As you're looking for better sound , and all your gear "stands" on the electric power my suggestion is to not dismiss the quality of your duplex wall outlet . It was one of the LAST things I replaced , yet had the highest performance/ cost ratio .
After a lengthy search I chose the cruzeFIRST Audio Maestro outlet . It offered quieter backgrounds and enhanced micro- and macro-dynamics with clarity and no editorializing . More life .
Not the cable answer you wanted , but my experience of improvement .
I use only Analysis Plus audio cables , homemade power cords using Oyaide Black Mamba cables due to cost restraints .
