Streamer suggestions with both wireless and wired connections

There are necessary components in our systems like speakers and amplifiers,  which are to be bought.  At the same time,  since one can  use a computer to stream 0s and 1s, is it justified to invert 5k or > on a streamer?

I am using a Blue sound Nide 2i streamer (not as a dac though) for already several years, sometimes I use my computer and actually I note no essential difference in sound quality. Some of you claim a night and day difference between SQ of different streamers. So I want to find out if I am really streaming constantly at night. I have no convenient Ethernet connection close to my audio system, besides would like to compare the defferences in SQ with wireless and wired connections.

Please help to create daylight in my streaming environment
