It's a good looking model, and I think that it by far has enough detail to produce a realistic render with the right lighting and render settings.
Judging by the button in the middle, I can see that you've got some sort of outdoor environment around it for reflection, which is alright. I would choose an indoor scene, though, since that's where you'd normally find a stereo, and it'll have more details to reflect.

this video to learn about global illumination in Lightwave and 3D graphics in general.
You'll notice in your image that some of your shadows are entirely black, which is unrealistic. The GI tutorial that I linked to above should help you out with that.
You could also use a bit of ambient occlusion, which will make it shaded darker in the cracks and crevices, making it look more realistic.
If you feel so inclined, please do post whatever improvements that you make to this when they're done. I'd like to see.
