You have made 3 statements, All Days sound the same, you can measure the differences between Dacs and therefore predict what it will sound like, all Days don't measure the same. Surely these statements are mutually exclusive?
I’m going to focus on how you are going about this rather than the substance of your questions, which whether you intend them to or not are bordering on the vexatious.
I have been extremely clear and specific about what I’m saying, yet your responses do not engage with what I am saying at all, but instead focus on developing tangential arguement from semantics rather than substance/produce non sequitur points and falsely summarise what I have said.
This approach is often used by someone who is arguing in bad faith and for whatever reason is using logical fallacy and theatrics to give the illusion on a discussion, and often to convince their own side that ‘they won’ because they were able generate a large amount of words. It’s not uncommon for people to do what you are doing in good faith because they haven’t been taught to think critically. I have no idea what your intentions are of course, however, a persistent refusal to engage with what is being said and the persistent presentation of false dichotomy, straw man and non sequitur argument are often a good sign of a bad faith actor. If that is the case then I expect you to declare victory very soon,
So I say again;:
The scientific consensus in all related matters should lead us to conclude that electronics don’t have a sound if well engineered. The total lack of evidence in the form of controlled tests showing that people can detect even 00s of dbs of difference supports this rather than undermines it. Case closed unless evidence of either a change in the scientific assumptions triggered by a new theory or empirical evidence (from a controlled trial) is produced.
You may wish to notice that I have made specific efforts to ‘iron man’ your argument-ie by spending time checking what you mean etc. This is because. I’m not looking to point score or prove you wrong, but to understand what you arguement is.
So far I am taking your argument to be that you can hear differences between dacs in a feat of hearing that any engineer or scientist would regard as impossible...
