Higher sample rates can be useful for mixing, because it can prevent weird artefacts when using oversampling on newer VST plugins, hence why I'm sure he is all for it. That doesn't mean that consumers will be able to hear a difference. Even audiophiles cant hear a difference and if they tell you they are I would bet 500 euros that they wouldn't be able to pick out which is which in a blind test. I'm not trying to attack you here, but you are coming across as someone who has very basic knowledge but insists he is correct. Maybe it's just because it's a text based forum and there is no tone of voice but that is how I see it.
