Jitter over digital outputs for different WiiMs

[hgo58]

A very good explanation of jitter here: https://audioxpress.com/article/audio-electronics-is-digital-jitter-really-a-problem

"The usual scapegoats “fullness and width” are clearly not affected by the addition of jitter noise. Even with the jitter at 10µs, which is huge and limits the signal-to-noise ratio (SNR) to only 35dB, you can appreciate the power of the masking effect. "

If Rob Watts is right about this ( he probably is ) then the audible changes should be what you describe.
This is also my experience when experimenting with different power supplies - less RFi ( both in SMPS or LPS) = a more relaxed and slightly darker sound.

I use an iPad connected to an external DAC and following Rob Watts advice I compared a direct USB connection (iPad on battery) to a USB connection via a charger adapter (Belkin product sold by Apple). I observed what Rob Watts claimed; non-powered connection, smoother with better sibilants and powered connection slightly brighter.
