Linear Power supplies for DACs...?


Is there real SQ benefits or is it placebo snake oil?
i have a Chord Qutest and it has a wall wart. Lots of people say there’s real benefit to adding an external LPS. 
Plenty of choices ranging from $50 - $500.
Sure, a home audition is ideal.

but, what do you guys think?

Not just for the Qutest, but in general for DACs.

The noise issue with switching supplies is primarily common-mode. Fitting a common-mode filter on the DC feed to a DAC would be sub-optimal, its best position is on the mains side. Anyone got example DACs with CM filters on their power inputs?
