LME49600: Can I use LME49600 as a buffer prior to a summing amplifier?

Part Number: LME49600
Other Parts Discussed in Thread: INA217, LM4881

Hi,

I am using INA217 as the pre-amplifier followed by an attenuator that works as the volume control. I'd like to use a buffer after the attenuator and right before a summing amplifier (I also would use INA217 as the summing amplifier). Given LME49600  will not feed the speaker, should I still use LME49600 as the buffer in the design? I was wondering if the high output current rating of LME49600 makes it to be only a good candidate to driver speakers and not necessary to be a buffer before a summing amplifier.

If not, Do you recommend other low-noise high-fidelity op-amp that can work well as a buffer in this design? 

Best Regards,

Mehran
