Upgrading Power Supply for Lumin U2 mini from switching to Linear Power Supply

Recently purchased a Lumin U2 Mini streamer along  with a Chord Qutest Dac. Use Qbuz and am very happy with the sound quality. My speakers are Martin Logan 11A Impressions, with a Rogue Audio preamp and a Conrad Johnson Classic 62 tube power amp with 60 watts per channel.

I spoke with my dealer yesterday who mentioned that he upgraded his personal U2 Mini power supply to the one supplied by Vinshine Audio. I watched the owner of Vinshine actually do the modification on U Tube. It involves cutting wires and in short for someone like me, there is no way I would even attempt this. I know that making this change voids the manufacturers warranty. This risk I am willing to take. By the way, the dealer mentioned that the improvement is not "night and day", but substantial. Better bass, blacker backgrounds, to name a few. The mod uses an adapter that goes inside the unit with the LHY Power supply which is made by Jay's Audio who also sells CD Transports.

Part II-I noticed that Upscale Audio also sells a Linear Power supply for the U2 Mini, which is made by S Booster.  The reviews claims it is easy to install. I am looking for a plug in and play. Am I asking for too much? Has anybody on this site modified the switching power supply to a linear power supply and how involved is this? 

Thank you for your responses.
