Do different streamers really sound different when using an external DAC

Maybe this has been posted before but it seems that often when a post is made where someone has gotten better sound it’s because it was the streamer with included DAC that was changed, not just the streamer. No doubt a better internal DAC,  better file resolution, a better music service, will make a difference.

But I just want to see comparison of streamer to streamer with the same DAC implementation. I am currently using a Bluesound Node2i outputting via Coax into a high quality tube DAC
So here’s the million dollar question.

What have been your experiences in upgrading streamers, keeping everything else the same ie, DAC, cables, output type (Coax)? No doubt better control apps and having a display will elevate your experience but how about just sound quality. Anyone?

Thanks
