![]() ![]() ![]() You are being baited into a worthless debate by an OP who makes a practice of this kind of thing. Interestingly enough, my guess is a well designed power supply, the less it is susceptibleīeware this thread. It's possible a lot of these audiophile power cables help to improve the power factor of the power supplies to make it more stable. I am not a power supply designer so I don't know the detail. What you want is to have more "capacitive power factor", less inductive. With all the advance, there are still a lot of things in electrical current we still don't have a firm grasp.įor this case, one explanation I can find it something call "power factor" in power supply designs. You sort of have to find different analogies for different situation depending how you feel comfortable with it. Based on experience, basically there is really no one single analogy that will fit all situations. Need to have a more advance analogy to understand electricity. So most students would find out soon that he or she Of electrons so it's not like the reason is a good power cable can supply more electrons - like water. I mean the analogy is useful but obviously it would't work in this case for obvious reason - even with a bad power supply cable, there are plenty Most student early in their classes learnt that electrical is like water. Before going further, let's take a step backward and talk about how we sometimes making analogy to a electrical current. Now the hard part, so how can we explain? Why can just a few feet of cable make such a difference? I mean the electrical current has travel literally hundred of miles before getting to your house then how in the world can the last 3ft or so can make any difference. Probably no fancy dielectric.Ī: PS Audio PerfectWave AC-5, 10-Gauge Power Cable, 2.0M (6.6FT) - 15 AMP IEC: Home Audio & Theater The one I bought seems to have a rather simple 3 wire constructions of 10AWG gauge. The PS cable seems to have a much more sophisticated construction with multi-strand filaments and what looks to be some fancy dielectric too. now I think of it the cheap one I bought does lack a bit of transient. I was looking around in Amazon and found the PS audio power cables being sold for $400. I guess my recommendation is at least you give these a try since they are rather cheap, you won't loose too much money if it doesn't work out. Again it might be a matter of retuning my speakers. There is slightly less treble but maybe because there is more bass so subjectively you hear less treble. Maybe I have to lift the 1khz - 3khz range a bit. Maybe I have to retune my speakers to match the new power cables. Since there are more bass now, I had to pull my speakers a bit further from the wall so the sound balance is now different than before. I mentioned "better damped", but may be a bit "over damped"? The sound is a bit leaner especially in the midrage. You can hear more into the soundstage and so on and on. The sound is better damped I think, less overhang. But any way, as for the sound, there is a huge jump in the bass, and I mean "HUGE". So with these cables, in term of construction, they are like some big water hoses. That was like a year ago, but only recently I thought I bought a few of these to try The music was better organized and so on. I never expected any difference but to my surprise, especially on large scale orchestra, there was definitely more weight on the low end. The previous cable was slightly thinner than the cable I had just swapped in but other than that, they essentially looked the same. I then was cleaning up and rearrange my system and after that I just randomly swap out the cable for another. ![]() The first time I had an experience where a power can make a difference when I was using my trusty Arcam cd23 with just some cheap power cables I just had laying around. I included the link below.Ī: WAudio Hi-End Hifi Audio AC Power Cable Power Cord US Plug - 6.6FT (2M): Home Audio & Theaterīefore getting into any technical details, I want to describe the difference in the sound and at the end, I just want to make a stab at why just a few feet of cable can make a difference. First, I am not affiliated in any way with this online vendor. ![]() On a whimp, I bought a few of these power cables from Amazon for a rather cheap price - about $48 each depending on the length. ![]()
