Inside shot, showing the main PCB in the top right, with the TPA6120 headphone amp directly below it. To the left are the 4 Jung/ALW super regs, with PSU rectification/smoothing and traffo secondary fuses above, then the traffo above that.

The main PCB uses a PCM2706 followed by a SRC4192, PCM1794, THS4032 for I/V, then LME49710 for differential and then the buffer to drive the TPA6120.
