DAC with Headphone Amplifier

"Current Mode Amplification" Headpone Amp

CMA600i inherits Questyle Audio flagship headphones amplifier patent "Current Mode Amplication" technology, adopts all discrete circuit design, working in pure Class A status. Thus it can provide best sound required ultra-low distortion (0.00042%) and DC-600 (+0, -3dB) ultra-wide frequency. Plus the high quialty sound performance, CMA600i is capable to challenge world class Hi-end headphone amplifiers.

Full Balanced Output Design

CMA600i is equipped with 4-pin full balanced output, and dual 6.35mm standard headphone jack output. When the 4-pin full balanced output is working to drive a headphone, there are 4 groups of pure Class A amplification circuit output double voltage, and bringing quadruple power, so it can easily drive any high impedance headphones.

AKM AK4490 DAC Chip

CMA600i selects AKM AK4490 as DAC chip. Different from other DAC chip, CMA600i is specially designed with a +/-7V ultra high voltage power regulator to independently provide power for AK4490, ensure CMA600i with ultra large dynamics range.

CMA600i input supports PCM 44.1k-384k/1632bit signal, and True DSD64, DSD128, DSD256, DoP (DSD over PCM)64, DoP128 converting. It also supports 192k/24bit Optical and SPDIF inputs.

Patent "True DSD Converting"

CMA600i inherits Questyle patent "True DSD converting" technology. CMA600i drives program directly processes DSD source code for PC, and CMA600i hardware provides special DSD channel to process the signal strictly under SACD standard. As MAC OS doesn't support True DSD converting yet, CMA600i is also designed to convert DoP signal.
