Auralic SIRIUS G2.1 Upsampling Processor
Auralic VEGA G2.1 Streaming DAC
As a specialized enhancement product, SIRIUS G2.1 stands as the fourth addition to the award-winning G2.1 Series of AURALiC products. As a system, the G2.1 stack, comprised of ARIES G2.1, VEGA G2.1, LEO GX.1 and SIRIUS G2.1 now represent one of the most advanced digital sources available for your high-performance system today. SIRIUS G2.1 improves and optimizes signals from all sources, whether they are high-resolution files or streams from an inferior source or format. With SIRIUS G2.1, compressed, lossy, and poor recordings all have the potential to be improved, thereby upgrading your overall experience. Because SIRIUS G2.1 utilizes an open standard protocol, it can also be connected to any brand of DAC, delivering a global variety of sample rates and formats among other functions and features. SIRIUS G2.1 will provide universal balance to a world of varied formats, resolutions, DAC chip topologies, and algorithm types.

* SIRIUS G2.1 USB Audio input does not require driver for Mac OS X and Linux system. AURALiC USB Audio Driver is high recommended for use with Windows system. DSD512 is not supported by Mac OS X.
** USB DAC needs to be compatible with Linux system. DSD512 can only be output via native DSD format because the maximum DoP output rate is limited to DSD256. Please check with your DAC's compatibility.
*** All tests are processed under "Precise" filter mode.
**** All signals coming from any input will first be converted into a high frequency multi-bit data stream for jitter removal and for any user-enabled processing. The processed data will then be resampled to the customer’s selected output frequency and then be sent out of SIRIUS G2.1. This processing structure means SIRIUS G2.1 does not have a passthrough mode and will not passthrough MQA content.
