Hi Deej
I read the 2nd link you provided. A lengthy read, but quite an interesting story. I also checked some items in the Yahoo search term link you provided, but there was quite a bit of time required to get a decent asseement of it, to which i was not prepared to commit any further.
I dont think Holosync is necesarily any more or less dangerous than other brainwave entrainment products.
In the 2nd link, Michaele was asked about his concerns about the AVS industry. I quote here, a 60 percent portion of the reponse, to which i think might be the key to your concerns. The underlined and bold wording was done by me to point to what i think is the key.

"The brain can be a very fragile instrument, and is susceptible to damage, if harmful techniques are used.
For example, one neurotechnology product may cause neuronal death, brain damage, and seizures.
Also, it's well known that attention deficit disorders, brain trauma, learning disabilities, and various cognitive dysfunctions are directly linked with too much slow brain wave activity, such as delta and slow theta.
Yet, we have a lot of psychoacoustic tapes and CDs, electrostim devices, and light and sound machines whose manufacturers are encouraging people to use them to entrain theta and slow delta, when in fact this is the last thing many people need, for this is only going to make their cognitive problems worse. "

I also provide the following link i pulled out of a google search, in order to understand a little more about the specific brainwave states mentioned in that quote.
EEG
over 15 years ag ago, i started doing Tai Chi. There was music used by the teacher, which i liked at the time. As it helped bring me into a state, which helped with the energy flows for the Tai Chi. It was a slower brainwave that i was entraining to, as far as i can make of it. I went and bought the music. From then on, I started listening to other electronic music that i entrained to. It was not Holosync type tehnology, but i readily entrained to other states through listening. Interestingly, in the link i gave, i recognise that i was very often accessing, or in the Theta brainwave state, as all the descriptions described i can heavily relate to having been through over number of years. Bordering partially into delta on some occassions..
It is only in the past 3 to 4 years or so that a substantial graduation out of listening and entraining to the various music i have been listening to in the past.
I am definitely different today.
I can not say for sure if it is this "out of balance" brainwave activity which is the result, but it sure seems like a possibility; I use to be able to read whole books sequentially up untill i started the entrainment through listening to the particular sounds/ music in the early nineties. I have wondered for years why it was that i was able to before, but then from about the mid nineties, till about 4 years ago, i struggled to go beyond reading and absorbing more than a few pages at best.
Now, after having read all of the above, and reflecting back, i really think it could be to do with Micheal's quote about cognitive dysfunctions relating to the imbalance of brainwave patterns. It has been about a year since i last listened to any Holosync type of material or the earlier Tai Chi music which i was entraining to but was not of the current entrainment technology. I am about 90/ 95 percent back to normal with absorption now. It seems that way to me.
