Moving up from an Oppo 205

I have an Oppo 205 that I am using as a DAC with an Aurrender N100 via USB.  It sound surprising good and actually a better sounding (and functioning DAC) than the one in My McIntosh C2500.  I not only listen to my collection of Hi-Rez files but also now Tidal with MQA.   What would be a noticeable upgrade for a DAC and or DAC with steaming abilities. 
Only from a 2ch audio perspective.  
Thank you
