Ethernet switch worthwhile?


Is anyone using an audiophile ethernet switch for streaming as is it worth it? Recently was recommended using Uptone Audio EtherRegen switch to remove noise and jitter from the ethernet cable before it enters my Aurender N10 streamer. Or does the N10 also remove the same once it enters its own ethernet connection?  Also read Synergistic Research ethernet switch is very good. Thoughts?

I added a LHY-SW8 to remove any switching power supplies from my system.  It may have had a small impact on the noise level, but nothing major to my ears.  I did not do much testing at the time.    

As to comments about " testing" and "measurable" , we all know or should know sound related to music is not just numbers. You can take one preamp or amp and compare measurements compared to similar and one will sound way better than the other. Measurements cannot always define actual sound characteristics.  One may be dry and overly analytical and one may be warm and musical and sound more natural.  Just my thoughts on forums I see on here regarding this hobby and passion. 

Regarding the iFi LAN iPurifier Pro, in my case it was an inexpensive minor improvement using an Aurender N150, and not effective using an Innuos Pulsar.  To make things even more confusing there was no improvement at all until I got the upgraded iPOWER  power supply.  So kinda like what I said before. Too Many Variable’s. You won’t know til you try.
