FiiO K7 BT balanced desktop DAC and headphone amp with Bluetooth, THX amplification and USB Read more.
The FiiO K7 BT is designed as the new baseline reference for balanced desktop DAC and headphone amplifier combinations within the FiiO lineup. Positioned between the well-known K5 Pro and the more advanced K9 Pro, it targets demanding listeners looking for a compact yet capable solution for desktop listening. Its form factor and connectivity make it suitable for workspaces, home studios, or minimalist HiFi setups where space and performance both matter.
Internally, the K7 BT adopts a fully differential audio architecture, processing each channel independently from digital conversion to amplification. Dual AK4493SEQ DAC chips contribute to a smooth and musical sound signature, while the THX AAA 788+ amplifier stage is engineered to deliver stable power across a wide range of headphone impedances. The XMOS USB decoding solution with dual clock management is designed to handle multiple audio formats reliably, helping maintain clarity and timing accuracy during playback.
Wireless functionality is handled by the QCC5124 Bluetooth chipset, enabling support for high-quality codecs such as LDAC and aptX Adaptive. This allows users to enjoy low-latency wireless audio without sacrificing overall sound integrity. Additional customization options, including firmware updates and EQ adjustments, are available through the FiiO Control App. Combined with its CNC-machined aluminum chassis, compact height, and subtle RGB lighting, the K7 BT is a practical upgrade for anyone seeking flexibility and refined desktop audio performance.
