A new baseline for balanced desktop sound

The K7 is a truly balanced headphone amp with THX AAA 788+ Amp technology, Dual AK4493S DACs and numerous inputs and outputs.

Truly balanced decoding

The K7 has a six-stage audio circuit with truly balanced analogue 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.

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 300Ohm load at 1% distortion, as well as 2000mW into a 32Ohm 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 are your heartstrings.

Rich and delicate overall sound

The left and right channels are each equipped with an efficient high-performance AK4493SEQ DAC. 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 a dual clock management to handle various music formats with ease, allowing you to easily listen to many audio formats.

RGB indicator lights

The RGB indicator lights are capable of displaying single colours as well as mixed colours, 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.

Worry free listening

Overheating, overload and DC protection systems ensure that the K7 always operates at its best, so you can always enjoy a wonderful listening experience in multiple scenarios.

Consistent inside and out

The K7 features a power design consisting of multiple independent stages, with the voltage of each stage being regulated by low-noise LDOs. Feeding this power design is an external 12V switching power supply. All in all, the K7’s power design can supply plentiful, clean power for an extraordinary listening experience.

Input switching with just one click

One key controls switching between the 4 different inputs, with a flowing light effect to indicate when the input has switched and is ready.

Find a comfortable volume

The high and low hardware gain levels allow you to easily adjust the K7 to handle headphones of various impedances and sensitivities for a rich and consistent listening experience.

Quality construction

The K7 features an all-aluminium alloy construction, carefully finished with CNC and other processes. Its elegant black colour is perfectly complemented by the gold accents of THX and Hi-Res Audio badges topped with a splash of colour from the RGB lights for a thoroughly luxurious appearance.
