Two flagship ESS ES9069Q DACs and four THX AAA 78+ amplifiers in a fully balanced design deliver up to 650mW per channel from the 4.4mm output when you flick the D.MODE switch, and a second USB-C port takes external power so your phone’s battery isn’t used. A 16-core XMOS XU316 adds a 10-band parametric EQ, and a dot-matrix screen and physical buttons put the settings at your fingertips. It won a CIHE EHA 2024 Gold Award and a VGP 2025 Summer Gold Award.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-ka17-high-end-dongle-amplifier-with-dual-es9069-dacs-photo-colours.jpg?v=1791321729\" alt=\"FiiO KA17 dongles in titanium, blue and black\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eDesktop mode, taken to the next level\u003c\/h3\u003e\n\u003cp\u003eFiiO has refined its desktop mode through the M17, Q7, M15S, Q15 and KA13, and the perfected version is in the KA17.
