No such thing as to much power. To much gain maybe, and that's the case with a lot of amps out here - they have way to much gain. I use my HD800s on my speaker amp so I know the Ether will do just fine. But you're right, it's more than likely not needed at all. However, I feel my amp is just a better amp than most all - if not all headphone amps out. That sure is the case with all the headphone amps I've heard thus far.
