FiiO KA17 Compact Portable USB DAC and THX AAA 78 Headphone amp with Display 3.5mm and 4.4mm Balanced Output

FiiO launches the all-new portable DAC & Amp, the KA17, equipped with dual channel flagship ES9069Q DAC chipset. This portable DAC & Amp also features a robust desktop mode with 650mW+650mW output, efficiently providing power to most IEMs and headphones.

Along with this, FiiO KA17 is incorporated with a professional grade XMOS 16 core XU316 processor and allows ten-segment high-precision PEQ adjustments to tune to your preferred style. FiiO has equipped a fully balanced THX AAA 78 amp circuit in the KA17. It features an anti-crosstalk design to separate digital and analogue boards to ensure accuracy and preserve the dynamics of the original audio signal. These are some feature sets that FiiO brings to the table with the KA17.

The FiiO KA17 showcases the new ESS ES9069Q flagship dual DAC chipset. This DAC chip unit is powered by the fourth-generation HyperStream modular technology that processes 32-bit audio data. FiiO KA17 provides better performance with this DAC chipset, lowering the power consumption and digital noise compared to the previous generation DAC chips.

The dual ES9069Q DAC chipset supplies power in a four-way core design, which results in excellent performance in delivering DNR of 130dB and THD+N up to 120dB in the sound produced to you. The ESS Sabre developed DAC chipset has a day output resistance of 39ohms and supports hardware and TDM mode.

The compact yet elegant FiiO KA17 aims to deliver pure and refined sound in your music, hence it equips the all-new THX AAA 78+ headphone amp design. The THX AAA 78 headphone amp proved its capability in the mid to high-end M11 Pro and M11 plus players. FiiO featured the upgraded THX AAA 78+ in the KA17 for elevated sound delivery in your audio.

The THX AAA 78+ amp design in the KA17 works in conjunction with the eight op-amps in a 4-channel fully balanced configuration, allowing greater power output and more detailed and realistic sound. The FiiO KA17 delivers powerful, clean, and accurate audio to your IEMs and headphones with this high-end sound processing factory, the THX AAA 78+ headphone amp.

FiiO has engineered the processing core of the KA17 with the audiophile-grade 16-core XMOS XU316 integrated circuit. This processing circuit handles the USB duties in the KA17, which is not embedded in many audio dongles. FiiO is equipped with XMOS XU316 chipset, aiming to provide lower latency and deliver a stable signal transmission.

This chipset offers lower latency, more stable audio transference and better compatibility, supporting up to 768kHz/32bit, native DSD512 decoding, and MQA full decoding. This chipset also aims to provide better compatibility than usually implemented USB control chipsets. The FiiO KA17, featuring the XMOS XU316 and paired with dual crystal oscillators, is qualified to process data from various digital audio sources with different sampling rates. The FiiO KA17 aims to deliver outstanding processing performance with this circuit design.
