Joseph audio had the best streaming and all that was used was an older Apple TV box which had an optical connection that was connected to a streamer that impressed many with great sound from a YouTube video. YouTube video Quality is outstanding through a decent home theater system these days.
I've been streaming audio via youtube to my system for quite a while now. So if I'm on the sofa watching a youtube music performance on my phone, or ipad, I stream it to my Bluesound Node, to my 2 channel system.
The sound quality can be absolutely remarkable for many performances. One vulfpeck concert was "you are there" quality, same with many of the tiny desk concerts.
