Ready to use Objective2 (O2) headphone amplifier in a custom JDS Labs enclosure. The O2 is an open source amplifier designed by NwAvGuy, with emphasis on benchmark performance and low cost. The Custom Spec features a rear mounted AC jack for improved aesthetics. Available exclusively in black! Made in the USA.

The Objective2 (O2) is an open source headphone amplifier designed by NwAvGuy, with emphasis on benchmark performance and low cost. This item includes a fully assembled and hand tested O2 amplifier, ready for use. You will only need an AC adapter.

The O2 has created a stir in Head-Fi.org’s do-it-yourself community. After posting one too many "objective" comments, NwAvGuy found himself banned from the forums. He proceeded to design O2 for maximum benchmark performance to prove his points. It’s large and heavy, so hardly worth consideration as a portable amp, however, O2 lives up to its name.
