I do think different drivers can help accentuate sound. I mean, if I made a headphone using the driver that come with electival engineering kits and have it tuned bery similarly or exactly to an hd 600, its going to sound like shit conpared to an hd 600 because the driver will get everything loud enough but lack texture, bass will sound like simple thuds with no detail and high hats will sound blunted lacking any stayong power. Granted, the difference among actual headphones is smaller but still noticable.
