This is an excellent product, tested with Tidal MQA up to 192/24 only. I used the included USB to connect to a late 2013 iMac, used cell phone charger for external power, and then optical 25') to my DAC. I have 4 different DAC's and two HiFi Rose RS250 streamers with a good built in DAC. My familiar MQA tracks sound really good, I think better than any other combo I have tried. I am using my second best DAC, retail about $1250. I was skeptical a $60 product would be anywhere this good and am very happy. Recommended!
