I wouldn't use anything other than the OPA637 or the 627 for gains of

In order to put the cat amongst the pidgeon I will admit that I ended up
preferring to use HA12017's as general purpose op-amps for audio purposes.

These were originally developed by Hitachi for use in RIAA preamps, but I
found they have a nice balance of low-noise, reasonable bandwidth, etc.
Their main drawback was that I had to experiment to determine the optimum
compensation and output bias networks as Hitachi gave no data for anything
other than RIAA purposes! :-)

Slainte,
