Here is the Ethernet switch , and the Pangea is a perfect match ,
thats is not even close to Accurate , having owned a Audio store you are getting less then $500 in parts counting the box , not high quality what so ever
compared to say a $3500 innuos SS hd and streamer it destroyed in its decent in the $1200 range but you get what you pay for ,Thst $10 horrible wall wart is pure noise, just try putting a good LPS power supply on it a Big step up with as mentioned above a decent power cord like the Pangea ,and the modem- router combo a good LPS look on the wall wart on bottom it’s normally 12v 4 amp
I put the $700 Linear tube Audio LPS which comes with a excellent DC cable others charge over $100 for plus I put a 5 amp slow blo synergistic purple fuse and Pangea power cord , that made a big difference streaming to complement the link below for respectable Ethernet hub.
