FiiO KA17 High End Dongle Amplifier with Dual ES9069 DACs (Black)

Product description

• Outstanding performance - Handling USB duties in the KA17 is the 16-core XMOS XU316, rarely found in audio dongles. This chip features lower latency, more stable signal transmission, and better compatibility than typically used USB control chip. And when paired with dual crystal oscillators, the KA17 is more than capable of handling various digital audio sources with various sampling rates.
• Parallel output, Big boost in power - With sufficient USB power supply input and desktop mode enabled, the KA17 s four THX headphone amps work together in parallel for greater current and overall power output. The result is up to 270mW+270mW power output for single-ended out, and up to 650mW+650mW power output for balanced out.
• All-new THX AAA 78+ headphone amp design - The THX AAA 78 headphone amp proved itself in the mid-to-high-end M11 Pro and M11 Plus players. Now, the even newer and upgraded THX AA 78+ features in the KA17. Inside the KA17 are THX AAA 78+ headphone amplifiers, with 8 op-amps working in parallel in a 4-channel fully balanced configuration, allowing for not only greater power output but also more detailed and realistic sound.
• Multistage HiFi audio circuit - FIIO engineers were cleverly able to adapt the audio circuit designs of mid to high-end digital audio players to the compact KA17. With its high-precision handling of digital audio signals, thanks to the dual crystal oscillator clocks and high-performance DAC converted to analogue signals output by a robust analogue section consisting of LPF voltage amplification, BUF current expansion and headphone amps working together in parallel, you can be sure that the KA17 can reproduce the detail and dynamics in your music as well as a serious digital audio player.
• Separate digital and analogue boards - The digital and analogue portions of the audio circuit lie on totally separate circuit boards in the KA17, each board equipped with a shielding cover for total isolation. This ensures that the digital and analogue portions of the audio circuit do not interfere with each other, enabling accurate processing of audio signals.
• Independent Type-C power supply - The KA17 features two USB Type-C ports. One is the typical port used to connect to other devices such as phones, tablets and computers. The orange port on the side is designed for use with an external power supply. When an external power supply is connected to this port, the KA17 can achieve higher power output and better performance without consuming the battery of your phone or other connected device.
