I contacted Oppo regarding MQA support for the Sonica and they told me the Sonica does not have enough processing power to do the full MQA decoding, which I find difficult to believe. They never answered my question about Roon support or the ability to choose digital filters, which you are able to do in the 205.
I am very disappointed in Oppo’s support for the Sonica DAC and told them so. They appear to be much more willing to add new features to their blu Ray players, while there hasn’ been a firmware update to th Sonica since May.
Write to them to express your feelings and what you want for the Sonica.
