Headphone Preamps

The FiiO K7 BT is a USB headphone amplifier and DAC featuring a dual AKM DAC and THX AAA 788+ amplification. Compatible with 32-bit/384 kHz PCM and DSD256, it offers high power output and both balanced and unbalanced outputs. With its digital and analogue inputs, LDAC/aptX HD Bluetooth and gain controls, it stands out as a comprehensive solution for high-fidelity audio.

ARTICLE N° 124415
The FiiO K7 BT builds on the design of the K7, adding a QCC5124 Bluetooth module compatible with LDAC, aptX HD, aptX Adaptive and aptX Low Latency. This makes it easy to stream music from a smartphone, tablet or computer, whilst maintaining sound quality.

Its architecture is based on a dual AKM AK4493S DAC, ensuring independent conversion of the left and right channels to minimise interference and maximise the signal-to-noise ratio. It supports PCM streams up to 32-bit/384 kHz and DSD256.

Amplification is handled by the THX AAA 788+ module, capable of delivering high power output with extremely low distortion and an extended frequency response. The K7 BT features a 4.4 mm balanced headphone output and a 6.35 mm unbalanced output, with an output power of 2000 mW into 32 ohms in balanced mode.

Three gain levels ensure optimal compatibility with a range of headphones. Its connectivity options include USB-B, optical, coaxial and RCA, as well as an RCA line-out or pre-out for integration into a hi-fi system. Understated and compact, the FiiO K7 BT combines power, precision and versatility in an accessible format.
