Point of diminishing returns for a Network Streamers?

All a streamer really needs to do is transmit the bits from local storage or a music service to your DAC intact. It sounds as if your setup already does this. There’s no need to make a change unless you’re detecting noise / pops / ticks / dropouts during playback.

Why? Educated audiophiles can make better choices on what to spend their hard earned money on - whether that information is objective or subjective. I just happen to like to weight my purchasing decisions more towards facts than opinions.

In any case, I really don't care if someone wants to buy or recommend something if it sounds better to them. I'm just trying to point to actual audible phenomena vis-a-vis typical audiophile claims.

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.
