This is the schematic that corresponds to version 1.0 of my design. It's divided into 4 sections: the USB section (which takes USB signals in, and outputs I2S Data), the I2S DAC (which outputs a balanced audio signal), the output opamp power supply section, and the opamp circuit itself, which provides the output.
