If you want to read "the" book on sound reproduction, this is rather indisputably it: https://www.amazon.com/Sound-Reproduction-Psychoacoustics-Loudspeakers-Engineering-dp-113892136X/dp/113892136X/ref=dp_ob_title_bk https://www.amazon.com/Sound-Reproduction-Psychoacoustics-Lo... The book is backed by quite a few decades of research and controlled listening experiments with trained and untrained listeners. It really is authoritative. Dr. Toole is also very generous with his time on various audio forums and YouTube channels. So by all indications, you are also supporting a pretty decent human being.
