Questyle - CMA Eighteen Master

Flagship Desktop DAC/Amps (The Pursuit of Excellence in an Upgraded Flagship)

As the flagship DAC/amp of its time, the CMA Fifteen was almost perfect in 2020. The question then arose, how to improve it further? After much exploration and research into superior designs, the result is Questyle's latest flagship, the CMA Eighteen Master.

Current Mode Amplification

Current Mode Amplification , referring to a Current Mode Audio Amplifier, is a patented technology of Questyle Audio. It is a state-of-the-art technology of audio amplification different from the traditional audio amplifier. As the “engine” of audio system, Current Mode Amplification,driving headphones or speakers work and has a great impact on the hearing experience.

CMA Eighteen Master chose the latest flagship DAC ES9039Pro released by ESS, which has the highest performance of the global mass production DAC. ES9039Pro has 8 independent DAC cores. When applying on the CMA Eighteen Master, we will connect each 4 kernels to build a powerful stereo DAC link.
