XI AUDIO SagraDAC 2 Product Background

The name "SagraDAC" is derived from the Sagrada Família in Barcelona, Spain.

When Michel Xiao, the chief designer of XI AUDIO, first laid eyes on the Sagrada Família, he was so deeply moved that he sat down on the ground and vowed to create a product that could evoke a similar sense of awe. The R-2R DAC SagraDAC is the result, designed to deliver the utmost musical inspiration.

SagraDAC 2 has added digital volume control and a remote control on the basis of SagraDAC, aiming to provide customers with more functional applications. The sound performance of SagraDAC is identical to that of Sagara DAC 2.

SagraDAC 2 is equipped with custom-made R-2R modules from Soekris, a custom USB interface board from Amanero, XI AUDIO's own custom transformers, discrete power circuits, and more. Every detail, from digital to analog, has been meticulously crafted to achieve the highest audio quality.

At the heart of the DAC lies the cutting-edge Discrete R-2R Sign-Magnitude Technology. It employs a programmable large-scale logic chip for all digital processing and uses a multitude of highly accurate thin-film resistors for D/A conversion. While this R-2R algorithm was once dominant, it lost out to cost competition in delta-sigma DACs and is now only employed in select high-end models.

Leveraging the advantages of lower costs for programmable digital logic chips and the availability of highly accurate thin-film resistors at a lower cost, along with the use of boards manufactured using state-of-the-art surface-mount technology, we have developed our unique R-2R technology to offer exceptional performance at a reasonable price.

Experience the revival of R-2R DAC in the modern era and enjoy the music through SagraDAC 2.
