Current-mode audio amplifiers affect the speed and bandwidth of the transistor-level capacitance between the low impedance nodes, not only completely eliminate the transient intermodulation distortion (TIMD), but can easily attain ultra-high bandwidth (full power bandwidth of 500kHz ) and ultra-low distortion (lower than 0.0002% , challenging the physical limits of audio testing).
The CMA800R Current Mode Amplification section is of a fully discrete design and all transistors work in pure Class A. The Questyle Audio CMA800R headphone amplifier Patented Current Mode Amplification technology brings CMA800R excellent performance. 0.00038% ultra-low distortion, challenges the physical limit of audio testing.
Ultra-wide bandwidth of 650kHz, is 32 times beyond human hearing.
