Channel Islands Audio (CIAudio) has released a USB to S/PDIF converter named the Transient MkII Asynchronous USB Converter.
The Transient MkII offers 24bit/192kHz data rates via an asynchronous USB link to source device – Mac or PC. The new Transient MkII is built around an XMOS based circuit that is claimed to have extremely low-jitter clocks.
Interestingly, the Transient MkII is also a DAC, with Wolfson DAC chips. A stereo RCA variable / fixed switchable output is provided, allowing the Transient to be used as a preamplifier to drive a power amplifier or powered speakers or more traditionally, as a DAC between a source component such as a computer and an integrated amplifier or preamplifier in a larger audio system.
For increased performance, the Transient MkII can be used with an optional separate power supply, the VDC-5 MkII, rather than via its USB hook-up.
