There are many renderer interfaces in the industry. We designed and developed our own processing card and software with performance and low noise in mind. Our Renderer V2 interface is MQA and Roon Ready and has a maximum sample rate of 32/768kHz and 4xDSD. The entire renderer solution is galvanically isolated from the DAC, including isolated power. The main advantage of the Renderer Input module is that it turns the DAC into a network endpoint for many current playback software packages and allows computer control of the DAC volume.
Advantages:
-Synchronous to the DAC
-Offers software control of the DAC from the host source (Volume, etc…)
-Works at rates up to 32/768kHz and 4xDSD
-MQA decoding
-Roon endpoint
-Lower noise than most music servers or direct USB connections
Limitations:
-Only provides a medium level of isolation between the DAC and the typically noisy home network
-Prone to network issues
