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.

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.

Since the first Questyle Audio CMA800 was born in 2007, the current Questyle Audio CMA800R is product of 22 editions and continuous testing to improve and update.
