Seriously? No-one else thinks so except.....well, you know who you are.
For anyone else saying that redbook is great without even thinking or knowing what type of converter he has in his DAC, he is then "full of it"?
Come on, give us all a break.
The OP is enjoying redbook very much with his Aurender but now that he is told Aurender is delta sigma, he is going to enjoy redbook less because ....." Delta Sigma will just mutilate it like it does to Redbook"?
I don't think so.
