Technology
Current Mode Amplifier
CMA400i is built with four groups of pure Class A Current Mode Amplifiers and all discrete circuit, which achieves the ultra-low distortion level of 0.0006% and ultra-wide bandwidth up to DC-600kHz(+0,-3dB). The impressive technical performance together with warm and powerful sound makes CMA400i comparable with a high-end headphone amplifier.
Full-balanced Amplification
CMA400i can drive headphones in full-balanced mode as it features four groups of pure Class A Current Mode Amplification circuits, and supports a 4-PIN balanced XLR output, a 2.5mm balanced headphone jack and a 6.35mm standard headphone jack. In addition, the new design of Gain Control switch at the bottom of the chassis benefits CMA400i with perfect driving power for different headphones.
Direct Stream Digital
PCM384 | DSD256 | 32Bit
CMA400i is designed with Questyle patentedTrue DSD technology and AKM AK4490 DAC chip. It processes DSD signals without any PCM converting and provides True DSD.

CMA400i’s chassis is made of aircraft-grade Aluminum 6063 and manufactured by Foxconn. The “mutual-bit” structure and 10mm thick chassis with the CNC-tooled aluminum feet help to reduce the natural resonance to the lowest level and make CMA400i strong and stable as well.
System
Build a PC High-end System
CMA400i has a great capability for signal processing, supporting Win XP, Vista, Win7, Win8, Win10 and Mac OS. When connecting to a computer, it is only responsible for sending data. So, everything related to sound quality will be guaranteed by CMA400i, no matter it is a song, a film or a game.
Match CMA400i with Traditional Digital Sources and Active Speakers
The performance of a traditional Hi-Fi system can be much improved by CMA400i because of its completely separate DAC with optical and coaxial interfaces. Another distinctive feature of CMA400i is switching between “Headphone Amplifier” and “Pre-amplifier” by the “Function” switch on the front panel. In DAC mode, CMA400i supports RCA and XLR pre-amp outputs which can be selected by the ADJ/FIX switch on the rear panel.
