Amir has taught me nothing about audio but his site and its "pinball wizards" (deaf, dumb and broke kids) have taught me a lot about cult psychology. When one person has a crazy idea (say, in audio reproduction, measurements matter more than how something actually sounds, or everything audible is measurable by today's instruments), they are challenged by peers and the crazy idea gets rejected and the species evolves in a pro-survival direction. But when they surround themselves with other crazy people, there’s no challenge and the idea lives on because they feel social acceptance based on that idea. This phenomenon is massively dangerous and just a small version of the same idea destroying the US democracy and eventually possibly the world, namely Trumpism.
