Questyle CMA Fifteen Now Shipping in USA and Canada


Buffalo, NY, November 25, 2021—- Bluebird Music, distributor of high-performance audio products since 2000, is pleased to announce the availability of the Questyle CMA Fifteen, the latest evolution in Questyle’s ultra-high performance compact headphone amp/DACs. In addition to Questyle’s well-known proprietary technologies, the CMA Fifteen includes analog inputs, allowing it to serve as the preamp/DAC hub for a simple audio system of extraordinary performance and reasonable cost.

The CMA Fifteen commemorates 15 years of Questyle products utilizing Current Mode Amplification (CMA), and takes that technology one step further by directly coupling a Current Mode DAC with CMA. The output of most DAC chips is in current form, which is then amplified as voltage, following conversion by an intermediate stage. The M15 directly feeds the DAC’s current output into four balanced current mode amplification stages, eliminating unnecessary complication, and resulting in sound quality of unrivalled clarity and purity.

“Questyle products always offer incredible performance, terrific value, and unmatched build quality from Foxconn,” said Jay Rein, President of Bluebird Music. “One comment we frequently heard about the previous generation CMA Twelve was ‘I wish it had analog inputs, so it would be a full-function preamp’. The CMA Fifteen includes an analog input, and improves sound quality and functionality by directly feeding the DAC’s current output into the amplifier stages, and processing an even wider range of digital inputs. It’s an amazing product.”

The Questyle CMA Fifteen is in stock and now shipping in USA and Canada. US retail price is $2,495, ($3,095 Canadian).
