Streaming Audio Questions

I've recently started back into the whole stereo game after many years. I am interested in getting into streaming audio to my stereo and have questions I hope to get help with. Is it better to get a streaming system like the Bluesound Node going into my system or is a decent quality DAC from my laptop the way to go? I first heard a Sonos player through some darn good gear at a stereo shop and was underwhelmed with the sound quality. I read on the internet about the hi- res playback of the Bluesound and wonder if that is a good stand alone unit or if a DAC from my laptop would be as good or better than the Bluesound? Are there other hi-res streamers on the market? Is Tidal the only hi- res streaming site? Anyways, a bunch of noob questions I'm sure but I really need some guidance. Opinions would be appreciated.
