Uh, then why did you say,
“Those are interconnect cables, which are entirely different than speaker wire.”

deal. No one ever suggested there was a standard for directionality.
Recall directionality is sound related only. Duh! There are no technical
standards for Polarity, for soundstage, for realism, for room
acoustics, for speaker placement, for vibration, for RFI/EMI, for Noise,
for Distortion, frequency response, dynamic range. Yet somehow we are
able to find our way. Well, sometimes...fortunately, directionality is
often the easiest to get to the bottom of. All you have to do is reverse
the cable or fuse, whatever. Fortunately some companies control
directionality, even for power cords making it pretty much a no brainer.
No comment. I wouldn’t hold my breath for a MIL STD for directionality
any time real soon. 😡 Sound waves, as well as their electrical interpretations are sinusoidal, not directional. So is AC current. That means that first they are positive, then diminish, go to zero, increase as negative, peak, diminish again to zero, cross back to positive, grow to a positive peak, ...... wash rinse repeat, ad infinitum, ad nauseum. So if your wire is directional, then one half of your music is ALWAYS messed up. Ever watch your speaker cone. See, it goes out. stops, goes back, stops.... Same with your AC cord. Don't think of it as a firehose, but as a two man cross-cut saw. First lumberjack A pulls on it, and then lumberjack B pulls it back. Back and forth. Next thing you know, the tree is cut in two, work is performed. Not like a chainsaw, where the chain only goes in one direction. Chainsaw=DC. AC is more like having two hoses each interacting through pistons with a mechanism on each end, say a cross-cut saw. You have a two pistons, each driving one end of the saw. When we push a piston down on hose A, it pushes on cross-cut saw end A. When we then push on Piston B, it pushes on the other side, pushing the saw back. No water ever leaves the system, but energy at one end is transmitted to the other end. That energy can be transmitted into the system by using a simple cam pushing the pistons back in forth with a circular cam driven by a simply water wheel. This is why AC power transmission works so well. The AMP is outputting a sinusoidal waveform. The output of the AMP is still positive-negative-positive-n-p-n-p-n................... Again, slap the output onto an oscilloscope, watch, and learn. The only electrical circuits I know of that don't cross zero are very high speed ECL chips. Those move from -2.2V to -5.2v for digital circuits. The price you pay for this unique feature and the blazing speed, is a chip that will fail in less than 10 seconds if not actively cooled. Chips go faster if they don't have to reverse the flow of electrons, but just change the pressure (voltage) in one direction. SO, please explain how your cable directional. If my explanation doesn't convince you, try making a little test board to put between your amp and your speaker. Just put a simple diode in line with the signal you believe to be directional. That will force your signal to be directional...... Oh, I don't recommend it, cause I don't know what a series of positive only electrical pulses will do to your speakers..... I suspect it will be nothing but bad......... But then, I'm only a degreed engineer from a podunk school like GaTech, who spent his entire career building electronics and if you ever heard me sing, I have a tin ear. As I used to tell my management, knowing is much better than thinking, but stop thinking, cause you're not qualified. Cheers |
This thread is similar to most of the UFO conspiracy ones: people endlessly argue the topic but the most forget that it is not a topic of science because it deals with individual and often isolated experiences and may involve unique perception states. It is, again and again, paraphrasing Pass, the case of Sommeliers relying on Chemists. Let’s, at least, agree that: 1) Hearing perception, as any other cognitive functions, is relevant. Case in point: I have a friend with a sort of superhuman audio perception (confirmed by tests) who prefers a certain level of emphasis in the midrange (including sibilance range) while I can’t tolerate it for more than a minute. I have a simple explanation why that might be the case: he hears much more in lowest and the highest range of the audio spectrum so it is only natural for him to emphasize the mids to normalize it. In short, if a cable sounds better even for a single person in their own system after they spend hours of listening to a wide range of material (or they spot a UFO and are not known to hallucinate) that alone ends the topic for me. 2) No audio-path component can be evaluated alone and should exclude the original sound source or space we listen to it (or headphones we use). Case in point, the same component may have a different impact on another component in different systems and may result in a "worse" or "same" or "better" experience for various listeners. One question, however, will remain: what is "worse", "same" or "better" unless it is A/B-ed with a wide range of live sounds in the same listening space (preferably including human speech too). If the majority of listeners hears no difference after changing a cable in the same system ad after they spend hours of listening to a wide range of material (or they never spot a UFO) that does not surprise me either. |
