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.

Have gone from supplied wallwart to battery to linear power supply with my DAC. Each time was a noticeable improvement.
I too have a Chord Qutest.
I replaced the stock power supply with a Small Green Computer 5V Linear Power Supply ... and yes agree that it makes for a worthwhile upgrade.
chord insists not but i agree with you gents, i added a LPS to an old 2Qute dac and was improvement.  I have the qutest now also, small green good?  others?   would like to keep it under 200.   thanks
