I can't understand how 2 ch sound the same as 6 ch.
2 speakers can supply the same volume than 6 speakers?
Do you listen the 6 ch in a 6 speakers system?
I use headphones. The best way to explain the difference I hear would be sending you samples from the original 6ch, the MeGUI 2ch encode, and the ffmpeg 2ch encode, because my vocabulary regarding audio is limited, I can't explain myself well (even in my first language haha) but I'm not sure if that's allowed.

This is the MeGUI log using the script from my previous reply:
(I had to edit it so I could post it, I removed every "[NoImage]")
