Any one try the new Synergistic Research BLUE UEF Duplex receptacle?

Jea, Your point is fairly taken.  However, there is some "science" around power cords and interconnects, to name just two elements.  Power cords may be heavy enough in gauge to transfer the current needed by the component, or not.  They may be shielded, or not.  They may be configured so as to be capacitative and/or inductive to one degree or another, and there are some known ways in which these properties could affect sound.  Likewise for ICs, if you delete the bit about current carrying.  Plus, as you suggest, I rely upon personal experience and the reports of a few trusted sources as regards these and some other ancillaries. But in the case of the SR AC outlets, we have.... what?  What is there about a black AC outlet that would make it sound different from a blue or a red one?  (Obviously, there could be differences that I don't know about, but why doesn't SR tell me about them, is my point?)

What I would want to know, if I was in the market for changing out wall outlets in order to change the tonal balance of my audio system, is what is the science behind ANY of the claims made by SR? From what I can see on the SR website as regards these outlets, bald statements are made describing the "sound" that your system will have, with absolutely no rationale to support any of the claims, no scientifically plausible "mechanism".  I am not categorically against tweaks.  I do believe that power cords, interconnects, speaker cables and other more surprising elements of an audio system can affect sound, but if I am going to spend $200 on a wall outlet (or a similar amount on a fuse), I need to know more.  (Of course, with the fuses, we are told there is some sort of quantum effect; that makes me feel a whole lot better....not.)  I have no axe to grind.  Tell me what point I am missing. If it's merely that the buyer installs the wall outlet and then hears a difference, that's not good science. The observer is a reader of internet threads like this one, which creates a certain expectation of the results, and he or she has paid good money for the new part; the bias is built in. (And by the way, there is some danger associated with amateur electricians messing with wall outlets.)
