Why do I need a switch?

OP:

The ifi iPower adaptors should work well and minimize AC noise generation. RELATIVELY affordable given the usual markup on anything that says "audiophile" on it.

I run my DAC on a Power X version, and then use the next level down for my streamer, and network switch in my HT.

I’ve been using the for about a year and it works great!

NETGEAR Powerline adapter Kit, 2000 Mbps Wall-plug, 2 Gigabit Ethernet Ports with Passthrough + Extra Outlet (PLP2000-100PAS) https://a.co/d/0pfP5NU

One out goes to the integrated and the other goes to the server.

I'm not overwhelmed by iFi. I prefer something more conventional like these:

AUDIOPHONICS PSU-HC Regulated Linear Power Supply 5V 5A 60VA

AUDIOPHONICS PSU-HC Linear Regulated Power Supply 12V 5A 100VA

If I change the 9v PS’s,  I’m hoping to find one LPS, with two outlets. Use only one AC plug, less clutter.

My DAC has a LPS built in and I bought Teddy Pardo for my streamer, but it’s got a special cord and it’s 5 volts and these little guys need 9.

Also that article is interesting. But I wonder which is better, the fiber or the capacitor route?
