Power Cable Tech Talk and a little help for Amir at Audio Science Review

That's why they make a shielded cable for certain.. have a conversation with a military grade construction electrician in they'll set you on the right Paris I agree completely with GRE research but at the same time.. you do not need to spend a fortune on... Cable Cable

Just curious why don't you use Chokes on your power cables this would give you a totally null feild on the power cables Iam sure a decent manufacturer like TDK magnetics would make over sized chokes and one thing Amir and your video did show is how backward and poorly designed your A/C wall outlets are no space for Mov's and fuses and it also beats me why you have two different voltages in your house wiring has no one thought of redesigning your plug top plate ??? Iam a sparky in the UK so the earth is round

Would be very grateful if someone can explain how does the power cable filter/remove the noise/intereference from the electrical network before it?
And if a power cable can do that, then why can't the amplifier do it instead?
I have always thought that this is the job of a good power supply...

Amir made a great point, if your cables require 200 hours to become able to achieve what you claim they do, and assuming you desire to put the best possible product in the hands of your customers, why not plug them in and do the "burn in" there at your warehouse? 9 days later you'll have an actually finished product to deliver.

Ok I stopped watching when you said that cables need burn in. That is flat earther material right there. Geeez!

37 min of proving nothing………😂

Now let’s be reasonable folks. Just take out all your drywall and replace that pesky ROMEX. It just won’t sound as good if you don’t. While you’re at it, make sure you open the chassis on all your gear and change that wiring to all be 00 gauge and then change those piddly 3-prong sockets. Better not have any electronics in there; your capacitors probably have 18 gauge leads and that just won’t work. There’s no other way to get good sound.

How much do you know about power supplies?
Everything I have that needs a power cable has a power supply.
How does the noise and interference get through the power supply, and into the audio signal path?

There is a fly in the honey.

the only way to effectively air your differences is for Danny & Amir to a face 2 face discussion...?

I have a decent listening system (mytek Manhattan 2, benchmark amps, focal sopra 3's) this is all in a professionally sound treated room, I even had an electrician run dedicated 20 amp power cables and we he took great care to make sure it was separated from anything else in the wall. I have tried many different power and interconnect cables ranging from Pangea to audio quest to nordost....... I have had many local audiophiles come in and do blind tests and the unanimous conclusion is by a fancy cable for looks not performance. The biggest improvement came from the room treatment and speaker placement.

I'm curious. Why do you say, "those on the left", when talking about cable skeptics? What does left or right have to do with it? Is this political?

The fact that he keeps referring to the "flat earther's" as "the left" speaks volumes about this guy.

Electricity is noisy folks! No way around it, it just is. And! Electricity causes motion, it actually vibrates going through the Romex in your walls, creating more noise. And all of this can be transmitted to your gear. Anything we can do to diminish this FACT, is going to be good to your ears, and it is not always measurable. They put torque specs on the connections in your mains panel, and on outlets and switches for the wires, if not using stabs or lock connectors. There is a reason for this, over time these connections loosen, due to this motion, or vibration of electrical transmission. Bottom line, this stuff matters if you are in the hunt for better sound, or from keeping your house from having an electrical fire. Ethernet, it has the same issues, a good filtering switch will blow your mind in both audio and video, and you do not have to spend a fortune. Try a NetGear GS108Ev3 network switch if you stream, especially video streaming. This is a $50 switch, try it, I think you will like the improvements.

When you try to sell BULLSHIT and SNAKE OIL , WITH an agenda AS YOU DO, with ZERO PROOF, ZERO TESTING to back it up, you should be shutting down your MISINFORMATION CHANNEL! Amir is a legend, WITH PROOF and the equipment to back up, which we all know to be true, that you and your BS products are nothing more than a SCAM!!

This only shows how dangerous and agressive the trolls on ASR are - they 'think' they know things, well maybe a handful of people there do but others are just poor, extremely ignorant and agressive followers.

How much difference can you really get between a 200 dollar cable and a 2k dollar cable ? I had a chance to prove that the noise floor will be a bit a bit lower but to me it’s not worth the expense you can use that money to invest on the source ‘

Shhhh...don't tell anyone, but I built my own little nuke plant in my basement. Sure, it gets REALLY hot, but my power is clean as a whistle!

I'm so glad that I just turn on the music on my cheap, rebuilt RCA floor speakers, and enjoy the music.
Non of this worrying about power cables and such.
Non of the arrogance that comes with buying $2,000.00 speakers.
All done through a mid-grade Marantz that was bought on sale as a closeout.
I don't fret over the fact that the new crossovers dont use all air core inductors.
As someone with an electronics degree, I totally get the whole components make a difference thing.
But in today's economy where food and utilities costs have skyrocketed, I carefully choose the priorities.

Danny you say your power cable needed 200 hours burn in. When do you know it is past it's best considering it seemed to burn in before reaching it's best? If this is the case it must have a particular lifespan due to continuous current flow causing the cable to burn in and burn out?

Well, Nelson Pass supplies his equipment with what he calls “appropriate power cables” which are basically standard, but quality cables. Not in $$$ range. My Accuphase came with pretty regular power cable. For some reason I trust Nelson and Japanese more…

I think you make interesting power cables. i would sure like to try them.
I live in the Netherlands, is there a dealer here.
Further more i do not belong to the category of all the clowns reacting below. I know what cables do and what not.
I have pure copper connectors on mine. I think it sounds best because there`s no material in between.

if this is for AC power wouldn't' tit be better to plug into the outlet closest to the mains coming into the house bypassing the terrible cable that runs to other outlets? A chain is only as good as it's weakest link.

It's not the responsibility of us cable deniers to prove cables make no difference. It's up to cable believers to prove that they do. With lots of rigorous blind A/B testing.

This is hilarious 😂

Noise in cables is irrelevant as it gets filtered out (actually removed) at the power supply in the appliance itself. IT IS THE POWER SUPPLY in the appliance THAT REMOVES ANY AND ALL ELECTRICAL NOISE. It is NOT the electrical cable that removes any of the electrical noise induced in the cable. How can it do, IT IS JUST A LONG PIECE OF COPPER WIRE. If equipment is compliant with FCC or CE EMC requirements, it has to not ACCEPT or TRANSMIT electrical interference.

There is I suppose a hypothesis here that
1. Cables could measure differently/the same (capacitance?)
2. Cables could attract noise dependent on their construction or reject it
3. All cables could sound the same or differently dependent upon their construction or materials used

The question is how does or can the above measurably improve/maintain the output from the audio equipment which creates a true hifi presentation from the music source?

The main issue Danny has is that Amir measures whereby in terms of cables Danny is pitching a different case - primarily rejection of interference. Rejection of interference can maintain the audio signal since it could avoid distortion. But ultimately every listening room/equipment set up is not the same.

Dude. You're seriously using thick rope, then braid wire around it? For, what, making it look thick, because thicker is better? What material is that? Is it even flame retardent?

If all th noise ect. coming in your audio gear en u can hear it. Where this video is about. Maybe Audio brands do not engineering the product well enough or? Special in higher audio segment.
Its not bad using good shielded decent cabels, plugs ect. any budget.
Thank you,
People like highlight tech in the utube video's en are learningfull for the purist.
Greating from Eu

I always say flat earthers have supporters around the globe 😉
And so has the snake oil Industry.
At some time such nonsense made me sick but meanwhile i always just have to snort with laughter.
And while being some kind of atheist i thank god for not blessing me with such (expensive) stupidity anyway.
Ever messed with room acoustics, modes, treatment, loudspeaker positioning etc? And i don't mean coin sized stickers to put on things to "improve" that. Muhahahaha 🤣🤣🤣
I await the day where toasters getting upgraded with supreme power cords for a better roasting flavor. Evidence? I don't need that because it tastes better. And even power cords and interconnects for humans to provide "clearer, undistorted thinking", some kind of "pull away a curtain" thing. I mean the signal-to-noise ratio obviously is not that high within most. Needless to say it has to avoid skin effect.

what acoustic noise you cant compare with electrical noise.... what you measured is mostly random sound in your room. yes that wont line up, at least parts of it. you can do a null test. realtime for instance.

This video sounds like the presenter is selling snake oil.

You repeatedly referred to "receptacles" as "plugs". A plug is not a receptacle. Plugs are male, and receptacles are female. A “receptacle” is the “female” counterpart to a plug.

Measure water. It's always level

Double-blind testing. I've never seen a double-blind test showing an audible improvement for an expensive power cable. Until I see that test, I'm with Amir on this one. But I'll go with Danny on his improvements to stock Klipsch speakers. That improvement is both audible and measurable. It's like turning off the "loudness" button on an old receiver. The only audible noise I've ever had came from a ground loop. And that had nothing to do with the power cable.

i joined ASR as quickjack and posted seeking info about some Yamaha 6490 speakers ( the ones we are modding improving ) ! in several related areas, threads i posted something similar and thought it might stimulate discussion ina long dead thread and was falsely accused of being a troll and immediately banned ! this is absurd i am not and admin a dozen FB pages Amir is one of the most arrogant and obnoxious and unfair people i have ever met in m y life it makes NO sense to accuse me of that and ban me forever i am old and 100% disabled vet ( nam era ) and it would be nice to be able to read the reviews and info i have tried many ways to ask that i be forgiven and let back on to no avail this grossly unfair it is hard to imagine a man could be so cruel as he is . there is nothing i can do i feel an utter failure.

Why you dont make test of system with speakers with your cable and with standard cable?

Honestly it's silly to argue with a dump, especially with a dump who truly believes he is smart
This Amir guy may fooling his audience just to exploit their wrong beliefs for making a bigger following

It's really sad that people actually believe this guy. There was nothing presented that gives us a better understanding of noise, how it affects AC power cables, and more importantly how it can improve the sound of audio signals. At the end of the day this is clear snake oil.

In many ways I admire what Amir tries to do but he seems a measurement fundamentalist. Measure AND listen

What speakers are those!?

Delusions are very powerful things. And as for the flat earth earth analogy, it's a metaphor appropriate to your attitude, not your critics. The burden of proof is on you. Barbara Streisand sends her best wishes.

Where are the DATA?

This is old so I doubt anyone reads this, but I believe Danny, but I believe you have to put it in context. I do not think a lot of these things matter on 95% of systems, I’m sure if you have a system that costs 50 grand or more, then maybe your cables can make a tangible difference, but on most systems it’s irrelevant.

You guys should get a room already

That convoluted urethane foam on the walls as “room treatment” is amusing.

I honestly thing that that Samir chap has had a lot of issues at kindergarten and that his AP magic box is his way of dealing with it...
