Truly balanced decoding and amplification
The K7 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.
Democratized high-quality balanced amplification couldn’t sound better
Using the same THX AAA 788+ amplifiers as the K9 Pro, the K7 is capable of outputting 560mW into a 300Ω load at 1% distortion, and 2000mW into a 32Ω load at 1% distortion. This ensures both low and high impedance headphones are powered with aplomb, and most importantly lets you experience musicality that’s sure to tug at your heartstrings.
Dual AK4493SEQ rich and delicate overall sound
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.
Robust decoding capabilities take a trip around the music world
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.
RGB indicator lights for a colorful entrance
The RGB indicator lights are capable of displaying single colors as well as mixed colors, with a unique light flow effect during power-on/off or input switching. Dazzling and vivid light effects give your desk some much needed spice.
