It decodes from a computer (now also by USB-C), a phone, optical, coaxial or LDAC Bluetooth, amplifies analogue sources, and doubles as a preamp for active speakers or a power amplifier, in a truly balanced design with a dual-voltage linear transformer. It won a VGP 2024 Summer Life Style award and a HiVi Best Buy 2024 award.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/FIIOK9-AKM_1000x509_3dd7307d-a552-4156-b452-c88416ab5127.jpg?v=1767195813\" alt=\"FiiO K9 AKM on a desk with headphones\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eAKM’s flagship DAC combination\u003c\/h3\u003e\n\u003cp\u003eThe K9 AKM uses AKM’s AK4191EQ + AK4499EX, which separate the digital and analogue sections completely and add AKM’s newly developed “DWA ROUTING” technology to raise the signal-to-noise ratio and reduce noise at all levels. The result is a more realistic, detailed and natural sound, as if you were there with the performers. The circuit is balanced from the DAC to the outputs, with a signal-to-noise ratio of up to 128dB.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/fiio-k9-desktop-headphone-amp-dac-akm-edition-photo-akm.jpg?v=1791341501\" alt=\"The AKM AK4499EX and AK4191EQ chips of the FiiO K9 AKM\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eA capable THX AAA 788+ amplifier\u003c\/h3\u003e\n\u003cp\u003eThe THX AAA 788+ amplifier gives at least 2,000mW per channel into 32Ω and 780mW into 300Ω from the balanced outputs (1% THD), and at least 1,500mW into 32Ω from the 6.35mm output, so it drives low- and high-impedance headphones alike with ease.
