Hi Guys-- I believe if you look at the Pandora web sight you will find that it says that it will not put out 192K through these internet box devices. I have a roku also and love it. I use Pandora but MOG is the one I really love. I am not an expert and I may be wrong because I am going by memory only. I use an optical cable to my dac and it sounds good.
Hope that helps?
