Replace wall wart to Simaudio LP3

I just picked up a brand new Simaudio LP3 to go with a second turntable I am setting up. The wall wart that comes with the LP3 is miniscule and is bound to be a switching power supply. I want to replace it with a premium quality power supply and would be willing to spend up to $750. These are the options I am considering; Welbourne Labs ($240), Bolder Cable Company ($550 for basic), and two UK options, Little Pinky (~$300) and Paul Hynes Design (Scotland-~$300). Does anyone have any suggestions/tips/advice? For reference, I already have a Simaudio LP5.3 mated to a VPI Classic and Benz Glider. The LP3 is to be mated with a restored Thorens TD124/SME 3009 and Ortofon 540MkII.
