Traditionally, headphone amps have been afterthoughts -- relatively low-cost circuits built into receivers, computers, portable media players, etc. After all, even with relatively insensitive headphones, the amp usually needs to put out no more than 50mW -- 0.05W -- to drive headphones to loud volumes with no audible distortion. But with headphones’ recent surge in popularity, and the concomitant growth in the number of hardcore headphone enthusiasts, many manufacturers have been putting serious design effort and resources into their headphone amps.
