In order to answer you question, a few parameters need to be known:
1) What frequency, or what range of frequency are you planning to amplify?
2) How much distortion can be tolerated?
3) What amplitudes will you be generating, constant or varying?
4) Will the sine wave ever reach DC or close to it?
5) What peak to peak voltage is required on your load?
6) Will it be AC or DC coupled to the load?

Now I'm looking at an application where I may need to drive a 5 to 10 Ohm load with a sine wave signal having a Vpp of at most 32 Vdc.
