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.

I used MCRU LPS with my Chord 2qute.
The result was a very odd, unbalanced, not organic, unmusical sound.
As result I sold this LPS.
Mytek recommends it for the Brooklyn, but if it was an improvement, it wasn't quite worth the complexity. :)

My Exogal Comet DAC has an optional power supply and according to Exogal : It provides plenty of power to stretch out and render the highest highs, drive the deepest bass, and lets the Comet provide the richest, most authentic sound stage of any DAC on the market.
I went for it :  )
I'm using a TeraDak DC-30W LPS from Taiwan ($100++) for my Chord and it does the job; I hear the difference. 
I have a Qutest as well. Started with the wall wart, switched to a battery, then got a Teddy Pardo LPS. The Teddy Pardo is amazing, and I've bettered it by using a deep cycle battery and pure sine wave inverter to get completly off the grid(for the backend of my system).
