im really considering the d2000's, but need to be sure if my receiver (denon avr 791) will drive them well enough.
 
these will be my first (high-end?) headphones with pretty much only listening to the hd280 pro's.

Any receiever will drive the D2000. You only need to worry about power when using an MP3 player.
