■Powerful driving performance of desktop class

- By enabling the newly installed "desktop mode", the balanced output achieves the highest output in its class of 560mW (doubled from KA5). From low impedance to high impedance, it powerfully drives all headphones, allowing you to experience authentic sound that combines power and delicacy.

■Advanced sound quality adjustment function "Lossless PEQ"

- The newly installed **10-band high-precision lossless PEQ (parametric EQ)** allows you to finely adjust the sound quality to your liking. You can simulate and correct the frequency characteristics of your headphones using a dedicated app or on the web, allowing you to enjoy high-quality sound making without worrying about sound quality degradation.

■Top quality parts and high resolution support
- Equipped with a dual high-performance DAC chip "Cirrus Logic CS43198" and an op amp "SGMICRO SGM8262". This luxurious combination achieves outstanding sound quality performance despite the small body. It supports playback of high-resolution sound sources up to 768kHz/32bit PCM and DSD256, and has also obtained Hi-Res Audio certification.

■Smart power saving and various functions
- Equipped with an innovative real-time current and voltage monitoring function, it achieves high-quality sound playback while reducing the power consumption of your smartphone. It is also extremely easy to use with two intuitive volume adjustment modes (60 levels / 120 levels) and customizable A/B button operation. The 0.96-inch IPS color LCD screen displays a playful animation of an analog cassette tape spinning during operation, making it visually enjoyable.

■Excellent compatibility and expandability
- USB Type-C connection supports a wide range of OS including Android, iOS, iPadOS, Windows, and macOS. If you select UAC1.0 mode, you can also connect to many devices such as the latest game consoles. In addition, the 3.5mm jack also functions as a coaxial digital output and can be linked with an external DAC. It also supports CTIA standard microphone input and has a strap hole, making it highly expandable and convenient.
