Product description

This is the combo model of Onbective2 with DAC(Degital analog converter). You can connect PC with USB and can output from the line output(optionaly you can output from RCA). 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. With so many headphones, earphones, cables and headphone amps to choose from, it can help to know what to look for. Check out the website for reviews, comparisons, tips, specs and recommendations! The name of the website is「BUYJAPAN HOT EARPHONE AND HEADPHONE CABLE REVIEW!!」. Please check!!
