LM833 is considered the same thing, yet some say it is even better. Power consumption is not superb though.
Some also say NE5532 becomes even better if a few kohm resistor is connected between a negative rail and it's output, as it forces the output operation in class A. Makes sense.

Doesn't the feedback resistor noise get added into the business as well? Most frontends have rather large feedback resistors to pump up the gain, which spoils the amplifier's inherent low noise. Correct me if I'm wrong, but 5534's popularity as a PI frontend partially lies in its relatively rapid recovery for an old "standard" design?
--edit--
never mind, I seem to be tripping the bollocks, transimpedance coupled amp noise improves as the sqrt of feedback resistance!
