Questyle CMA Fifteen, Desktop DAC & Headphone Amplifier: Flagship DAC/AMP (CMA Fifteen)
The CMA Fifteen
Commemorating the 15th anniversary of Questyle’s revolutionary Current Mode Amplification Technology.
At its core, Current Mode Amplification uses current, instead of voltage, to amplify audio signals. It is a state-of-the-art technology in audio amplification, leading to tremendous performance differences when compared to traditional audio amplifiers. As the “engine” of the audio system, Current Mode Amplification features a fully discrete and topological structure, and can achieve ultra-high sound performance that reproduces music so faithfully, it feels like you are in the original recording room. Using Current Mode Amplification technology, listeners can attain a much better listening experience, even when using consumer-grade headphones and speaker systems.
