Linear Power Supply

I am thinking of venturing into the LPS world for a Wattson Madison ( original edition ) DAC-streamer that I acquired for a second system.  Rather surprisingly, I tried it in my primary system ( Leben cs600 and DeVore O93 ) and found it sounded superb and more enjoyable than my Electrocompanient ECM. Given the fact that it comes with a wall wart power supply, I thought a LPS might improve its sonics further.  In the course of doing some research I found a wide range of "sonic" characteristics in the different LPS available in the 500-1000 dollar price range. The potential power supplies I researched include Linear Tube Amplifier, Teddy Pardo, Fidelizer, Farrad and SBooster to name a few.  My goal is to improved bass response and add to the natural organic tone of the Wattson.  I am curious as to what others have found in their searches.
