O2 HeadAmp for Dummies
This is a work in progress, this article is by no means complete yet!
Parts selection
O2
This is the standard O2 configuration. I bought a complete kit that came with a variety of gain resistors and receptacles to make it easier to change them.- Probably THE headphone amplifier
- Well documented
- Lousy layout of connectors
- Shrouded in fan-boyism
Since I bought a complete kit and since there are seemingly multiple sellers you components may vary from those you see on my pictures. This MIGHT be perfectly fine...
oDAC
Since this build was intended for office use I wanted an easy way of getting sound from my laptop. Therefore it made sense to go for the oDAC.
Note that the oDAC goes into the space where you would normally put the batteries, so by opting for the oDAC I would have to power the O2 with an external power supply!
