Power cord? Why?

There has long been "discussion" about whether psychic (mind reading) powers exist. Many experiments have been done using valid statistical methods to see if a subject is doing better than guessing about things like a selected playing card. Results are inconclusive. However, if one scientist could find the MECHANISM for psychic power, perhaps some kind of electrical wave traveling between people's brains, all the sceptics would be converted.

So too about power cords. The reason to look for the electrical characteristics responsible for sonic characteristics is to fix the problem. Thousand dollar power cords may not the the best solution.

Of course the 115VAC power lines also carry some HF modulation...simple table radios often use their power cord as the FM antenna. It's doubtful that any such HF would get through the power transformer impedance, and if it did it would be shunted to ground by the power supply capacitors. What's the impedance of 20,000 mfd at 20KC? Ziltch. If this isn't enough, put some ferrite beads on the power input wires.

If your digital electronics GENERATES noise that propogates through shared power lines to other components you need a better digital electronics design. Fix the problem at the source. (Frankly, if I were digital noise I would travel by the signal interconnections).

What is a "closed mind". I think it is one that dogmaticly argues for some point of view as an article of FAITH rather than as a result of LOGIC. For some, I guess, audio is a religion.

Psychic powers do not equal--nor have anything to do with--mind reading. If my mother read you the cards you'd be surprised. I, on the other hand, don't have that specific gift. I can sense the present and my surroundings very well...sometimes "too well".

And yes, power cords have an effect. Whether you can notice it or not depends on your hearing and your system. I hold the view that as power delivery/noise control improves, expensive power cords are not needed. They could actually be deleterious by acting as filters and limiting extension.

I suppose it would be totally out of bounds at this point to say that I have gone beyond AC power cords, and found that even in straight flat DC power, I can hear differences in the types of chemical compositions of the batteries being used. Not only does the wire matter, but whether there is a Ni-Cad, Lead Acid, Alkaline, or whatever kind of battery being used. I use DC power for most of my system, and have experimented with different battery types, and believe me, they are audibly different. So, is 12v simply 12v, or is there a difference?

Science is to be used to explain why things happen, not to be used to say that they can't happen because the scientist can't measure them. A real scientist would expand his study and abilities to find out why there is a sonic difference, and not stand on previous ideas that cannot explain the phenomenon. Science is learning, not the refusal to learn.

Viridian - the point is that if you cannot measure anything, then your mind may be playing trick on you or you have not gotten to the root-cause of the sonic change. At least if there are measurements that coincide with sonic changes, then theories as to why the changes happen are more feasible. It provides some basis for explanation.

Batteries, like AC power sources have impedance. Some batteries will have lower internal impedance than others. Some will work well during transient current demands and others will not work as well to provide the transient current. There is no surprise here.
