So your baseless claim that he can’t hear a difference is more correct than his baseless claim that he can. The countless studies on how we hear and process sound differently show that many of these hearing differences between people can be on the genetic level, due to structural differences within each ear, neuron related etc…A lot of which can’t be measured. You two could just go round and round forever. Science shows we don’t fully understand why people hear the same music differently. There are no absolutes, even with ASR’s sound measurements. Accurate doesn’t sound “better” to everyone. The constant bashing of people who don’t believe that sound or hearing sound can be summed up by Amir’s machine measurements is infantile. Understanding sound and how we perceive it may be an exact science in the future, but we a far from it today. To pretend otherwise is pure arrogance.
