Standard USB inputs on DACs are common. What isn’t common is what we do with ours. The entire USB module has a high level of isolation between the USB hardware and the DAC. The USB interface is limited to 384kHz and 4xDSD. Our MQA version also supports full MQA decoding.
Advantages:
-Synchronous to the DAC
-Works with most music server and computer systems that support USB audio
-Works at rates up to 24/384kHz and 4xDSD
Limitations:
-Limited level of isolation between the DAC and the often extremely noisy source
-Offers no software control of the DAC from the host source (Volume, etc…)
-Limited to short cable lengths
