It's technical mumbojumbo that is used to design the amps and DACs that we enjoy. As I try to remind some, this is not advanced science but Electrical Engineering basics, NOT rocket science. I find it odd that some of us who do not understand this at times act like this is witchcraft. If a doctor tells me that I have diabetes and need medication, I'm not going to say that I don't feel any different and not take the required medication because I don't understand the medical science behind this.
If anyone wants to take an adventure in excess, that's fine with me, enjoy. If they make what I feel is odd claims, I'll try to provide balance.
