CMA600 is a modularized Current Mode Headphone Amplifier. Different headphone provides different sound style, while requires different amplifier to drive with. CMA600 is designed with M1, M2, M3 three different style modules, separately to drive different brand or different impedance headphone to enable their best sound performance. The modules are easy replaceable, just remove the upper chassis then it can be easily discharged.

These three modules are all applied with Questyle patent Current Mode amplification technology. Even though they use different circuit design and different materials, they all provide most approach to physical limit capacity: less than 0.0005% ultra-low distortion, more than 500KHz broad frequency response, up to 120dB SN ratio. Fast speed and low distortion, CMA600 perfectly express the dynamic and transparency of music, precisely discover the deep hidden details.
