There's been some controversy about whether the Console Emulator actually does anything, and the usual (true) response is that it's cumulative when you add it to all the tracks in a project.
However, when bouncing down to a final two-track mix, insert the channel (not bus) A-Type Console Emulator in the master bus, set the Trim to around +1 to +2 depending on how the level going into the main output bus, and set drive to 2.5. This gives the audio a useful lift and some extra definition.
To test, position your mouse over the CE power button, close your eyes, and click so many times you don't know if it's bypassed or not. Then click a couple times, still with your eyes closed. It should be obvious which version has the enabled CE - I was able to identify it 100% of the time, and the audio definitely sounded better with the CE in place.
I recommend against using the bus version of the CE because it doesn't have a Trim control, and you need to turn it up a bit to obtain the desired result.
