I don’t know if anyone mentioned it already but given that wire directionality is important for fuses in AC circuits doesn’t it stand to reason that wire directionality comes into play for power cords, too? Just curious.
powercords
I certainly have, personally, experienced the improvement power cords can make on amplifiers...how about their value on other items, such as preamps with external powersuppies, and phono preamps....I know better than to apply layperson logic, which doesn't always work in audio, but it would seem that items that draw less "juice" would be less prone to changes in power cords....thoughts welcomed, but experience more interesting to me.....thanks

In my main system, I do hear an improvement with good upgraded power cords however I hear much greater improvement on all my other components.
I am not sure if I can hear subtle sonic gains with my new 12 gague DIY power cords to my amp and CD player,,1st I need to get my resistors swapped back to Jadis' original metal takam res,,right now running Carbon Film = not the same. Its ~~smoother~~~ but a bid draker = warmer = less psrakle. I will say, cut your basic 50 cent power cord that comes with every amp/cd player you purchsae,,Now compare that hair thin gague vs my 12 gague Home Depot wire. Sonic gains?? maybe,,But i do feel more confident both units are getting all the juce they need to run efficiently/effectively Here you can see my power cord go to second 40 to see the DIY power cord a tech guy may say ~~I tested both the 50 cent cord vs the 12 gague heavy duty,,,= no volt couurent dif, both the same~~~ = snakeoil. The 1 is 12 gague, the 50 center is like 20 gague,,,,a tester might show equal,, but in real terms, not the same. The amp will respond superior with 12 gague vs cheap 20 gague. https://www.youtube.com/watch?v=t_Y9WRTjl9c |
At one point many years ago my turntable was battery powered. The battery was connected to a charger. The thing had a switch to disconnect the charger from AC. The darn thing sounded better disconnected, even when the charger was not charging. I never bothered to try changing the power cord to the charger since it didn’t matter because I could disconnect it anyway. But this is a perfect example of how the power cord connected to an external supply can still affect the sound of a turntable with a very massive platter. Currently the power cord going into the Verus motor controller is the least effective of all the power cords in my system. Likewise the same SR Orange fuses that make a substantial improvement everywhere else matter hardly at all in this controller. That said, the power cord and fuses do make a very slight difference. Nowhere near what they do everywhere else. Barely noticeable. Would not spend the money if I didn’t already have the power cord. But its there. As to how, it should be obvious. There’s two explanations. One, as with the battery that sounds better disconnected, the power cord can act as a sort of filter that reduces AC line noise. Another is the motor is like everything else in an audio system, it does not draw power continuously nor smoothly. Its a never ending stream of transient micro-surges. Even as massive a platter as mine (25lbs or thereabouts) still responds to motor torque and speed, which in turn derives from power delivery to the motor. These "I’d like to know how" questions might seem intelligent or intended to stump but are actually quite tiresome. You really should be able to figure this stuff out for yourself, you know?
