The CMA600i is an advancement of the CMA800i. This all-in-one DAC and Current Mode headphone amplifier and pre-amp inherit the patented current mode topology of the original Questyle CMA800 amplifier. The CMA800 propelled Questyle Audio globally as it was the first Current Mode amplifier to be manufactured with brilliant and stable performance.

Design

The Questyle Audio CMA600i Integrated Desktop DAC with Headphone Amplifier uses a USB port that works well with a unique 3X Clock structure, this guarantees a sync with the finest AK4490 32-bit DAC chipset by AKM. The chipset contains a recently developed switch capacitor filter “OSR Doubler” which helps in dropping sound degradation from noise shaping to attain a flat noise floor up to 200kHz. The AK4490 chipset gains optimal sound performance by reducing jitter and pre-ringing to untraceable levels. The CMA600i also exhibits a 4-pin balanced XLR stereo headphone output. It is also equipped with XLR and RCA pre-amplifier outputs, supporting 24bit/192KHz transmission to a discrete power amplifier.
