New Audio OP Amp Shootout

The NE5532A noise current values appear to come from the typical graphs that TI added a couple of years ago. The values in those graphs contradict what is in the datasheet tables and the graphs look rather suspicious to me: the 1/f corner frequency for the noise current is lower than for the noise voltage, which is the opposite of what you normally see with a bipolar input stage.
 
The TI datasheet says 5, the graph says 4 at 1 kHz. I used the higher value. There's also a new GBW column so people don't accidentally run into oscillation problems.
