Questyle 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.
After 3 years of pre-research with ESS, Questyle selected the flagship DAC ES9038PRO, a decoding chip with the most powerful performance of any DAC invented to date, and jointly launched CMA Fifteen with ESS, supporting 32bit/768K and DSD 512 master band formats.
To chase extreme performance, almost all high-end DAC chips from world-renowned manufacturers feature current-type output, which in most traditional amplifiers, is then coupled with an IV converter and classical amplifier architecture. But Questyle wondered: if the DAC’s output is already current-type, why don’t we also amplify that signal in current-mode? And that’s exactly what they did in the CMA Fifteen: they use the ES9038PRO current-mode DAC, and couple that to four Current Mode Amplifiers, which together operate in fully balanced mode to achieve “system-level lossless” purity.
CMA Fifteen supports MQA full decoding
MQA is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is yet small enough to stream or download. The CMA Fifteen includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording.
CMA Fifteen supports LDAC Bluetooth
As a global member of Sony, we equipped the CMA Fifteen with LDAC Bluetooth. LDAC™ is a new audio technology from Sony that allows you to enjoy high quality wireless audio via Bluetooth. With 3x data transmission rates as compared to traditional Bluetooth, LDAC provides an enhanced wireless listening experience for all your music.
Bring Apple music lossless work to your high-end audio system
The CMA Fifteen supports Apple Music Lossless. In addition to the classic USB Type-B input, the CMA Fifteen now also features a USB Type-C input to solve the wire conversion loss through cables. You can finally enjoy the new experience of high resolution lossless audio online, anytime, anywhere. *USB Type-C input has priority. When USB Type-C and Type-B are connected at the same time, the system will process the Type-C audio source by default.
CMA Fifteen as a Preamp for your record player
CMA Fifteen now comes with analog inputs on the back of the unit. Connect CMA Fifteen to your record player as a preamp, you can enjoy the best possible sound quality. If you ever get tired of your digital music, the CMA Fifteen can now also take you back to the golden age of records.
Continuity and Inheritance
Questyle believes that the greatest products are born from the smallest details. The CMA Fifteen continues the classic design concept and perfect manufacturing technology of its previous lines of products, while further improving on all the details. Resonance, for example, is always a detail that could easily be ignored in the design process. However, mechanical vibration does indeed affect audio signal processing and the resulting sound. To avoid this resonance, the CMA Fifteen chassis is formed from 10mm-thick aircraft-grade Aluminum 6063, with precise machining tolerances of ±0.02mm.
In designing the CMA Fifteen, Questyle also analyzed the layout balance before and after the machine is connected to cables, to ensure that any inherent resonance is minimized. The CMA Fifteen also has a complete output protection function: if the device fails for any reason or detects other abnormalities, it will automatically cut off the output to protect your headphones and stereo system.
