New DAC or New Streamer or New Streamer/DAC

I am with  mtdining (6 posts above) I racked my brain out over this whole music server thing. Tried a few options both inexpensive and pricey. Ended up with a Roon Nucleus feeding my DAC direct via USB. I am not sure why you would need anything else? The Nucleus is a server, with the capability of adding a hard drive containing your own library. And if you don't mind paying for Roon's subscription, you can't get a better music manager.

Sorry acurus, but isn't a server and a streamer basically the same thing? A server serves stored music and a streamer streams music over the internet. I only mention Roon (which can stream as well) because it has such a user-friendly interface. It's about as good as it gets except for maybe Sonos.  If you like your existing DAC maybe just get something to feed it.
Also, just curious, what have you got against a USB outputs?

OK, so how are you connecting your steamer to you DAC? 

Inotherwords, Ethernet to streamer then what?
If the DAC and streamer is in one box I get it, but if you are using your Pass Labs DAC, how do you connect to that now, USB? Is that what you are trying to get away from? I'm still trying to wrap my head around all this stuff!

I'm missing something here. Is it not the DAC that dictates the end musical result?  How does one streamer sound better than another (without an onboard DAC)?
Similar to that of a CD player being used solely on its own, compared to being coupled to a DAC and used only as a transport.
