Novice here. Just bought a tacky little diy headphone amplifier kit.
I've got pretty good access to components and I was wondering if where was anything I could do to this to make it "better"

Any ideas?

Inb4: buy a decent amp

One option is getting better Op-amps. The NE5532 is cheap and will make music but something with a higher slew rate will generally make music sound a bit better. The OPA637 is the oft-recommended top-shelf op-amp but you could halve the price and get a AD843 with comparable performance.

So I can just swap out the NE5532's with OPA637, do will I have to use a different connector?

Negative on both accounts, it's a pin-for-pin swap. And actually looking at this closer, you may want to go for a OPA627 since it is more stable at unity gain which this amp has.
