This is to ensure the signal process is not interfered by power supply fluctuation. The input signal is buffered by an AD827, to reduce the dependence of the signal source as well as the interconnection cable. The low impedance signal from buffer stage feeds into volume control, and then amplified by an OPA627BP (voltage amplification) and a class A transistor buffer constructed with BC557/567+MJE243/253 (current amplification). The output is separated in 2 ways, one for high impedance headphones (direct output) and the other one for low impedance headphones (in serial with 120Ohm resistor).
