Sometimes life happens. And you find yourself away from your home rig, or your home rig is gone period...as is your home. And you need to listen to "Don't Think Twice" by Dylan over and over, but the soundcard in your laptop isn't cutting it even though your JH13s otherwise sound awesome. Or you find yourself without power or worse after a hurricane and the only thing that can ease your mind is some tunes from your battery-operated portable rig. Then you realize, yeah, portable amps/DACs have a place in this world because right now I could really use one.
