Qualcomm QCC5124 Bluetooth chip

The K7BT headphone amps employs the Qualcomm QCC5124 to handle Bluetooth duties, with support for formats such as LDAC, aptX HD and aptX Adaptive. This chip ensures that Bluetooth connections are both reliable and quick, satisfying both the low latency needs for games/videos and the high bitrate necessary for high resolution audio.
Bluetooth format support: AAC/SBC/aptX/aptX LL/aptX HD/LDAC/aptX adaptive

THX AAA 788+ amplifier

Using the same THX AAA 788+ amplifiers as the K9 Pro, the K7BT is capable of outputting 560mW into a 300Ω load at 1% distortion, and 2000mW into a 32Ω load at 1% distortion.

Balanced decoding and amplification

The K7 BT has a six-stage audio circuit with truly balanced analog and digital sections – which helps to reduce crosstalk and reproduce music to a great extent, allowing you to better enjoy the purity of your music.

Dual AK4493SEQ

The left and right channels are each equipped with an efficient high-performance AK4493SEQ. With this DAC’s pleasant timbre, its rich and delicate overall sound will let you rediscover your music all over again

Low-noise power supply

The K7 features a power design consisting of multiple independent stages, with a voltage of each stage being regulated by low-noise LDOs. Feeding this power design is an external 12V switching power supply

XMOS XUF208

The XMOS XUF208 decoder chip uses dual clock management to handle various music formats with ease, allowing you to easily listen to many audio formats.

Variety of inputs and outputs

The K7BT contains USB, optical, coaxial, and RCA inputs. Outputs are 6.35mm single-ended and 4.4mm balanced for pleasant listening no matter the headphones.

Two gain levels

The high and low hardware gain levels allow you to easily adjust the K7BT to handle headphones of various impedances and sensitivities for a rich and consistent listening experience.
