Is it worth soldering 5v power direct to DAC2 HD board & DAC + pro


I am happy with the sound of the DAC2 HD, but is it worth getting/paying a professional to solder power cable directly to the DAC board. I was thinking of doing the same to the DAC+Pro as suggested by the Hans Beekhuyzen channel. I like to tinker, if there is a chance of some  improvement. I am using budget  linear power supplys from Aliexpress. https://www.aliexpress.com/item/32919308039.html
