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.

Yes, using a LPS is a noticeable upgrade for the Chord.

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.

The Small Green Computer 5V LPS goes for $160 + shipping.
It does the job. Only potential negatives ... it does run hot (I keep mine on all the time), and the blue LED display is rather intense.  If you check out my system in the Virtual Systems section here on Audiogon, you'll see that I have the power supply facing the side of the cabinet it resides in to minimize the intensity of the LED display.  Overall I give it a thumbs up.
