CMA Twelve, the new flagship DAC / Headphone Amp from Questyle, inherits their classic desktop design format and outperforms its peers once again. It marks the anniversary of Questyle’s revolutionary Current Mode Amplification technology, invented 12 years ago.
The elegant lines and laser etched text for status and volume echo the professional “genes” of the Questyle family. Serious thought for every detail is revealed with the amber glow of each LED indicator against the black or gold, sandblasted chassis.
Only when you see it will you truly understand the exquisite finish and design detail achieved between Questyle and their manufacturing partner, Foxconn, setting new benchmarks in technological standards. The chassis of the CMA Twelve has very high efficiency for heat dissipation, which ensures it will work with absolute stability in pure Class A, keeping the temperature at 45 degrees.
Mechanical vibration will affect audio signal processing and the resulting sound. To avoid resonance, the CMA Twelve chassis is formed from 10mm-thick aircraft-grade Aluminum 6063, with high precision machining techniques of ±0.02mm.
Questyle's patented Current Mode Amplification technology is set apart from other technologies adopted in traditional amplifiers. It will provide users with an experience of being there and listening to the original sound.
Questyle's pure Class A BIAS Control system can perfectly drive headphones or speakers of different specifications and easily bring their full abilities to fruition.
CMA Twelve is designed with Questyle patented True DSD technology and AKM AK4490 DAC chip. It processes DSD Signals without any PCM converting and provides True DSD.

CMA Twelve is designed with four groups of Current Mode amplifiers, exhibiting forceful driving power and an ultra-low distortion level of a mere 0.0005%. Plus the high-performance BIAS Control System, CMA Twelve will give full performance to your headphone or speaker systems and bring you an exceptional listening experience.
Balanced headphones with a 4.4mm connector are a rising trend with many headphone manufactures including Sennheiser, Audio Technica and Sony, launching products with 4.4mm-connections. CMA Twelve is Questyle’s first device to feature the 4.4mm jack and Questyle is committed to support this growing trend.

In addition to SPDIF and Optical inputs, the CMA Twelve supports a professional AES input and XLR output. Live recordings can be monitored in real time via the 6.35mm headphone output. Output level matching is user switchable between Studio and Standard mode. In the Studio mode, the power level will increase from 14dBu up to 20dBu instantly, matching it with studio-level professional equipment.
Digital audio signals from your PC, music server, CD or Blu-ray can be sent to the CMA Twelve via AES, SPDIF, Optical or USB. The core patented technologies of Current Mode Amplification, True DSD and 3x Clock Asynchronous Transmission allow the CMA Twelve to offer outstanding performance from its DAC and pre-amplifier. The specially designed ADJ/FIX switch is used to match with power amplifiers and active speakers.
There are two versions of CMA Twelve, the first is the CMA Twelve Standard, the other being the CMA Twelve Master. The CMA Twelve Master has a “MASTER” laser etching, and features a ROGERS Ceramic PCB to ensure the ultimate performance for sound quality and in specifications. The finish of both the CMA Twelve Standard and CMA Twelve Master are both available in your choice of Golden or Black.
Note: FIX/ADJ: Fixed Output Mode or Adjustable Output Mode of the pre-amp.
