AURALiC SIRIUS G2.1 Upsampling Processor

The AURALiC SIRIUS G2.1 Upsampling Processor is a very special addition to the VEGA lineup and takes the performance of AURALiC's premium G Series DACs to another level. Through a Lightning Link connection this AURALiC Upsampling Processor ensures that all data streams from your AURALiC ARIES Streaming Transporter are Jitter-free converted to a DSD512 bit rate, allowing your AURALiC VEGA DAC to deliver the best possible sound quality.

This Upsampling Processor is also perfect for use with streamers and DACs from other manufacturers. To apply the AURALiC SIRIUS G2.1 in every imaginable configuration, it has both inputs and outputs for AES, COAX, Toslink and USB-audio. The general idea is that every DAC, cheap, premium, old and new, has a so-called sweet spot where it delivers the best possible sound quality. This is different for each brand, type and generation of DAC. But why is this so important?

The wide variety of digital formats

Most music enthusiasts built-up an extensive digital music collection with a wide variety of file formats and bit rates. This varies between a majority of 16-bit 44.1kHz files up to 24-bit 192kHz and sometimes even in DSD. Most of you will have noticed that not all resolutions are played in an equally good sound quality. AURALiC's technicians did also noticed this and for this reason they developed an Upsampling Processor with a dedicated DSD-upsampling algorithm to enable your DAC to perform the best possible way, regardless the bitrate of the original sound file.

High-quality build

This AURALiC SIRIUS is designed and built according to the same philosophy as the other AURALiC models. The signal processing is controlled by the AURALiC Proteus G2 system with a double Femto clock and is controlled by the AURALiC Tesla G1 platform. The DSD upsampling algorithm developed by AURALiC for this SIRIUS Upsampling Processor is most advanced and requires a high computing power. This is why AURALiC applied a specially developed FPGA solution for this purpose.

The SIRIUS is built with the same Unity Chassis II featuring a balanced weight distribution and a box-in-box construction to effectively shield the internal electronics against EMI/RFI. With this SIRIUS, the manufacturer uses its new damping feet that are equipped with a 6-way suspension system to effectively eliminate all resonances and vibrations. Finally, AURALiC applies its linear Triple-Channel Purer-Power power supply technology to provide an optimally galvanically separated power supply to all internal circuits.

The end result? With this SIRIUS Upsampling Processor the sound quality is stunning.
