What is it?

CMA600i follows the design of Questyle Audio’s flagship current mode DAC with
headphone amplifier CMA800i and uses components of the same level. The
headphone amplification of CMA600i produces ultra-low distortion to 0.00042%
and ultra-wide bandwidth up to DC-600kHz (+0, -3dB), working under super-
current and Class A state only, all of which makes CMA600i most outstanding at
headphone amplification among the all-in-one models.

CMA600i’s USB input supports True DSD. Different from the commonly used DoP
mode, CMA600i processes source data directly from PC and its hardware will
switch to the True DSD channel when the system processes signals, strictly
following the process of SACD playback.

CMA600i supports pre-amp unbalanced (RCA) and balanced (XLR) outputs. RCA pre-
amp output level is up to 4Vrms, and XLR up to 8Vrms, which can meet the
requirements of most power amplifiers for output level… Volume control employs
an ALPS16 potentiometer working in analog mode only, supporting remote
control. It is user-friendly for users of high-end active speakers.

CMA600i supports headphone balanced output, four groups of pure Class A
current mode amplification circuits drive headphones in full balanced mode,
doubling the output voltage, quadrupling the output power against that of
single ended mode. It can easily drive headphones of low impedance and high
sensitivity rating, able to reveal full performance of your headphones.

Performance of the circuit will be improved by Hi-end components. The sound
quality and durability of CMA600i is guaranteed by us
