Point of diminishing returns for a Network Streamers?

I run an Intel NUC as a Roon Core, streaming Qobuz (previously Tidal).  It's Linux based and does one thing with all that power--run the Core.  There's no other software on it.  Linux and Roon. That's it.  

When you use a laptop or personal computer, the unit has many other processes going on given all of the complexity in software these days.  Having a dedicated streamer to feed a DAC that doesn't run other stuff should cut down on noise. 

If I didn't use the NUC I'd use the ifi Zen or Roon Nucleus. 

I suggest and use a Bricasti M5 Network streamer. Really nice product and sound is excellent.  It has high quality build including LPS.  I experienced a significant sound improvement over using my Macbook connected to my DAC.  Since M5 is a NAS you can continue using your MAC as long as it’s connected to the same network by ethernet cable. I switched from my macbook to a PC laptop since PC can connect wirelessly. It works with Roon without issue.  I recently bought mine used $1400 but is easily worth msrp.  

Out with the ifi zen, in with the new bluesound NODE since it is supposedly a shoe-in fit with android. Just ordered it! And the journey goes on.

@larry5729 I had the Node 2 for a year it was great although the internal Dac was fair compared to my Pro-Ject Pre Box s2 digital dac. As a streamer, I would probably still be using it, however, it does not pass thru DSD file without conversion. I have my entire SACD collection ripped to my server. 

@gerrie I too like the Lindemann products. I recently bought a Limetree Bridge 2, and it has worked flawlessly since day one, and sounds very good running into my LinnenberG Telemann DAC-Pre. 

The nice thing too, looking ahead at where my system may be located, using wireless, the Limetree in my testing has worked better and more stable than my three times more expensive Naim ND5XS2. As far as sound, well, it is a lot closer to my ears than one might think, and I do really love the Naim streamer.
