There are better and superior alternative of NE5532 these days. People should just move on. OPA1612 is the king in highest-end audio performance, at least on datasheet paper.
It is a decent part, and an extremely popular one found in loads of designs.
There's the saying anything you hear has passed through a pack of those before reaching your ears.
This is why it is so bad for TI to change the specs without changing the part number.
