"Conclusions
SMSL cuts the functionality to minimum many need to have high quality conversion of digital to analog from multiple inputs. Performance is superb for the cost as it provides full transparency to the source. It proves that performance requires great engineering skill, and not a ton of money. A lesson that I hope one day high-end audio companies and their customers appreciate.
I am happy to recommend the SMSL SU-1. There is no more excuse for having bad DAC performance!"
Balanced output?
