Default NE5532 as a pre amp for a Szekeres headphone amp

I am putting together (albeit very slowly) a headphone amp based on this design ( with an added CCS output stage, to go inside my passive pre for my LM3875 dual mono Gainclone.

I have aquired a Low noise preamp kit from Maplins (UK) based around an NE5532 dual opamp

My question is, would it be possible to impliment this preamp into the Szekeres design? Would it just be a case of connecting the output of the op-amp to the the input of the MOSFET amp?

your Maplin link takes me to the front page.

Why do you need a preamp before the headamp?

What's wrong with feeding your signal straight to the volume pot?

It was just a general question. It is not my intention to fit it, I was just exploring the possibilites. A bit of experimentation helps the learning process .
