Upsamplers, DACs, jitter, shakes and analogue withdrawals, this is it.

RE: Roku 4 Power supply

Process of elimination. I'm using a PS Audio P500 Power Plant, and when I plug in the Roku, I get a hum in the system. Unplug it, hum goes away. There's no third prong on the Roku plug or I'd twist it off, and no grounding stub on the Roku. Switching power supplies are noisy, so I though a cheap linear one would be something to try. I've had this trouble in my system with the Squeezebox stock power supplies, which I replaced with CIAudio linear upgrades to good effect. These were very nice sounding additions by the way.
