sq 5 <3
