Manufacturer Details

The Objective2 (O2) is an open source headset amplifier created by NwAvGuy, with emphasis on benchmark performance and low cost. This product includes a completely put together and hand checked O2 amplifier, all set for use. You will just require an Air Conditioning adapter appropriate for your region. The O2 has developed a stir in Head-Fi. org's do-it-yourself neighborhood. After being banned from Head-Fi for heated discussion, he proceeded to develop O2 for maximum benchmark performance to show his points. It's big and heavy, so barely worth factor to consider as a portable amp, however, O2 measures up to its name.
