UPDATE: New batch arrived today!
The Objective2 (O2) amp was designed by NwAvGuy to have better performance than any commercial headphone amp under $1000 on the market today. He realized this goal with a DIY design that costs only $30 in parts to build.
This PCB will get you started on building this amp yourself (just add $30 in readily available parts). Detailed building instructions including a detailed list of parts with part numbers - which you can use to quickly order all the required parts - is available on NwAvGuy's website (see links on the right under Documentation).
