[QUOTE="Ampdog, post: 77870, member: 144"] To try again (carefully this time ...): No passive electronic component is directional. Each passes current the same way whichever way it is round. (Current actually does not go 'from A to B'. It goes in a circle, reversing every half cycle in the case of ac.) Any audio signal is periodic, i.e. to give a sensation of tone/pitch, it reverses many times even for the shortest audible interval. Further, if one should snip out a small sample from any music and store it (as is possible with a digital oscilloscope), analysis will yield the same result irrespective of where it starts; at time A or a half wavelength later. (This is a theoretical picture - a half wave at what frequency? ... but hopefully the idea is grasped.) Thus to get enough information for an analysis, Joel, we're back to good old blind tests, with enough samples to be able to draw a conclusion. Also, any person hearing the difference mentioned in the first sentence of the quote must be given enough samples to try and sort matters out. It remains a puzzle to me. I did not google to try and find other history - anybody did so? I would really like to know what exactly is going on here. Now to carefully tap the right key this time .... [/QUOTE]
