@Starship Krupa I believe what has been considered proven in the way past is that when all things are equal (pan law etc.) between the then tested DAWs on pure audio (i.e. no use of any FXs) they always null tested out.
Now Andrew Scheps' observation (if true) could shape a null test between Ableton and any other DAW (purpoted to not have any inbred processing).
I personally believe that Mixbus/MIxbus32C would not null to any of my other DAWs because they advertise that you are by definition getting a Harrison console, which is different for Mixbus vs Mixbus 32C, right in the DAW.
