Not enough information about your LAN or streamer to give you a meaningful response. But at some point you have to convert fiber to copper and/or copper to fiber. And for that conversion, quality matters. As does the PSU for the converter/switch.
Does ethernet switch quality matter when using fiber connection?
From my understanding noise should be eliminated once it reaches the fiber cable since glass will carry the pure signal
With this in mind, should one disregard a more expensive switch such as ETHERRegen when streaming with fiber in favor of a > $100 switch.
Is it still worth investing in an audiophile grade switch and if so why?
