In answer to your question about EQ.
I have had the reply on a similar question.
It will do both, however this is done in firmware and the updater will be included.
One benefit (for me) is when the unit is in Pre-EQ it will run in 24bit sound, which is the level expected by most larger venues thesedays.
If it's left in Post-EQ then your audio rates are reduced to 16bit (fine for the bedroom or small bars).
This is quite recent news, and shows ADJ are listening to their supporters.
