Something about " reclock " & "dejitter ", which I couldn't comprehend...

Hi y'all,

Firstly, sorry to bring out this old question again, but recently I just received this inquiry from my friend who is also on his way to digital streaming though, as we were discuss whether a network switch would help or not like everyone else, he sorta struck me with this, " Based on some researches, I found that most hi-end or high quality digital audio devices would reclock and dejitter signals on the arrival anyway, so what's the possible benefit of doing that in a network switch prior to arrival? "

I was speechless lol, because I didn't know about this, and I bough a network switch myself actually, so I seriously would like to prove my point to him!

If you guys have some insightful opinions regarding this question, please do share, I'm dying to learn...

Best,
