I've run it on as little as 10W (device showed about 6-7W on my network, using a PoE to USB adapter from Ubiquiti).Agree on everything save the adapter. Canakit’s adapter is 3.5 amps. don’t know how much stress Roon puts on the Pi, but better safe. And at (eek) amazon, you get a free inline power switch.
The only reason I recommend those is their relatively clean power.

Granted the onboard regulators in the rPi plus the good USB implementation on the Schiit side should make it a non issue.
That being said, the abhorrent quality and design of some USB supplies does terrify me. Between poor Line to Low voltage isolation and low quality components some USB supplies should be avoided for health and safety. Don't need any fires or shocks from a crappy USB supply, it's worth $10-20 for something that would catch fire, shock you, or fry your connected device.
