FiiO K9 AKM: New desktop DAC and amplifier unveiled

As a user-centric company, FIIO monitors the products released and optimizes them to improve the user experience. During the sale of the K9 ESS version, we carefully listened to the opinions and suggestions of our dealers and users around the world. After numerous internal discussions, we decided to develop theK9 AKM version to realize the unique sound wishes of the AKM DAC chip.

Features of FiiO K9 AKM:

• Flagship DAC combo AKM AK4191EQ+AK4499EX
• Newly added Type-C port
• Amplifier THX AAA 788+
• Dual-mode clock control
• QCC5124 Bluetooth chip
• Supports LDAC/aptX Adaptive and other high-definition Bluetooth codecs
• Truly balanced design
• Dual Voltage Linear Transformer
• Variety of inputs and outputs

 

The K9 AKM uses AKM's modern flagship DAC combo – AK4191EQ+AK4499EX. Based on new design technology for completely separate digital and analog sections, the combo DAC even includes newly developed “DWA ROUTING technology” to improve the signal-to-noise ratio and reduce noise from various amplitude fluctuations. The result is a more realistic, detailed and natural sound experience, as if you were right next to the performers.
