First of all, let me put it out in front: I am a newbie in the world of headphones and headphone amps. I just recently had the opportunity to hear a pair of Beyerdynamic DT880 (600Ohm) driven by a competent amp, and I was intrigued. Seeking to gather more information to inform the purchase of a headphone amp, I am wondering what reasons there are not to use Class-A designs for A/C powered headphone amps. Yeah, Class-A is inefficient, but come on, a headphone amp only puts out-- what?--a couple of watts at most. The power wasted by a Class-A headphone amp will be less that a very dim 20Watt lightbulb. So the question is: what are the arguments against Class-A headphone amps?
