Well, yes. I understand what he means in his text. I thought it was a somewhat different view of the topic of blind listening tests. Thats why I posted the link. What I find harder to figure out by myself is what possible objections, if any, there could be to his arguments.
I think maybe one objection could be that - yes 16 bits are enough if dither is used in a correct manner when 24 bits studio masters are downsampled to 16. But, you can never know if the 16 bit file you buy is treated in best possible way. With 24 bits, a master original, you are free to do your downsampling yourself if you wish, or just leave it, and you don’t have to trust someone else to do the downsampling in the best possible way. But as
