Manufacturer Details

The Objective2 (O2) is an open source earphone amplifier created by NwAvGuy, with focus on benchmark performance and low expense. This product consists of a totally assembled and hand tested O2 amplifier, all set for use. You will only require an AC adapter ideal for your region. The O2 has actually produced a stir in Head-Fi. org's do-it-yourself neighborhood. After being prohibited from Head-Fi for heated conversation, he continued to design O2 for optimum standard performance to prove his points. It's big and heavy, so barely worth consideration as a portable amp, however, O2 lives up to its name.
