Guys, that's an awsome point. I'll definitely keep that in mind when I start next level (AP1). I thought they embed the messages in the alpha/theta section, delta has no use of subliminal msg. Do you actually hear your voice or is it embeded like Super Longevity 2nd track? But now they are switching to autofonix, I'm not sure about how this is different, Bill says it's a significant change - maybe you guys can shed some light. Maybe I'll get your cds Nick. But my AP will run for at least a few more months, I have been using it for 2 months.
