In Reply to: I was as doubtful as you are until I heard the difference posted by Norm on November 10, 2004 at 13:09:27:
Norm :""I once even went to the trouble to separate a cheap two wire power cord. I reversed on wire and cut it in two. I then reterminated one with the wall plug at one end and the other with it at the other end. I then tested whether I could hear a difference. It was not as audible as with the Omega Mikro, but it was clearly different sounding.""
Norm...you changed the hot to neutral capacitance, the inductance of the cord, it's susceptibility to RFI, it's impedance across the entire spectrum, and the strength of the dipole field it broadcasts for 60, 180, 300hz and up, all haversine components of the supply, as well as any coupling of audio signals and bridge rectifier (solid state of course) reverse recovery transients, as well as the integrated time rate of change flux which occurs between components and the interconnects which connect them...Other than those small items, your experiment was well controlled..
(my apologies for that last bit...it's end of the day, and I have off tomorrow, so I'm chompin the bit to drown some olives...)
Your experiment, while well meaning and really interesting, points out that in addition to the change you intended to test, there is a huge list of confounding changes you did not have control over that could alter the outcome of the experiment..Man, I can't wait till my basement lab is setup...
Cheers, John
