Key Features
- The FiiO K17 is the first to feature a discrete amplifier circuit, utilizing an OP + transistor current-driving headphone amplifier design. It is equipped with the On Semiconductor MJE243G/253G classic complementary pair, enabling high-current, low-impedance output. The balanced output power reaches up to 4000mW+4000mW, effortlessly driving both large headphones and in-ear monitors. The sound is smooth, natural, and melodious, delivering a pleasant listening experience.
- The device uses the AKM flagship DAC chip combination AK4191 + AK4499EX*2, with each AK4499EX handling one channel. This is paired with an 8-channel to 4-channel LPF design to reduce common-mode interference, resulting in better separation and dynamics. Additionally, it features a fully separated digital/analog structure based on a new design technology, incorporating the newly developed "DWA ROUTING technology" to further purify the background and enhance resolution.
- The FiiO K17 is equipped with the professional DSP chip M21586Q and the high-performance ADC ES9821Q, complemented by a custom-designed ultra-low phase noise femtosecond crystal oscillator. It offers a 31-band professional-grade high-precision lossless PEQ adjustment function across all input modes. This allows for simulation or correction of headphone frequency response curves.
- The FiiO K17 supports multiple input options, including single-ended line input, balanced line input, USB decoding, Bluetooth decoding, optical decoding, and coaxial decoding. The USB decoding uses the XMOS 16-core chip XU316, supporting 768kHz/32bit, DSD512, and full MQA decoding. Bluetooth decoding is powered by the Qualcomm QCC5125 chip, featuring Bluetooth 5.1 and supporting aptX HD, aptX Adaptive, LDAC, and other codecs. For streaming, it supports Roon Ready and AirPlay, giving you access to a vast array of streaming sources. Local playback is supported via external USB drives and portable hard drives, allowing you to enjoy your precious collection of audio files.
- The K17 features a custom-designed 3.93-inch LCD screen, allowing for quick switching between various settings and functions via touch controls. It also includes five independent control knobs, supporting one-button standby, and enabling fast adjustments for volume, gain, output, and more. The device comes with an infrared remote control for convenient long-distance operation, allowing you to easily switch between work modes, select EQ settings, and adjust volume.

Best praise vs top criticism for FiiO K17
Top Criticism
+15 pts“If I may impart a hard lesson. Do not stack anything on top of the K17. The heat build up caused permanent bias drift in my unit, which now constantly clicks into protection mode even on low gain. I've ordered an external fan as a last resort in the hope that it may alleviate the problem somewhat. My advice is to keep it on its own for top ventilation and make sure it is raised up high enough for bottom ventilation.”
