I just hope that gr research keep making those types of videos on trying to teach amir a lesson, he will just keep discrediting himself even if amir doesn't respond (through someone debunking the points of a person trying to sell snake oil is always satisfying to see, just like goldensound responding to the developers of tidal MQA format) It his subscribers had a minimun of logical sense and they watched previously videos of him showing measurements of his mods for speakers and comparing with the stock models but not showing any diference in measurement for his cables they can easily see how he is not exactly a person to trust. What I found really funny is that amir used profesional equipment and there is not any minimun diference, but danny can hear a diference with his 40/50 years old ears that not matter much you have taken good care of them, those ears already had some form of wear off from effects of aging. Its just so crazy to me that there are people believing to danny ears instead of professional equipment that is desing to show the most minimal diference with a lot more precision than any human ears of any age.
