Product description

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 suitable for your region. The O2 has created a stir in Head-Fi.org’s do-it-yourself community. After being banned from Head-Fi for heated discussion, 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.
