Looking for significant upgrade from Oppo 105 to stream Tidal.

I am currently streaming Tidal through an Oppo 105D and am looking for a significant audible upgrade in the streamer and the DAC.  Oppo's Media Control ap has always been problematic so I will not miss that!  I don't like chasing reviews due to advertising bias. I do want to hear other people's real world experiences.  I am not sure if I want the streamer separate from the DAC, however, I want to be able to upgrade the DAC with future technological advancements if possible. Thanks to all responses in advance,
