Fiio KA17 Portable DAC and Headphone Amplifier Dual ES9069Q DAC PCM 768kHz 32bit DSD512 MQA

As the flagship model, the KA17 is the first USB dongle from FiiO to use the THX amplifier circuit. It uses the architecture of the new THX AAA 78+ amplifier with a configuration of 4 channels fully balanced + 8 channels of parallel connected operational amplifiers. This architecture significantly increases the output power. In desktop mode, the balanced power of the KA17 can reach 650 mW + 650 mW, approaching the power of a desktop amplifier, with more dynamic characteristics and better control, and full sound reproduction.

The FiiO KA17 uses two new ESS DACs, the ES9069Q, based on the fourth-generation 32-bit HyperStream architecture. It achieves higher performance and lower power consumption by further reducing digital noise inside the DAC, achieving a noticeably wider dynamic range of 130dB and -120dB THD+N.

The KA17 is also equipped with a professional-grade chip. 16-core XMOS, XU316, which is rarely used in USB dongles. It offers lower latency, more stable transmission, better compatibility and supports up to 768kHz/32bit, native DSD512 decoding and full MQA decoding. Paired with dual audio crystal oscillators, it can precisely adapt to different sources and sample rates.

In addition, the KA17 is one of the few USB dongles that support PEQ settings. It supports ten adjustable frequency bands, allowing users to fine-tune the EQ bands, gain level. The compact enclosure features multi-stage HiFi audio architecture, analog and digital boards are isolated to prevent crosstalk, 3-stage 10-channel power design, and comes with a case-colored faux leather case. There is also built-in thermal protection and SPDIF support.
