Q1/Q2 and R10 are to bias the OPAMP into Class-A, not the buffer.
Both amplify the signal, the opamp is used for Voltage gain (amplification in volume), the buffer is used for Current gain (simply "ability to drive headphones").

To clarify i meant with Q1/Q2 + R10 populated. Or did you mean just the LMH6321 do not qualify? Tia To be quite honest i do understand a OPAMP(by that it amplifies a signal), but what exactly do the buffer do since it is 1:1 on the signal, is it just a very fast chip(compared to a OPAMP?) to handle all the dynamics music have, or am i totally lost
