Any decent DIY headphone amplifiers that will run on 5V?

[drabina]

Looking for a schematic for a decent headphone amplifier that will run on 5V. It is not going to be USB powered so I can provide up to about 2A of dedicated and fairly clean power.
 
Thanks.

With that much power a boost converter would allow your +5 volt "limitation" to work with a lot of different amps....
 
Here's a thread to give you some ideas:

Lots of boost regulators here, some with digital voltage readout:-
