Ethernet Switch

Congratulations on your new digs.

I tried an expensive Melco switch and compared to the bog standard Linksys I couldn’t tell a difference and fortunately was able to return it for a small fee.  There will be many posters here with different experiences 

With that many circuits, the Netgear switch is probably what you need.  Most audio switches have fewer ports, I think 8 is most I've seen, mine has 4.  

if you feel you want the isolation of an audio switch, you can put it at your music room.

I think , it is 1000mbps

Try putting a good audiophile ethernet switch right in front of your streamer.  It can make a huge difference in a resolving system.  Examples are GTT Audio Dejitterit, JCAT M12 gold or Premium and Network Acoustics Tempus.  I have had all of these in my system and they all improved things.  I currently stack a JCAT M12 Gold switch going into the GTT Audio Dejitterit Switch.  Others may not believe, but I hear the improvements.  

I think how much / if you will hear a difference will be dependent on your streamer. The better the streamer the less likely you are to hear a difference among routers.
