Premium Power Cable Survey: The Results Are IN


Survey says ....

Thanks to the 179 who took the time to complete the One Minute (okay, TWO minute) Survey. If one thing was clear to me after designing the survey and collecting results is that this is one elite group, with a collection some of the most NOTE-worthy music systems on the planet.

It was no surprise that not everyone shares the same opinion on this subject. There are those who feel premium power cables were on the order of magnitude of migrating prerecorded music from the cylinder to the disc. And, others who feel that premium power cords are the industry equilivent of Pinto exploding gas tanks.

Rather than a plea for decorum, which has been done before (not always with the best outcomes), I’d like to request sometihing a little different. A request that we minimize our energy and emotion related to the specific subject matter at hand, make it somewhat generic, and encorporate "newer thinking" where we maximize the benefit of our time shared together on these forums. Particularly on subjects where we disagree. It’s been said: "It’s better to invite someone tell you what’s right about their viewpoint than to tell them what’s wrong with it."

I’d like to begin with the premise that those who contribute here feel they have something to say. Sure there are "opinions" and "rebuttals" that may be entertaining, but we have the most to gain when contributions add something of value to others in the group. The "best of the best" are actionable items where the reader not only has something to learn, but is compelled to take some action to improve the performance of their systems.

As mentioned earlier, this is an elite group of audio enthusiasts. Some of the best ears in high performance audio, with the brain matter to go along with them. I’d like to suggest that those claim who "hear" sonic differences actually DO hear them. And, those who don’t hear something magical happening, actually NO NOT hear it. The correct response in my view is not to immediately challenge the person and their perspective, but rather ask the question: "What are they hearing that I’m not hearing, and why am I not hearing it?" Or, the inverse. Assuming BOTH questions are valid, then take the conversation to another level. "Tell me about your system. Your location. Your room." The ideal scenario would be to place yourself IN the environment in question to listen for yourself. You may find that you heard nothing of interest. Or, you may find the person did, in fact, hear something pretty amazing. In most cases, the logistics will prevent this from happening. So, we can only share our viewpoints, among gentlemen that we share indulgences with and hopefully those receiving our communications are willing to allow us to tell them what we feel is right about our experiences.

That being said, there are those on the survey with a very high degree of certainty that their observations were correct. Some on the positive side. And, some on the negative side. Hopefully, we can upgrade the conversation from "disbelief and delusion" to "curiosity and willingness to experiment." I hope we learn more about ourselves from the survey and find even more ways to connect in a positive way.

Thanks for all who contributed.

A little "housekeeping issue". The "dashboard" link below will take you to the results of the survey. The couldn’t figure out how to edit the font size, so some of the text is crammed together. I hope there is enough information there to make it discernable.

No

Thank you again for designing this survey. The results are helpful to me in better understanding the values of the community, of which many I share!

The ? How much is enough to spend ? Digital very important 

then everything else $1k say a AQ Thunder that’s $4k just for 4 power cords 

then the $$ Ethernet cables, usb cables  which can be reasonably $4k for 3 cables

For linear  power supplies my max is under $300for  each power cord ,

interconnects, and Loudspeaker cables how much are you will to spend 

I have seen $50k just for these cables ,Which I could never afford .

the list and ? Questions go on .

 

@acman3 @blisshifi You're welcome.  Glad you found it to be of value to you.

@audphile1 I think surveys can be of value to the group. Maybe a survey to determine top areas of interest.  Then, a pre-survey to determine most relevant questions.  1 survey was enough for me.  Volunteers?

Post removed 

@waytoomuchstuff I’ll be happy to take it on. I’m preparing a lot for AXPONA but perhaps I can get an initial thread out by tomorrow night with some thoughts on future surveys and see what people might be most curious about.

For me, beyond types of cables and gear, I will be interested to know more about peoples’ listening behaviors, consideration and purchase behaviors, and what their “real life” audiophile communities look like. 

If it's based on listening when the person knew the brand and cost of the cable, (in other words, not objective) your survey is pointless. But if that's how you want to spend your time, so be it.

Thank you for coming up with the survey.  To the results, I was a little surprised at how many are multiple generations in, like upgrading the upgrade, and at how few have DIY’ed.

+1 @mrskeptic 

The survey was of OPINIONS.  Not hearing.  It has no value.  Only double-blind tests have value.  Hearing is not purely a mechanical process.  Unfortunately there is your brain between the sound and what you hear.

@mrskeptic 

"If it's based on listening when the person knew the brand and cost of the cable, (in other words, not objective) your survey is pointless. But if that's how you want to spend your time, so be it."

You have named yourself well. Almost as if you knew your response before you started.

Not sure why you want to trash someone that did something to try to help people on this site.

Just because the questionnaire isn't perfect is no reason to be so negative, "Mr. Skeptic".

 

@waytoomuchstuff 

Thanks for doing the survey.

Always interesting to see how other people approach sound quality and equipment.

 

 

 

In a blind A/B/X test, conducted by Keith Herron, it was determined and RESULTS REPEATED that a 3 MILLIBEL difference in tonal response was consistently detectible. With that in mind, it’s quite conceivable that minor power supply differences, including input cables, can make a difference in tone qualities and performances.

I was involved in the test and the difference was not as subtle as one might suggest.  

 

The survey was of OPINIONS.  Not hearing.  It has no value ...

This is a hobbyist's group that is full of opinions. If opinions have no value to you, what are you doing here?

@waytoomuchstuff, Thanks for the time and effort that went into this task, always fun to read what others have and think.

@clearthinker If we all took the same Hearing Test, do you think we would all have the same exact results? I don't because everyone's hearing is not the same.

An interesting survey, which presents interesting facts about the perceptions and interpretations of the group. Which of those perceptions/interpretations map onto reproducible sonic realities is impossible to determine, but as Mulder liked to say, "The truth is out there."

@cleeds    My statement was too broad.  I should have said that the survey has no value as a determinant of whether changing power cords can make a difference to sound.  It does have value as an exposition of peoples' opinions.

@brianh61   I agree with you.  But the purpose of a blind test is to determine whether one individual can hear differences with his hearing.

@waytoomuchstuff   "I’d like to suggest that those claim who "hear" sonic differences actually DO hear them."     I note your careful use of inverted commas for "hear".  It may then be that you agree with the rest of my statement below.  I don't claim such people do not perceive a difference.  It is just that their perception is equal to the sound emanating from the speakers PLUS the modification applied by the conscious and sub-conscious brain.  So it is not possible to determine if changing power cords can really make a difference to the sound - ie that emanating from the speakers.

I don’t believe this survey was ever intended to prove whether power cables change or improve the quality of sound, but to share the opinions and trends of the community. Part of any community is a sense of belonging based on shared value, and opinion goes a long way in feeling that value. So let’s not rip each other apart over something it was not intended to be and allow for a this community to thrive in a positive way. 

Interesting survey. I did not take it since I built my own cables a couple of years back. I was able to make custom lengths to my power controller. I used quality components from Furutech. It was a fun project. 

... the purpose of a blind test is to determine whether one individual can hear differences with his hearing ...

That is a misnomer. Yes, you could conduct a blind test with a single listener, but it would only yield a single data point. Most researchers who conduct ABX listening tests - I’m talking about people like Toole and the folks at Harmon - conduct tests with panels of listeners. That’s because the ABX test wasn’t designed as a hearing test, but as a protocol to test devices: the Device Under Test. If you want to test a listener’s hearing, that’s a job for an audiologist.

I’ve noticed on A’gon that the purpose and value of blind testing is often misunderstood or, perhaps, deliberately twisted. In any event, lacking one should never be used to bludgeon those who have no use for them, which includes many of us here. And remember: an improperly conducted blind test offers no added value over sighted listening.

 

So let’s not rip each other apart over something it was not intended to be and allow for a this community to thrive in a positive way. 

+1.

@waytoomuchstuff Thanks so much. Now I know where I am on the scale of audiphiles🤣. 

and for the community in general, personally I try to abide by the posit: "who's crazier, the crazy person? or the person arguing with the crazy person?" I have a lot less arguments when asking myself this question.

@waytoomuchstuff  - Txs for the effort. Ignore those taking potshots

@blisshifi I'd be interested in participating in any of these surveys you proposed

"I will be interested to know more about peoples’ listening behaviors, consideration and purchase behaviors, and what their “real life” audiophile communities look like."

the survey has no value as a determinant of whether changing power cords can make a difference to sound.

That's overstated, in my opinion. There are a sufficient number of reasonable and intelligent people testifying to hearing something that even with all the variables involved, there should be a high confidence that changing power cords can "make a difference" to sound. "Make a difference" is a very low bar, of course.

I don’t believe this survey was ever intended to prove whether power cables change or improve the quality of sound, but to share the opinions and trends of the community.

Surely, that's too wan a statement. Share opinions and trends? About what? About cables and whether they can change or improve sound. Otherwise, are we just opining for the sake of opining?

The survey was about something and it showed something. It is not precise about what it shows or how much, but it's a start. 

 

 

Interesting.  Lots of work !!  Thanks.

I would want to know the technical background/engineering degrees/# of power systems design type info.  And certainly whether it was blind testing.

There are a sufficient number of reasonable and intelligent people testifying to hearing something that even with all the variables involved, there should be a high confidence that changing power cords can "make a difference" to sound.

That's very well stated. Unfortunately, there are those that simply dismiss all the empirical evidence, as this thread reveals.

I’m tired of all the arguing, debating, and whining on here. 

So, leave.

Dang! I thought I was the one that got under people's skin. Premium power cables get the same consideration as the rest of our system. We purchase the best equipment we feel is appropriate for our budget and our system. Some are satisfied with what is supplied and some want to chase perfection. There really is no right or wrong. Only what is best for you. I'm not going to chastise anyone for their opinion. I personally have two higher end cables. I will purchase more as I am able. In the meantime kick back and enjoy your efforts.

This is a hobbyist's group that is full of opinions. If opinions have no value to you, what are you doing here?

 

@cleeds :  +1.

 

Also:

That’s because the ABX test wasn’t designed as a hearing test, but as a protocol to test devices: the Device Under Test. If you want to test a listener’s hearing, that’s a job for an audiologist.

 

Couldn’t have said it better. +1000. That’s a key fact the ASR crowd of the “clear thinkers “ don’t get. Either by ignorance (best case scenario) or simply on purpose 

In the meantime kick back and enjoy your efforts.

@parnelligq : exactly! This is a hobby. Not a competition or Cin Dyment / ASR challenge. 

Thanks for the effort - interesting results.

My responses were closer to the majority or 2nd ranking more so than I expected. I.e., I don't have a higher-end PC for every component nor have I spent a fortune.

Great results from a great survey. Nice to know I think and hear like the majority who honestly responded to the survey enforcing the notion that it's not casual in the least and therefore not so easy to dismiss out of hand, unless you're a nag. 

All the best,
Nonoise

The survey was embedded with a lot of data.  Unfortunately, these details are not easy to share.

Here's an item of interest:

Of the 32 responses who indicated low, or very low expectations (negative bias) related to premuim power cables

12 heard no difference.

19 heard "significant" or "awesome" results.  2 heard "good" results

Of the "heard no difference" group, 3 indicated they didn't listen.  2 of those listened to only 1 system, and 4 were "not sure, could have gone either way" in their findings.

Not trying to bend the results in any particular direction.  Just sharing what the survey showed.

Years ago I had some Stax headphones and their matching amp. I bought some kind of expensive power cord for it. I honestly couldn't detect any change in the sound. I tried really hard to hear something but didn't get even the subtlest of impressions of a difference.  It could be that that Stax and some other speaker amps I used it with later just didn't need whatever that cord was doing, or it wasn't the right power cord that would have helped them in some way.  I liked the look and feel of the power cord. It was definitely better built than anything I'd had before and it inspired confidence. One downside with it was that it was so thick and stiff it could push whatever it was plugged into around, making it difficult to put devices just where I wanted without them being pushed sideways. 

In contrast to the power cord, I really did perceive what I felt was a very significant difference when using some expensive silver interconnect cables. That difference completely disappeared when I did a blind comparison to some super cheap cables. I don't know if this happens to everyone buy my hearing perception changes a lot from day to day, and sometimes over the course of just a few minutes. I've done listening comparisons where I've heard something really good from one component, then switching to the other component the sound has seriously degraded. So I go back to the first component but the sound remains seriously degraded. This used to happen to me when I played string bass too. The instrument would sound rich and warm and then start to sound really edgy and raspy. I really think it was just me and my unstable perception of sound quality. My ear's sensitivity to different frequency ranges changes, and this can be because of psychosomatic effects or just purely physical processes. My sinuses seem to be in a constant state of flux, as is my hearing.

@waytoomuchstuff 

thanks for entertainment! 

it will be good to see what exact power cable ppl replaced with “good one”! 

I have no doubt that I would fail a blind listening test with A versus B power chords. Having said that, I did spend what I consider to be real money ($200-$300 per chord) to purchase entry-level "premium" power chords. They look good, and fit well, and I am satisfied that I didn't skimp entirely, given that my overall system cost is around $35k.

"Other" responses to the question: "If you have NOT purchased a premium power cable, what is holding you back?

"The Romex in my walls, as well as the miles of wire to the power station, are not premium."

" make my own. I borrowed Nordost Tyr 2 power cords and they made the whole system VERY diffuse and lost bass. I tried it on my audiomagic conditioner, my integrated amp and my dac. Same result to varying levels."

"Being an electrical engineer I know better. The only benefit the larger/better power cables have are the ability to handle higher current and voltage loads....NOTHING MORE."

"All showed 0 significance"

"Just do not know / not convinced which one to buy"

"I tried them and they didn’t work"

"Isolation transformers do the same job, but better. I use three."

"other methods of mitigating high frequency noise"

"Premium power cords are part of the basic tool set of the audiophile, without them you will not be able to reach the potential of your system"

Thanks to those who took the time to provide a detailed response to the question.

@willyht

You are not alone. There were more than one respondent who owns premium PCs and not convinced they make a difference. I can appreciate your answer. It might have been an interesting question to find out why people added premium PCs to their systems given no perceivable sonic benefit in their view.

Since you’ve had time to listen to your system for an expended period of time with the premium PCs installed, it might be an interesting experiment to revert back to the OEM cords and listen again? Might be a fun way to spend an afternoon/evening?

My comment was intended for the member whose comment was evidently deleted, just another tedious cable denier. 

@waltersalas 

Looks like I missed something "interesting" with the deleted post.  Guess I need to check for comments more often.

Very nice system by the way.  Haven't heard the Fynes, but the "speaker geek" in me was doing cartwheels.  They're probably not shy about presenting a lot of musical energy (and, detail) into the room?

@waytoomuchstuff 

 

Thanks, kindly. Your post reminded me I need to make some changes in my system profile, but the Fynes are still here and they are indeed quite excellent, as well as being efficient and very "amp friendly." I've heard some great solid state amps on them, but really do prefer them with tubes. Try to hear a pair if you can. I flew to Florida to audition the 704s, and within two hours, I was writing a check.
