Bypassing the input voltage divider to the LMV321 opamp instead of the VREF output to see if this is a better solution than the VREF bypass.
TLDR; It also works, but has a small issue with overshoot on very small capacitive loads.
More experimentation required.
(Waveform fidelity confirmed with input probing)

Dave found two issues with his Focusrite Scarlett Solo.
Conducted mode USB noise when you unbalance the monitor outputs.
And the headphone jack not muting the monitor outputs.
Plus a demonstration on the importance of using balanced audio leads.
