Fiio E9 Desktop Headphone Amplifier

The FiiO E9 desktop headphone amplifier offers truly stunning audio performance and versatility to headphone and audio enthusiasts. Its sleek and modern form factor, while minimalist in appearance, belies the engineering marvel within. The E9 has exceptionally low noise and distortion, providing enough power to drive the most demanding headphones up to 600 ohm with excellent dynamics and clarity.

The E9 also serves as a dock for the E7 USB DAC and portable amp. When combined, the E9 and E7 becomes a seamless high fidelity audio interface for any computer, allowing noisy internal sound cards in computers and laptops to be bypassed. With both a fixed and a volume controlled line level output, the E9 functions well as a pre-amp for driving power amps or active monitors.
