Hi Dreanmachine....
Just quickly, in my experience, you can vary the volume of your meditation tracks, to achieve different effects. I've used them on very low volume, and quite high volume. Feels very different, but neither one is "bad" or "good". It depends on your mood at the time. Inside meditation, I usually forget about the LF tracks totally, but sometimes become extremely aware of them. Again, I have no value judgement about this. It's nice to forget about them; nice, also, to be aware.
As for Optimal Learning, I always used this as a background track -- on the speakers, not headphones -- until a few weeks ago. But one day, on a whim, I tried it as my meditation track (with headphones), and was blown away by the result. It is the most peaceful "place" to meditate that I can imagine. Have been using it almost daily, and I never get tired of it.
I doubt that many members here use it that way. But, if you give it a try, you might be quite surprised.
