An outstanding all-in-one device should be no-compromise

The Questyle Audio CMA800i headphone amplifier section follows Questyle’s patented "Current Mode Amplification" design used in their flagship headphone amplifier, the Questyle Audio CMA800R, in fact , most of the components used are the same. The ultra low 0.00026% distortion, ultra wide bandwidth, up to 850kHz (+0, -3dB), and Super-current pure Class A architecture enables the Questyle Audio CMA800i’s amplification to be unparalleled among all-in-one DAC/amplifier models.

A world class DAC section with True DSD

Unlike other DACs that claim DSD support, yet in actuality provide DoP (DSD over PCM), the Questyle Audio CMA800i 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 CMA800i’s digital filters, to provide True DSD, the way it was meant to be heard.

The Questyle Audio CMA800i achieves this without requiring expensive, difficult to install, proprietary connectors, or as is the case with DoP, breaking up the bit-stream into 16bit packets and compressing them into a PCM data-stream and then uncompressing them at the other end, buffering them, then reassembling the bit-stream so that it may be sent to the DAC as DSD. All of this requires an extreme amount of processing, at both the computer end and the DAC end, to perform in real time (which invariably leads to latency, data loss, etc), not to mention a 33% increase in bandwidth requirements for the USB ports and cabling.

IIR Digital Filter

Currently the majority of DACs use FIR (finite impulse response) digital filters, but research and testing has shown that our ears are very sensitive to the pre-ring that FIR digital filters add to the impulse wave, making the music sound incoherent and unnatural. The Questyle Audio CMA800i offers the more advanced IIR digital filter, which completely eliminates the pre-ring from the impulse wave producing a more natural sound.

A separate pre-amplifier section

The Pre-Amplifier output is another unique feature of the Questyle Audio CMA800i. 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 CMA800i is designed with a totally independent pre-amplifier, even the power supply supporting the pre-amplifier circuit is independently located.

In keeping with Questyle Audio’s no-compromise approach and to make usage more convenient, an analogue volume control circuit is employed, using an ALPS27 motor controlled potentiometer for operation via remote control.

Wolfson Flagship Chip WM8741

The sound of WM8741 can be described as classic "English"-style, delivering a soft and exquisite sound. Due to Questyle's high requirements for D/A design, LPF is discarded (per Wolfson ’s suggestion) in the Questyle developed analogue output circuit for the WM8741, receiving official praise from Wolfson.

10mm Thick Aluminium cover and bottom chassis

The Questyle Audio CMA800i’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 CMA800i with stable heat, excellent control of sympathetic vibration and excellent shielding from RFI/EMI radiation.
