Why do I need a switch?

Over the last years also tried Fiber conversation with standard FMC as well as with EtherRegen and very new Sonore OM Deluxe V2 with Finisar SFPs and Farad Super3 with SR Purple fuse, Furutech inlet and a AQ Monsoon power cord, all devices connected to a Audioquest Niagara 5000. All Ethernet cabling is with AQ Diamond.

It definitely reduces noise and makes things more calm, darker/quiet background etc. 

Though when using the Network Acoustics Muon Pro things were even more organic and intense / emotional. 

Hm, so I guess clocking would be another step up - but instead of getting an external clock for the EtherRegen I would like to get a better switch with a high end clock build in which should be even more effective.

if you get any recommendations I am glad to hear  

@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.

There is another highlight coming up from Network Acoustics, the just released new Tempus switch with own power supply: https://www.networkacoustics.com/shop/tempus-ethernet-switch/
 

Very much looking forward how this improves things! Will report here when I get it.
