A new baseline for balanced sound The K7 has a six-stage audio circuit with truly balanced analog and digital sections, which helps to reduce crosstalk and reproduce music faithfully and noiselessly. 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 200mW into a 32Ω load at 1% distortion. This ensures both low and high impedance headphones are fully powered with optimal musicality. Dual AK4493SEQ D/A chips The left and right channels are each equipped with an efficient high-performance AK4493SEQ D/A chip. These 32-bit D/A chips support 768kHz PCM and DSD512, ideal for high-resolution audio source playback. RGB indicator lights 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. Worry-free listening Overheating, overload, and DC protection systems ensure that the K7 always operates at its best, so you can always enjoy a worry-free listening experience. Multiple independent power stages The K7 features a power design consisting of multiple independent stages, with the voltage of each stage regulated by low-noise LDOs. Feeding this power design is an external 12V switching power supply. All in all, the K7's power design supplies plentiful, clean power for an extraordinary listening experience. Smooth operator The K7 features an all-aluminum alloy construction, carefully finished with CNC and other processes. Its elegant black color is perfectly complemented by the gold accents of the THX and Hi-Res Audio badges and the splashes of color from the RGB lights. Precisely-tuned volume Thanks to its ADC curve reconstruction, the volume potentiometer features 112 smooth steps of adjustable volume free of channel imbalances and noise.
