There are two negatives to overpowering headphones. One is that the amount of volume adjustment is so small that it would be fussy to set the desired level. The second is that the amp would be capable of blowing up the headphone (and your ears) if used improperly. This is why receivers and premaplifiers normally have a heaphone amp built into them that bypasses the regular outputs. Headphones dissipate milliwatts, not watts. There is no sonic reason to use a powerful amplifier for headphones and it is not recommended.
