Superior Sound with Flagship Dual DAC

Unlike the standard FiiO K9, The FiiO K9 AKM features a combination of AKM's brand-new flagship DAC chips, the AK4191EQ and AK4499EX, representing the performance power of AKM's digital to analogue conversion technology. This pairing delivers a truly superior audio experience, with noise levels impressively low due to the 'DWA ROUTING technology'. Enjoy your music with a level of clarity and realism that mirrors a live performance, where every detail is heard just as the artist intended.

High-Power THX Certified Amplification

At the heart of the K9 AKM's headphone amp performance is the dual THX AAA 788+, providing ample power to drive even the most demanding headphones. Whether you prefer the nuanced detail of high-impedance studio cans or the deep bass of modern headphones, the K9's dual amplifier design ensures a balanced, distortion-free experience. It's capable of delivering up to 2000mW of power at 32Ω or up to 780mW at 300Ω, making it versatile for any listening scenario.

Wireless Freedom with Hi-Res Support

Embrace the convenience of wireless without compromising on quality. The K9 AKM features advanced Bluetooth 5.1 technology, incorporating the Qualcomm QCC5124 chip for high-resolution audio streaming via codecs including LDAC, aptX HD, and aptX Adaptive amongst others, allowing for a sublime wireless listening experience with minimal latency. Moreover, the FiiO Control App connectivity elevates your control, offering a suite of customisation and PEQ options at your fingertips.

Tailored Listening with Gain Switch

The FiiO K9 AKM features a front-panel gain switch, offering three levels: High, Medium, Low. This allows you to match the amplifier's output with the sensitivity of your headphones, ensuring optimal performance whether you're using in-ear monitors or robust over-ear headphones for a customised listening experience.

Versatile Output Modes for Every Need

Choose from three output modes on the K9 AKM: Line Out, Preamp, and Headphone Out. Line Out provides a steady signal to your system, Preamp allows volume control for amplifiers, and Headphone Out caters to personal listening across various outputs, including 6.35mm, 4.4mm, and XLR-4 headphones.

Flexible Orientation and Control

Designed to be versatile, the K9 AKM comes with a stand and can sit horizontally or vertically to fit into your space. It boasts a weighty, precision volume knob with RGB lighting that provides visual feedback and 120 levels of volume adjustment for the utmost control over your audio.
