are NET Switches worth considering?

Only possible reason to do it is if your existing streamer and dac are not filtering out noise coming from your ethernet connection.  The current Stereophile (Brilliant Corners column) has a brief mention of an extremely cost effective solution: TP-Link MC220L ethernet to fiber converters, TP-Link TL-FM311 SFP modules, and a short run of fiber optic cable.  

Another option, a little more expensive, is to just get same basic setup through Small Green Computer:

Systemoptique

Adding a NA Tempus was very positive for my Innous Statement so yes it is worth considering a switch.  The Tempus replaced 3 switches I used to isolate my audio gear from the home network.

Now I feed the Tempus with a Sonore/SGC Systemoptique OpticalModule Deluxe with the upgrade Finisar SFP's.  Previously the Systemoptique was used between two of the switches.

I also added the Muon Pro Streaming System from NA.  Good thing about NA is the 60 day trial.

In my experience Audio switches are definitely beneficial, some more than others.

@rikkipuu sounds complicating and above my audio comprehensive skill set lol. You obviously have knowledge and experience in this area.  What about a simple unit like the Innuos PhoenixNET?

Hello @fire_water ,

@ddgtt  but the " self-proclaimed experts" will tell you otherwise. 

in response to @ddgtt  saying

A good audiophile grade ethernet switch makes a significant and important difference. 

I don't think so.  'self proclaimed experts' or actually many with true experiences with less expensive switches will state that what they have is fine, and that you do not need a more expensive switch, and that (without hearing one) they are not an improvement over what they have.

I and many have journeyed through lesser switches and can state without hesitation that a quality audiophile switch like the GTT DeJitterit, Network Acoustics Tempus, or Telegartner (JCAT M12) make a huge difference at a certain level.  And the power supply (included with the first two switches, and recommended for the third, make an equally stunning improvement.  No one has to believe this, but I do.  Now are there newer value switches that sound as good?  Possibly, but not the aforementioned English Electric, Bonn 8, etherRegen and others.  This is based on my trying them, hoping to not spend more, and then trying a better one and clearly hearing the difference.  Now the Phoenix Net?  I have not heard it.  I see the attraction being matchy to your streamer.  But I have not read here that it compares favorably to the three I mentioned.  Please no stone throwing from network engineers...only reporting my findings and what I hear.

OP - seems like the best choice is to try a used PhoenixNet for yourself then sell if dissatisfied.
