CMA600i Balanced Headphone Amplifier and DAC

The Questyle Audio CMA600i headphone amplifier section follows Questyle’s patented "Current Mode Amplification" design used in their flagship headphone amplifier, the Questyle Audio CMA800R. This model has impressively low 0.00034% distortion, with up to 950mW on tap, for low impedance headphones. The CMA600i doesn’t shy away from the heaviest loads either, with a 4-pin balanced XLR connection to maximise sound quality.

The entry level CMA600i utilises a USB port that adopts a unique 3X Clock structure. This ensures a proper sync with the premium AK4490 32-bit DAC chipset from AKM. The chipset includes a newly developed switch capacitor filter "OSR Doubler" that greatly reduces sound degradation from noise shaping, achieving a flat noise floor up to 200kHz! The AK4490 chip obtains first class sound performance by also reducing jitter and pre-ringing to undetectable levels.

A premium DAC section with True DSD

Unlike other DACs that claim DSD support, yet in actuality provide DoP (DSD over PCM), the Questyle Audio CMA600i accepts the DSD bit-stream directly from your computer, bypassing your computer’s audio processing and digital volume control as well as the Questyle Audio CMA600i’s digital filters, to provide True DSD, the way it was meant to be heard.

Support for the highest quality formats

The Questyle CMA600i is designed to grow with your music collection. As well as supporting standard digital files via USB, toslink or coaxial SPDIF connection the CMA600i is also fully compliant with files up to DSD256 and PCM 384k/32bit over USB.

A separate pre-amplifier section

The Pre-Amplifier output is another shared feature of the Questyle Audio CMA800i and CMA600i. Many manufacturers, when designing an all-in-one model, use the headphone amplifier circuit loop to support the pre-amplifier output to reduce costs. To achieve the best possible sound performance, the Questyle Audio CMA600i is designed with a totally independent pre-amplifier.

10mm Thick Aluminium cover and bottom chassis

The Questyle Audio CMA600i’s aluminium chassis is produced by Foxconn, using precise CNC tooling machines. The upper cover and bottom chassis “mutual bit” structural design, provides the Questyle Audio CMA600i with stable heat, excellent control of sympathetic vibration and excellent shielding from RFI/EMI radiation. 330mm(W)x300m(H)x55mm(L)
