This THD rise with frequency is normal for audio circuits and Bruno Putzey's discussed it extensively. Don't have a link handy but it shouldn't be hard to find his derivation that 18+MHz min is desirable. The LME49710 and 49720 are good defaults for this sort of amp (and most other audio circuits too).

Because different circuits, different loads and each individual NE5534 can have slight variations. To set the lowest possible capacitance can only be done by using oscilloscope. As you can see NE5534 is already compensated internally. With 12 pF capacitor, that will be in parallel with external. Across pins 5 and 8.
