Main differences between AM6 and its refresher

[Dzemoo]

I noticed that the volume is more important than the hours listened. Louder volume creates more and obvious results. I also noticed a difference in us vs masked, masked seems to work on the subconcious level of understanding the message behind words and sentences while us seems to work on the emotional level giving you the feeling of what it is like to be the expression of the programing. Us gives me better concentration but is also causing more resistence. Us seems to get decoded instantly but dont last as long as masked, while masked seems to work time released.
