Linear Power supplies for DACs...?

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. 

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.
