The Questyle Audio CMA800R, the flagship Current Mode Headphone Amplifier from Questyle Audio, is a milestone of headphone amplifier design. The CMA800R implements Questyle Audio’s outstanding Current Mode Amplification™ technology, providing an ultra-low 0.00038% distortion, a wide bandwidth of 650KHz, and an 114dB Signal to Noise Ratio. These parameters are far beyond what any other existing headphone amplifiers can achieve. 

Beyond that, the Questyle Audio CMA800R is the world's first headphone amplifier to support Mono Full Balanced operation (a bridged mono configuration for use in a dual mono application using 2 Questyle Audio CMA800R amplifiers). In full balanced mode, its distortion is further reduced to less than 0.00026%.
