I've been skeptical of power cable upgrades for a long time, but this winter I gave it a try. I started by borrowing a cable and using it with my Krell integrated amp. The change in my system was profound. I left the test cable in place and waited for my wife to notice without saying anything to her. She picked up an improvement immediately. Since then I've replaced the power cable on my CD player as well. The combined improvement is clear and I'm really happy with the results.

I just upgraded the power cable from an upgraded power receptacle on a dedicated line. The difference was astonishing based on just 1 power cable from the wall outlet to a grounded power strip - much lower noise floor, greatly expanded 3D soundstage and elimination of harshness in the higher frequencies. I have no idea whether this particular configuration would optimize any other audio system.

I am so lucky that I had a DC hum from the transformer in the first HiFi integrated amp I bought, so I got a Puritan PS106 DC power conditioner, with Puritan power cables. Aside from the fact this eliminated the hum completely, this also introduced me to the importance of cables and power supply in general. Garbage in = Garbage out. Cables in general also play a big part in the noise reduction, also in the time domain. This is I believe one of the reasons why integrated products and active speakers in general sound better compared to similar priced separates with “standard” cables.

It was quite an eye opener. By the way, the rep recommended that the preamp be the first device to be upgraded, followed by the power amps. Hearing is believing.

Rather than arguing whether the power cable can or cannot induce noise elsewhere in the system, let me just accept that for the sake of argument and ask a question. An engineer that I once worked with developed circuits for scientific instruments where small voltages and currents were significant. Making test measurements was challenging because noise pickup in his test probe cables could affect his measurements. He showed me the trick of carefully and neatly coiling the probe cable. You then give the coil a half-twist so that you now have a figure of eight. Finally, you bring the upper and lower loops of the eight together. You are now holding a coil of smaller diameter in which half of the loops go one direction and other half go the opposite direction. Induced voltages will have opposite signs in the two sets of loops and therefore will cancel. This allowed him to greatly reduce noise picked up in his probe cable. You can put a metal bar in the center of the coil to increase the inductance to facilitate cancelation. Since emissions from the opposing loops in a driven cable will be out of phase by pi, emissions should also cancel. Thus, if power cords are a source of radiated noise, wouldn't this coiling trick work for a power cord as well?

These machine have modules that communicate between a work platform control station and other modules at the base of the machine that ultimately convert operator inputs into machine responses. On the can bus of these machines, the communication wiring in the harness is shielded via foil and/or a surrounding braid to prevent cross-talk/interference/etc. When a "high end audio cable" a meter or two, (or three), in length matches or exceeds the replacement cost of a multi-conductor control harness for an aerial work platform that's 150'+ in length....people ARE being ripped off.

The problem with a UPS is that most are not designed for audio. I tried an expensive large (1050 watt ) UPS in my audio system. It robbed the sound of bass and everything became thin and zippy sounding. If I used it for video only ( graphics grade projector) I could see an improvement in the picture. Sometimes the cure is worse than the disease. While it appears only shielding has been mentioned as a cause of improvements made by aftermarket power cords, it is not that alone. The purity of the cable, the quality of the female and male ends etc. all influence the sound quality. All my power cords are shielded and yet they all sound different. Some warmer, some more detailed, and one has a very low noise floor. I mix and match to tailor the sound of my systems.

I think the explanation is reasonable, however, it seems to depend a lot on the actual construction of the amplifier. Say you provide a shielded powercable and your interconnection cables are also shielded. INSIDE the amp the leads of the power cable or terminal that go to the transformer may be shielded or may not be. Same goes for the inside part of the RCA terminals. So it might be that shielding the power cable on the OUTSIDE of the amplifier might, depending on the construction, not have an audible effect.

It's a long time ago, but. The shield needs to be grounded on one end only. I would prefer the wall outlet. So you need ground there for the shield. if the shield floats (not earthed) it becomes sort of a repeater. The grounding of the shield on one end is why some cables that can be connected in two ways (because plugs on both end are the same) are "directional". Remember, what comes out of your speakers is AC, rectified and next modulated by the amplifiers in the chain. Now any signal in AC that the rectifier and regulator cannot filter out comes as potentially audible noise out of the speakers.

Thanks Hans, very informative video. Quick question: one of the things I am going to change is the amp power cord plugged into a power conditioner... I am thinking perhaps to try the power cable first without the conditioner then try again with the conditioner. End of the day if there’s a significant improvement to the sound you’re after invest in both power cable and power conditioner... otherwise just power cable... Is that a good plan? Thanks.

Hi Hans, greetings from Argentina 🙋♂️ I found your channel a few months ago and I've been following you since then because I found it very educational and with very interesting data that others don't mention or go into. Regarding the issue of shielded power cables, I would like to ask you what is the conductor thickness that you consider ideal and if you think, as some recommend, that joining two separate cables for each pole is good to reduce resistance and inductance. Thank you in advance and congratulations for your channel 👏👏👏👏👏

I have a Musical Fidelity Tri-Vista 300 amp. This machine has the power supply separated from the amplifier, and power is delivered from a (to my knowledge) twisted, shielded cable. I have the amp separated around 1 meter from the power supply. Would i benefit from premium power cables to the power supply? Currently, all i have is a thick cable that came with the amp, connected to a Supra MD-06.

exactly. power cords make the biggest difference in sound quality! but it took years for me to find out. since i startet to use nordost cables my system is getting better and better. just try the nordost heimdall 2 power cords for the beginning...the music will start to live! dynamics increase, lower noisefloor, more details...just everything is better. the magnetic field what is around the conducter hase to be low. this field is a brake for the current. the more conducter you have the less braking it gets. but only massiv conducterd are superior...strand is crap. do tue the skin effekt a silver plated conducter is also much better. nordost realy knows what they are doing. this always sound like advertising🤣...but give it a try. almost eery system i tried it took a benefit from it. even cheap systems, because the music starts to live and you can hear this effect even at lower end systems. i brought these cables to my cousin...he instandly hear the difference, now he also got nordost cable...same with my brother. its just crazy. you are getting from "hifi" to high end! these csble make your system sound great. the higher the cable line, the lower the limitation of the frequence response. for my part the frey 2 was the most bang for the buck...you dont need much more thsn this power cable. the interconnects of nordost are also very very good! the same effect! but also just try norse series...but if its to much resolution for your system than try a leif series interconnect.

Hans, your clarification makes perfectly sense! I have made DIY twisted and shielded power cables for all my audio components. BUT I have learned that when connecting the ground shield of the cable, it should only be connected to the wall outlet side and left open at the component side. I don't know why it should be like this but that's the way I have made my power cables. So have i got it wrong or should the cable shield be connected at both sockets?
@TheHansBeekhuyzenChannel7 жыл бұрын
It all depends a bit on the local grid but often connecting the shield on the grid side is a very good solution provided you use a 3 core cable and you do connect phase, nul and ground. Although some equipment doesn't use the ground pin in the IEC power input. Please make sure you do keep within your local regulations. I can't accept any responsibility for your actions (legal disclaimer)

Yes, twisted and shielded power cables make sense under two conditions: 1. Don't ground the shield to the component. 2. Keep a distance of 1/4 to 1/2" between the conductors and shielding, since shielding can constrict the sound (from PS Audio's Paul McGowan).

I'm a cable sceptic, what I would like to know is this. If power leads do make a difference, how long does the cable need to be for it to have an effect?. I' m assuming the cable must have a minimum length for it to have any effect. So at what point does the length of the power cord not make a difference? Is it just pure luck that the std one metre length is optimum, or would a three or four metre length be better? Let’s say your expensive power lead was 10 metres long and it clearly made a difference, would you be able to hear a difference if you chopped a metre off, then another metre and so on, until you arrived at the std one metre? Just asking.

As far as I understand it, and as explained in the video, it is the shielding if the power cables that reduces the magnetic stray in the audio cables. So the better power cable should be long enough to avoid that. Is the power cable isn’t close to audio cables anymore, it will have no effect.

Thank you, a clear and understandable explanation. Would you mind sharing your opinion regarding reasonable prices of power cables? Personally I am of the belief that replacing power cords with an increased cross sectional area of the conductors with let’s say a twisted, screened triple of around 2,5mm2 and the associated male and female connectors to facilitate the cable, should cost no more than £50 per item to manufacture. I firmly believe that this is the very upper limit of what even the highest end of the audiophile spectrum need to spend in reality. Power cables that are marketed at thousands of pounds would provide no appreciable sonic improvement and are pointless in my opinion.

Power cords do improve the sound. How much money can be wisely invested depends on your situation and how critical you are. General rules as you stated are not valid.

@@demonkey123 If we knew that, you wouldn't have to ask your question. That said, I may be able to give you some useful info. The first thing is, you can't ask if something is better. You need to ask, is there a difference? Abd if there is a difference, is it good or bad? Its subjective. Give the same power cord to 10 people and some will like it, some won't and some won't hear the difference. That's just the way it goes. One other very important factor to consider is price. Never make a purchase decision based on price. To insure sucess, a cable has to be installed in your system, in the specific application you intend to use it. And then you have to do some listening. If you are trying more than one cable, don't expect the most expensive cable to win the comparison. Its perfectly normal to prefer a cheaper cable over an expensive one. I own several expensive power cords, but the truth is, the stock cord sometimes sounds better (to me) than the high end ones. So that's what I use. In the end, it just comes down to the fact that we don't have all the answers. You have to use your best judgement and be responsible. If you don't hear a difference, or see the value, don't spend the money. And you're talking to someone that has a pair of speaker cables that cost almost 4k for an 8 foot pair.
