The Auzen X-Fi™ Forte 7.1 has a separate Headphone Output Circuitry. This is implemented for the rear and front panel headphone output.

This Headphone Amplifier does not use a normal amplifier chip (IC). Instead, it uses a proprietary Auzentech-designed dedicated Headphone Amplifier. Based on the OPAMP, it has eight (8) high-end discrete transistors (buffer Class-AB type) in the headphone driver stage. This Headphone Amplifier can support up to 100mW/channel output (power), and thus you can connect any type of headphone and hear the audio you desire (compared to the line-out configuration, which supports only up to 7mW/channel). The Headphone Amplifier provides the precision of an OPAMP with a superior audio specification, while at the same time providing powerful damping and driving capability, and more dynamic sound and stability in all frequency ranges.
