Worth reading and learning from ... although, since our ears are analog, since human hearing is not science-complete, and since 'good reproduction' is very often a question of taste (whatever "warm" means ???), the statement "Only four parameters are needed to define everything that matters for audio reproduction" is overly broad and a bit of pseudoscience itself. "No human can hear much past 20 KHz" is not a scientific statement. That said, if some salespeople were strung up with their monster cable, I'd probably be unable to hear their screams.
