What is it?

The quest is over! The Questyle Audio CAS192D, the first DAC equal to the
performance of Questyle’s Current Mode Amplification, is now the world’s first
DAC to support True DSD.

Unlike other DACs that claim DSD support, yet in actuality provide DoP (DSD
over PCM), the Questyle Audio CAS192D 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 CAS192D’s digital filters, to provide
True DSD, the way it was meant to be heard, 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
which 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.

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 CAS192D offers the
more advanced IIR digital filter, which completely eliminates the pre-ring
from the impulse wave producing a more natural sound.
