It really is something where the effect is cumulative. Use Console Emulation ALL tracks, then use Quick Grouping to change the Type and Drive controls. You'll hear a difference.
I can hear a difference even on single tracks, but I think it may be a question of ear training as well. Try this:
place the mouse over the bypass button, close your eyes, then click until you don’t know whether the CE is active or bypassed. Then click and compare, still with your eyes closed. After deciding which sounds best, open your eyes to find out what it was. I wouldn't be surprised if it's the Console Emulator 99% of the time. If you don't hear a difference, turn up the Drive control all the way and try again.
