DAC and Headphone Amplifier · Streaming Media Receiver · Local Playback All in One Unit, FIIO K17 Is Officially Released!
This is the next generation desktop decoding headphone amplifier. It is a symphony of retro elegance and cutting-edge technology, featuring a unique design and rich functionality all wrapped in a powerful package. The FIIO K17 is not only the upgraded successor to the K9 Pro, it is also an exploration of new possibilities for a high-end desktop DAC and headphone amplifier.
31-band high-precision lossless PEQ
The K17 features an M21586Q DSP chip which is capable of double-precision 64-bit floating-point calculations, and runs at a high 360MHz clock frequency. This chip is complemented by a high-performance ES9821Q ADC as well as a specially customized ultra-low phase noise femtosecond crystal oscillator. These three components allow the user, in all modes, to utilize the 31-band high-precision lossless PEQ. The PEQ is designed to ensure the audio signal is still of high fidelity even after being processed.
When adjusting PEQ on the K17, PCM 44.1k~96k signals can be originally processed. Fine adjustments of audio parameters are thus possible, allowing for adjustments such as a gain range of +12~-24dB and a Q value range of 0.4dB~128dB. The PEQ allows the user to simulate or correct the frequency response curve PEQ settings can be easily exported, imported, shared, and saved - making it easy for anybody to use the PEQ and correct or simulate various frequency response curves of different headphones.
AKM flagship DAC, AK4191+AK4499EX*2
In the K17 is the flagship AKM DAC chip combination - AK4191+AK4499EX*2. Two AK4499EX chips handle each channel. The 8-channel to 4-channel LPF design reduces common mode interference, resulting in better channel separation and dynamics. It also features a newly designed architecture with fully separated digital/analog portions, which also incorporates the newly developed “DWA ROUTING” technology for an even cleaner audio background and improved resolution.
Discrete class AB transistor current amplification headphone amplifier
It is the first time FIIO has used a discrete amplifier circuit for headphones in the K17. This discrete circuit is of an OP+ transistor current amplification design, equipped with the classic pair of ON Semiconductor MJE243/253 transistors. It is capable of producing high current with low output impedance. The result is up to 4000mW+4000mW output power in balanced mode, nearly double that of the K9 Pro ESS. This allows it to easily drive various kinds of headphones and IEMs and to produce smooth, pleasant, and natural sound.
For more impressive features, such as the fully balanced design, 3 ultra-low phase noise femtosecond crystal oscillators, 35W low-frequency low-noise linear power supply, included an infrared remote, 2.4G/5G WIFI + Gigabit Ethernet support, and DAC and headphone amplifier · Streaming media receiver · Local playback, please visit the product page on our website.
