Ethernet

@fastfreight I agree that front end tweaks and power cords can make a difference.  My thesis is that through engineering they should not!  Off the shelf components would appear to be available to solve the problems.

I agree with what you posted.   One point -- depending on the design of the streamer, it "may" help sound quality to "turn off" the wifi reciever on the streamer and use an ethernet cable.  

When I first got my N130, I tried the same thing.  I bought a long Cat8 Amazon cable. Yes it works, but the cable doesn’t have a lot of insulation and occasionally picked up noise.  I ended up buying a Netgear Powerline 2000 +extra outlet on Amazon.  Used it for years.

Yes ,but several factors , go to blue jeans cable and buy Beldons best Ethernet cable ,your rougher needs to have a LPS power supply ,that $5 wall wart just ads noise , then you need a decent quality Ethernet hub  LHY 6  perfect for you 

nothing at under $600 has. Precision clock ,LPS power supply and low noise regulstors, the cheapo $20 are junk and just make more noise ,your end point 

Ethernet cable to your dac is most important  depending on budget,

Wireworld make a decent one for under $250 then you will hear nice improvements

"Ethernet cable to your dac"???   Is that what you really meant to write?
