K17-BLK

FiiO

Built for audiophiles, headphone enthusiasts, and creators who want one box that can power everything from sensitive IEMs to demanding planar-magnetics, the FiiO K17 is a professional-grade desktop DAC/headphone amplifier with a fully discrete Class-AB amplifier. The unit delivers up to 4000mW + 4000mW (balanced) with a dedicated DSP enabling a 31-band, studio-style PEQ you can tailor on the device or via companion software.The K17 can be controlled and navigated from a responsive 3.93" touch display or with an IR remote for couch-friendly control. At the heart of the K17 lies the AKM's flagship combo (AK4191 + dual AK4499EX), which handles conversion up to PCM 768 kHz / 32-bit and DSD512 over USB. Additional connectivity spans Gigabit Ethernet, dual-band Wi-Fi, Bluetooth with LDAC/aptX family, AirPlay, and Roon Ready support. Additionally, there is local playback from a rear USB drive. The rear and front panels include a wide range of connectors including USB (front/rear), optical, coaxial, RCA, 4.4mm line-in, 4.4mm headphone outputs (1/4" and 4.4mm), and 4-pin XLR adapters. There are also balanced XLR and RCA line outputs for speakers or external amps, making the K17 a powerful all-in-one hub for a modern desk setup.A Symphony of Retro Elegance and Modern Technology Designed as a new-generation desktop DAC and headphone amplifier that is distinctive in both performance and character. Merging retro-inspired aesthetics with advanced engineering, the K17 delivers a unique look with extensive functionality. It serves as the upgraded successor to the K9 Pro while also pushing into new directions for high-end desktop DAC/amp products.Specialty Chips for Hi-Fi Desktop Mixing Inside the K17, an M21586Q DSP chip handles audio processing with double-precision 64-bit floating-point calculations at a 360 MHz clock speed. Working together with a high-performance ES9821Q ADC and a specially tuned ultra-low phase noise femtosecond crystal oscillator, this platform enables the 31-band high-precision lossless PEQ to be used in every mode while keeping the processed audio signal faithful to the original signal. The DSP also supports strong output-protection and is designed to safeguard connected headphones and other audio equipment.31-Band High-Precision Lossless PEQ Powered by DEL (Dual Engine Limiter) technology and proprietary algorithms, the K17's PEQ provides dynamic range compression (DRC), dynamic range expansion (DRE), limiter, and compressor controls. It can process PCM signals from 44.1 to 96 kHz directly in the PEQ without resampling, while allowing precise tuning with gain from +12 dB down to -24 dB and Q values from 0.4 to 128 dB. Users can use this equalizer to correct or emulate frequency-response curves, and PEQ presets can be exported, imported, shared, and stored, making it straightforward to adjust or simulate different headphone tunings.Discrete Class AB Transistor Current Amplification Headphone Amplifier The K17's headphone stage uses a fully discrete amplifier design built around an op-amp plus transistor current-amplification topology. It employs a pair of classic ON Semiconductor MJE243/MJE253 complementary transistors to deliver high current with low output impedance, providing up to 4000mW + 4000mW of balanced output power, almost twice that of the K9 Pro ESS. This lets the K17 comfortably drive many types of headphones and IEMs while keeping the sound pleasant, smooth, and natural.AKM flagship DAC AK4191+ Dual AK4499EX The K17 uses AKM's flagship DAC configuration, combining an AK4191 with two AK4499EX chips-one DAC per channel. Its 8-channel to 4-channel low-pass filter design helps reduce common-mode interference, improving stereo separation and dynamic performance. The architecture also separates digital and analog sections and employs the new DWA Routing technology to further clean up the background and enhance resolution.Fully Balanced Desgin From the DAC stage through the I/V conversion, low-pass filtering, a
