I didn't see you explain anything.
Maybe not but the effect of improved PS on computer audio sound quality IS well established, repeatable and marked. That this is the case has been reported by literally scores of list members; why it is the case has been discussed a score of times by competent commentators. Try spending less time popping at fmak and more using the list's search facility . . .
It's less that a given PSU is linear rather than SMPS and more that it is well designed regardless of technology. One significant issue is that typical stock PSUs are notorious for noise polluting their mains supply (thereby degrading the rest of the system) whereas better units tend not to.
A linear, choke-based design published on the forum by John Swenson for powering small motherboards is pretty basic as far as load regulation goes but focuses on reducing mains pollution. Going from a stock SMPS to the Swenson design gives a major SQ boost on appropriate equipment, snide remarks about "audiophile" pricing notwithstanding. (A DIY design, it costs less than £70 <$100.)
