DIY headphone amp

I should add for the OP that I was considering this CMOY build:

From the tutorial it seemed pretty straight forward, but then I'm just getting into soldering, but thought that this wouldn't be too much to risk if I make a meal out of it.

That sure looks sweet and great photo with the K702s...I'm looking for a battery op, and as cheap as really for carting around, when I'm on train etc.... at home I'll just keep plugged into my Amp, maybe the Caiman I'd like to get.
