I'll have a look at the headamp pico. I don't really care about size. Mainly use it at work.
If you are still looking then you should also really look at the fiio e11, it is awesome. Very clean output from the line out of a Sony A845. Good RMAA results.
I gives more power than many other portable amps (like the e7 and the digizoid zo) and is cheap too (a steal).
