I'm getting there. It's a lot of gear, and spaghetti, as you say, is meant to be eaten rather than electrified. Switch, NAA and Computer all need power supplies (3). Wifi extender (1) as I can't run a cable from my main router, (3) CAT 6/7/8 UTP ethernet cables to and from the switch. USB cable. (7 cables so far). Power cables to amp, Node and DAC. (4) RCA cables. 1 coax and a partridge in a pear tree.
Switch is the part I'm struggling with. Apparently an external power supply is frowned upon, but Internal power supply (whatever the heck that is --doesn't everything have to be plugged in to the electricity somewhere?) switches are expensive and of course you can't have anything with a fan because that generates electrical noise.
Lastly, where and how in squid's name am I going to put and power this? I've got two wall outlets, one on either side of the room. A power strip for each one. DAC and Node go on one? Mac, switch, and NAA on the other? where does the VTL get plugged into? ARGH!!
And then we are moving to PRG in 16 months.
