We’ve blown more than a few column inches on AURALiC’s G2 system, and for good reason; the ARIES G2 Wireless Streaming Transporter, VEGA G2 Streaming DAC and LEO GX Master Reference Clock work together to deliver one of the finest streamed digital sounds you can get, irrespective of price. The system is completed, however, in the AURALiC SIRIUS G2 Universal Upsampling Processor.
The nature of the SIRIUS G2 does create a bit of a conundrum for the reviewer. Do you review it as the last part in the big AURALiC jigsaw, as a standalone upsampler for equally high-grade systems, or both in and out of AURALiC’s matching products? I went predominantly for context rather than comparison, but in reality, what applies in the AURALiC stack holds equally well elsewhere. So, it sits in the now four-tier stack of AURALiC – with the ARIES G2 at the head of the table, the VEGA G2 connecting the whole caboodle to the next device in the chain, and the LEO GX and now the SIRIUS G2 making each component give its best possible performance in that system.
Of course, this means a lot of potential ways to configure the system, as you will be looking at something like an Ethernet connection on every box, and inputs like coax or USB on three out of the four boxes. Which goes where for the best sound? The reality is there is a lot of redundancy or upgradability (depending on viewpoint) here. Taking the slow route to full AURALiCOSITY, you will likely start with the VEGA G2 DAC, amassing all your source components to play them through that device on its own. From here, most will likely go with the ARIES G2. This Streaming Transporter acts as a bridge product, collecting all the digital inputs in one dedicated place and controlled by the Lightning DS app. Just one Lightning Link cable connects all those sources to the DAC, and instead of taking some kind of proprietary route to create this high-speed digital connection, the company uses HDMI connectors (even if the connection itself is not run as part of the HDMI protocols). This makes adding in the additional products a breeze; the next in line is the SIRIUS G2 tested here, which requires a single Lightning DS connection to hook all three devices together, and then the LEO GX requires three cables to link all four devices together.
