Accusing people of being deaf, especially old audiophiles, is not an argument because too much people are included; and assimilating numbers to phenomenon and reducing them to it dogmatically is more than bad science it is bad philosophy, ignoring the structural complexities of human hearing to reduce it to some very specialized engineering field concerning a very special kind of dac, is not convincing but reflect prejudices....
I make my own controls devices for the embeddings of an audio system with great results, even being old audiophile myself, with success... I bought nothing from the market except after hearing the results.... I devise my own electrical grid device, and my own mechanical control for the speakers, and the many devices i use for active acoustical controls and not only passive one are all homemade, then the "deaf" old audiophile i am smile at your dogmas by the number and this completely free accusation....
All that comes not from super hearing capabilities but from my listenings experiments for 2 years with my ordinary ears....Audio is NOT reducible to some engineering very specialized book about some very special kind of dac....I am perhaps deaf and old but not completely gullible....
Abraxalito made great remarks .... Thanks to him.....
My best to you both....
