hi-end a/c pwr cords ABX blind test results

[Fleaman]

the test

Blind ABX testing on hi end a/c power cords! I doubt this will change the minds of the faithful (those faithful to the hi-end a/c cords), but this is a pretty thorough test and this site happens to be one of the best, least biased out there...even though they are a consumer audio/video site.

"Using the blind ABX protocol, we failed to hear any differences between an assortment of generic power cords and Nordost Valhalla. Therefore, we cannot conclude that different power cords produce a difference using the blind ABX protocol. However, we also cannot conclude that there are no differences. We simply failed to prove that differences can be detected to a statistically significant degree using a blind ABX protocol."

This one's for you dj!!!!!

What piece of equipment would you be speaking of?

Power amp?
Board supplies?

??

Where would one care to employ a high end cord..if at all?

All that and more level !

i believe if you connect your equipment with wires thin as a hair there probably would be loss in audioquality if the capacitors or voltage stabilisation of the power supply in your gear is build too flimsy.

but in all other cases dfegad "high end power cables" ----> brainless amentia

To be honest this test is bunk...so the deliberations must continue.

Why? Or more importantly, what kind of test would be de-bunkable?

Like I mentioned, to some of the faithful, nothing, no kind of test, no kind of result, even if they were one of the testers in a double blind test, could convince them there wasn't something worth the $$$ to spend on such a cable. It would be like trying to convince a born again there is no god or a atheist there is.

It's true that there wasn't instant switching between cables and therefore the time lag became a factor. But hey, those out there claiming noticeable differences didn't have the capability of quick switch either.

so isn´t this test silly?

BTW do you believe in sound quality enhancement by power cords?

Not if the generic pwr cord is of the proper gauge.

And as far as the test being silly, well, I'd submit that $2,500+ pwr cords are silly, even $100 pwr cords. I'd rather spend the $100 on a good line conditioner.

If people weren't paying hundreds and thousands on pwr cords (I guess they must be?), then it would of never got to the point of having such a silly test.

Again, all those that I have read were claiming improvements with hi-end a/c cords were not switching between cords quickly either, if anything, in this a/b/x test they reduced the time between cords greatly, a lot shorter than say 'dot's cord switch time period.

If you were in the studio by yourself, how long would it take you to get out of your sweet spot, pwr off, change cords, pwr on, go back to sweet spot, etc.?

My point being is that if this a/b/x/ test is bunk to you, then you would also have to consider a single persons cord tryout bunk too.

At least I would. But hey, I'm not that faithful of a guy, I lean to the science end of things.

Record the results.

Or that!

I suppose there is no reason that if pwr cords had an effect on amps/pwr'd speakers, that they shouldn't have an effect on consoles, rack equip, recorders, etc.

Yeah, record the differences!

Does a designer of gear... say a Rupert Neve, a Dave Derr, Dave Hill, etc., design his gear using a "high end" power cord, and then go....

"You know, I am going to use this inferior cord when I sell my products"?

Or is it more likely that the piece of gear was designed and "voiced" to work within the specs that the power cable they provide gives?

And what type of wire comes from your breaker box, to the plug? Could using a "high end" cable for the last 3 feet make a difference?

I think not.

Of course, if I was getting a bunch of free gear, or had the offer of getting paid to come online and tout somebody's power cords, it would be a hard decision.

If it looks like a duck, walks like a duck, and quacks like a duck....

I don't lose respect for those that wear their affiliations on their sleeve, but those who defy all logic to "endorse" products strike me as suspicious. There is a big difference between a "gear pimp", and a "gear wh0re".

I'm still waiting for the AC Cable Listening Sessions... where do I send the money?

And how did the power get from the generater to that breaker box? Again, hard to imagine what difference that last 3 feet could make.

[kevinc]

You could.....

1. Get 2 dangerous 2 busses.

2. Set one up with a Requisite cable and one with a Radio Shack cheap as possible cable.

3. Send an identical mix through both 2 busses from the same source with the same converters.

4. Send the 2 mixes to a mastering console or some other box that you can A/B things quickly with a button.

5. Ban me from this forum for again contributing to an AC cable thread in a serious manner.

If theres any "blooming" going on from the good cable it should make the Dangerous 2 Buss "come alive" while the bad energy coming from the from the "Shack" 2 buss should sound inferior.

kevC,

That only works if you place your gear on top of those little stone cones, to isolate bad vibrations. If you don't do that, it negates the quantum benefits of the flux capacitor.

True. But they only work if the tin foil on your head is genuine Reynolds Wrap!!!!!

And more important still is to polarise your water supply as H2O polarity variations in the pipe flow in your walls can be detrimental to certain types of sensitive audio equipment.

Yeah, that is the only way to get the full quality sound out of your Studio Projects microphone setup.

true. but you can install a vortex filter into high performance twisted pair water pipes to twirl the polarity. so no static polarity will occur any more and thus your audio eyuipment can´t be infected by evil interferences. it´s the same infamous princip as balanced audio wiring.

i´ve read a lot of test and all of the highest expirienced tester were amazed!

[kevinc]

I prefer the carbon fiber cones under my speakers for maximum lightweight stiffness.

Same for under the Dangerous 2 only those must be teflon coated so the bad energy just slides right off em`.

[hollywood_steve]

If you don't do that, it negates the quantum benefits of the flux capacitor.

You will be receiving a bill from my local laundry. While I have spewed various liquids out my nose on prior occasions, this was the first time I managed to get dry bits of a cookie to come flying out. Curse you!

(as an explanation, I worked on several various BTTF tie-ins at Universal and since then, any use of the term "flux capacitor" causes instant loss of composure)

You don't need one. Just buy a ticket to Bangkok.

What we are saying is that if you were to spend $6000 sending your rack to Thailand, you would need 86,367,451^10 instances of $300 AC Power cables in order to hear the ambient sounds of a Bangkok 'Tea-House' from way out in Space with <0.000000000001 slew & distortion...

No, wait.. darn.. what was the question?
