A World Class DAC section with True DSD
Unlike other DACs that claim DSD support, yet in actuality provide DoP (DSD over PCM), the CMA800i accepts the DSD bit-stream directly from your computer, bypassing your computer’s audio processing and digital volume control as well as the CMA800i’s digital filters, to provide True DSD, the way it was meant to be heard, without requiring expensive difficult to install proprietary connectors.
With DSD over PCM, the DoP breaks up the bit-stream into 16bit packets and compresses them into a PCM data-stream and then uncompresses them at the other end, buffering them, then reassembles into the bit-stream so that it may be sent to the DAC as DSD.
All of this requires an extreme amount of processing from the computer and the DAC performimg 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 CMA800i offers a more advanced IIR digital filter, which completely eliminates the pre-ring from the impulse wave producing a more natural sound.
Match the Questyle Audio CMA800i with Active Speakers
The Questyle Audio CMA800i is an excellent choice to drive active speakers.
Hi-End Components Throughout
Superior sound performance requires the use of Hi-end components. Questyle uses only the very best in the CMA800i, each component undergoes an extensive testing and selection process, many are custom made and purpose built.
10mm Thick Aluminum Cover and Bottom Chassis
The aluminum chassis is produced by Foxconn using precise CNC tooling machines. The upper cover and bottom chassis “mutual bit” structure design, provides stable heat, excellent control of sympathetic vibration and excellent shielding from RFI/EMI radiation.
Each product is burned in for 72 hours before shipping and every product has its own serial number and test report. The engineers prepare two copies of the test report, one report is put in the box for the customer and another report is kept in a safety deposit box at Questyle.
If there are any questions, about any product, at anytime, Questyle is able to find the report, for that unit, to aid in solving any issues.
