  • The FiiO E10K USB DAC Headphone Amplifier is designed to be a high quality, portable solution to improve your laptop’s audio quality. It features a PCM5102 DAC chip, capable of handling PCM files up to 24-bit, 96 kHz resolution. It is optimized for a low-noise floor when engaged by using a selectable bass boost and low-pass filter allowing you to customization based on your audio tastes.

    DAC Chip

    The internal DAC chip is a PCM5102 which can handle up to 24-bit/96 kHz resolutions.

    Effectively improve the linear internal filter and reducing delay which improves audio quality with no phase shift and reduced silence interval on changing tracks.

    Low Noise Floor

    The unit has been improved to include an optimized low-pass filter and selectable bass which allows for an incredibly low noise floor.

    Amplification Stage

    The E10K features a LMH6643 amp, designed for superior transient response and driving power.

    Portable Design

    A brushed aluminum shell provides compact and durability, perfect for when you’re on the move.
