The PSU negative rail is presumably what should be at a system-wide ground potential, I guess, but my analogue ground reference is about 6v above that. I was going to run incoming signal ground to the analogue ground ref via a decoupling capacitor, but I suppose I could just connect it straight to the PSU negative rail, if that''s what you mean?

•"Line-to-ground" line filter capacitors should be replaced with Y2 or X1/Y2 safety capacitors. (do not use X2 type). A Y2 capacitor can safely be used in place of an X2 capacitor, but an X2 capacitor should not be used in place of a Y2 capacitor. This is because, although an X2-type capacitor would work and filter noise sufficiently, it ...

They are classified according to their use in the circuit. Capacitors connected line-to-line are called "X capacitors," also called "line to neutral" capacitors. Those connected from line-to-ground are called "Y capacitors," also called "line bypass capacitors." X capacitors are used for differential-mode EMI filtering.

A line filter works by using a combination of inductors, capacitors, and resistors to filter out high frequency noise from the power supply. The inductors and capacitors act as low-pass filters, allowing only low frequency signals to pass through, while the resistors help to dissipate any remaining noise. 3.
