Product Description

Replacing the hugely popular E17 model, the FiiO E17k Alpen is a portable headphone amplifier and DAC, featuring a host of input options, including optical, coaxial and USB, a feature few other portable DACs can offer!

The E17k is able to improve the sound from portable music devices, smartphones and laptops, and can be used with headphones, speakers or plugged directly into a full hi-fi system. The E17k is a very flexible and versatile product, offering USB, Optical, Coaxial and 3.5mm input, and capable of being used as a DAC, a headphone amplifier or both.

Supporting audio files up to 24bit/192kHz, the E17k is ideal for even the most discerning digital music enthusiast, and is ideal for any high resolution downloads. A stunning brushed black aluminium case, expert craftsmanship and exquisite colour OLED display contribute to making the E17 a truly premium product, both in looks and sound. Despite being portable, slim and compact, the E17k Alpen features an impressive rechargeable battery offering roughly 15 hours of use from a single charge.

The FiiO E17k Alpen lets you experience your music on the go in high fidelity and superb quality. Just because you are on the move, your music should not have to suffer. Whether that is listening to tracks from a laptop via USB or straight from a smartphone, the E17k offers greater depth, musicality and detail to your music. The E17k also interfaces with the E09K Qogir desktop headphone amplifier, to add DAC functionality and offer an improved package for desktop audio.

Can connect to the Fiio X3/X5 through digital coaxial. Play digital audio through the coaxial output on the X3/X5 to the E17k. Note that any DAC with coaxial input works with any device that has coaxial output for stereo PCM audio.
