Roon's update sounds really good

Hello, 
I thought it was better to use WiFi so you cut down on noise and grounding issues. The router is connected to your ISP. Doesn’t that mean you grab garbage from them?  Or is there a filter for that?  Please do not comment rudely to this post. I really do not know. 

Hello, 
does the buffering take care of the interruptions like matching the clocks?

The modem connects you to the ISP, you can have a modem/ router combo, not sure what you mean by grab garbage from them? 

Hi @hshifi
So,  all internet traffic happens using TCP/IP. This protocol has source and destination IP addresses.  The only traffic coming to your router is traffic specifically sent to you.

Some of this traffic is of course malicious and intended to look for vulnerable services. The router behind the modem is responsible for blocking all incoming traffic that is unsolicited/unwanted.

Having said this, I have seen coaxial cables cause ground loops.  Having a cable isolator fixes these.

Best,

Yes.  Ideally, you have more data than is asked for.  Say 1 seconds worth.  While the input/output must be balanced, on average, it does not have to be exactly right all the time.  So, the DAC may continue to feed off the buffer even if the incoming data is randomly delayed by 0.01 or more seconds.
