Sockets take the power pins on the IC that little bit further away from any on board decoupling, and add a little inductance and resistance along the way.
So good practice is to add a small cap in the 0.01 to 0.1 range directly soldered on to the IC to maintain a low impedance path at HF. Do that and you won't have problems.
The OPA2134 is a "fast" opamp for audio, but it's all relative. There are far "faster" device around.
The GBW (gain/bandwidth figure) and slew rate are related for voltage feedback devices such as here.
