hospital grade or commercial grade receptacles ?

Tbg... excuse me? I wouldn't know science if it bit me? And you're arguing that something outside of the signal path, that has no measurable differences whatsoever compared to another fully functioning device of the same type, can have subtle effects on things like soundstaging? Give me a break! That's like being called unscientific by a palm reader.

Tobias... run the test yourself man. Jeez. Go for it. Report your results. 20% faster would require a 20% increase in power transfer. Maybe UHF was testing against a 30AWG power cord.

Robin, the basic activity of science is *observation*. In this case, *hearing*. Shut up and listen to the music. Nobody has to explain you nothing. For years scientists thought Liebig's law of the minumum held. Not so in aquatic ecosystems. When I go to the field I *observe* first, then use my instruments and analyze the data. That's how it works.

For the record, I am a scientist, a beta tester for a few small audio companies and a keen observer of women's phenotipe makeups.

With psychic power, primal intensity and boogie factor,

Irvrobinson, this palm reader would call you a flat earther, who totally ignore all the observations that suggest the earth is round. Given what you say I would again say you are not and would not know the scientific method if it bit you.

It is you, sir, who have psyched yourself into not believing your ears. Enjoy your Radio Shack system.
