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

Good question which brings up another question of what would be the price range for improvement.  So there are some in the 2-3k range such as Mytek, then there are as several in the 5-6k range such as PS Audio etc. all the way up to DCS with a Bartok at 15k to Vivaldi at over 100k . 
Cant afford the the Vivaldi :(  but don't want to spend 2 or 3k for a "lateral" move.  I would guess then that some those in the 5k plus region would ( or should ) provide a noticeable improvement in Sound quality as well as a stable and reliable source.  ( ie the DAC in my McIntosh C2500 often locks up when changing sample rates, hence my move back to the Oppo which is very stable and actually sounded better ) I would say the DCS Bartok would be to top of the budget would prefer something less expensive that would still be an improvement
