Higher End DACs

Servers do heavy lifting in heavy lifting environments, streaming music files is not one of them unless you're Tidal or Qobuz. You’re better off keeping the server side completely away from the audio components connecting to a good streamer DAC like some mentioned here. Good DAC’s today filter noise and distortion and reclock the stream from the internal embedded clock as long as you’re not feeding it a garbage signal, use a decent NAS or server on a good strong network there’s no need to go bonkers price wise with the server side.

your thinking is about 3 years behind the current bleeding edge.

which is perfectly fine if you are happy. if you are wanting the best possible digital music reproduction you have some work to do.

@mikelavigne, I do not understand your above post.  As you posted, if "your thinking is about 3 years behind the current bleeding edge.", what are you recommending?    Please update the post with more details.  Thanks..

The OP was asking about DAC's and streamers not an over built boat anchor computer running some modified windows OS. Anyone who thinks tossing a server computer in their audio rack is about 5 years behind stick the thing in another room. The only thing I can find on this thing is a bunch of fan boys gushing over how neat it looks inside and sounds better than anything at any price without any sort of objective testing or measurements and a few units have been sold in a poor country so it must be good. I am sure this is probably  one of the best, quietest servers out there, it should be it's  built  like you're  using it to launch a rocket to Mars. If the OP wants a 100 lbs boat anchor than I say go for it if he wants an actual streamer and DAC I would look elsewhere.  There have been some pretty good possibilities mentioned so far. 

I don’t have $30k to blow on the Extreme, but my curiosity was piqued when romaz jumped on the Extreme bandwagon saying that it’s better than anything he could possibly build. Now I want to hear it to see what it’s all about. 
After comparing side by side the different Innuos models, and comparing it to my ultrarendu and optical rendu, I suspect the server/renderer have more impact on sound signature than the DAC.
