Why do I need a switch?

@ghdprentice As a streamer I am using a LUMIN U2 Mini which is tuned with a Farad Super3 (purple fuse & furutech inlet with a AQ Dragon power cord) instead of the standard SMPS. The amplifier / DAC is a Devialet 440 Pro.
Between the LUMIN and the Etherregen there is the new Network Acoustics MUON Pro streaming system which is an additional improvement.
Having a system which is highly resolving I hear every slight change - so very much looking forward what area to address that will gain another uptick in sound quality.

A cheap addition would be a PinkFaun Isolator going into the Devialet. You might be pleasantly surprised. Also adding a quality clock to the Etherregen and more importantly a better power supply has major benefits

What just happened to my system?  I am a newbie to two-channel network switches.  I started researching them a month ago.  I thought my music sounded fantastic, to begin with.  I purchased a TeddyPardo LPS for the very front end of my whole house network to run my Netgear Modem.  Then I researched Switches.  I have an Araknis 310 and 210 Switch and Router for my whole house but nothing for my two-channel.  

I had a long conversation with Rob at Network Acoustics and I decided to buy the Muon Pro Cabling system with filter.  He also suggested I try a cheap Dlink switch in between my Cat6 and the server.  I could not understand what the switch or the Muon Pro series would do for my system.  That is why he suggested I try a cheap switch before investing more money in an expensive switch.  I should say that Network Acoustics also has a 30-day money-back guarantee.

I have a relatively high-end system.  I could not believe the results I got when I added the $37 switch and the Muon Pro cables.  I am befuddled.  Wow!  My music has never ever sounded better.  

I am getting an upgraded Lucas Audio LDMS Music Server early next week.  Lucas Domansky is the designer and developer of the LDMS.  I currently have one and his Music Server is top-notch.  When he sends me the new one, he will include a new network switch that he says will blow my mind.  He also wants me to move my TeddyPardo to the switch he is sending me.  If my musical experience gets any better I might have to cancel the Aries Cerat equipment that I have on order.  I can't wait to get the new server and switch!

I'm not sure about the NETGEAR GS108Ev3, but I have the similar TP-LINK TL-SG108. Replacing the nasty wall power pack with a decent, ripple free power supply has made a huge improvement to streaming SQ.
