New expensive power cord for amp and no change in sound?

"Why do you guys care?” .to share our own mistakes and best methods, is it wrong? 

Why do you guys care? If you believe that most of this stuff is snake oil then dont buy it. There always seems to be an undercurrent of smugness when you guys discuss how others spend their money in ways you deem inappropriate. I dont understand the thought process or the motivation. Seems like a circle jerk to me, albeit one with no clear purpose.

 

 

Expensive Cables, Wires, and Power Cords to make a huge difference on your wallet and that can affect your listening experience. Because you spent so much money you're going to hear things you never heard before. Like your brain telling you you should have never spent that much money on snake oil.

 

Very true!

Paul McGowen frequently uses the phrase snake oil. And he's a major seller of such.

That's why I don't watch his channel anymore and it (selling snake oil power cables conditioners) affects sales negatively.

 

Change the wall socket next. That should do it.

Not disclosing brand names is ridiculous. Brand pairing has been discussed a million times.

"Paul McGowen frequently uses the phrase snake oil. And he's a major seller of such."

- So maybe "snake oil" is good  😀

Because you spent so much money you're going to hear things you never heard before. Like your brain telling you you should have never spent that much money on snake oil. Joke joke joke. I don't put a lot of stock in it. I bought some great wires and cables etc and I've had some really cheap ones.. The problem with the cheap ones is the build quality. Of course you never go for the cheapest stuff ever. Put yourself a reasonable spending limit on them and spend within your budget. I mean you should really consider it when you're buying a system that you know you're going to need cables, wires and etc etc. These are just accessories and there's a difference between the good and the bed and the ugly. The good is half decent Brands at good price. The bad is the Rock bottom cheap ones that don't have the best wiring or connections. The ugly is the overpriced ones that try to sell you something that is snake oil. Be a smart, educated buyer. Just cuz you're eating a steak. Doesn't mean you need a gold fork.

 

Take your coomon sense and get out!

Use a gold fork if it makes the steak taste better. 

I will give you a hint, dont use words like "snake oil". Defines your tribe and taints everything to follow.

I didn’t read all the post so if someone mentioned this. You stated in first post “after a couple weeks of daily use I hear no difference”. Does daily use mean you are not running cord 24/7? Even if you are running amp 24/7 300 hours may not be enough to burn in your cable. If it’s not run in it will sound thin. 

""Have you tried an after market cord?”

- Yes many times, the first one about 25 years ago.

"why?"

- I was curious about the products and most units came with detachable cords to make it easy to do so.

@phd "Power cords can make a huge difference. This difference can be on par with buying a new amp (component upgrade).” (-) in your bank account!

@dill "Have you tried an after market cord?” why?

@mapman +1M! the best comment ever! "The there is always the option of changing the amp. That will surely change the sound of the power cord"

@dentdog 

 

👍

@dentdog -

       KUDOS, to another experimenter, for trusting their ears and senses!

                                          Rewarding, isn't it?

                                 Enjoy your systems and music!

I've read this thread and each poster has his/her reasons for buying in or not on the power cables. JMO but had an experience that confirmed for me, in my system, that they do matter. 

Purchased some speakers, Evolution MM3s. Decided to get the Evolution power cords for the powered woofers. You know, recommended kit yada, yada. Had some Fusion Enchanters for my Monoblocks, ribbons. Well the Evolutions were 6' and the Fusions 5'. Basically had to switch as the run to the speakers was easily reached with the Fusions cords and needed the longer cables to reach the amps. So I flipped them. Significant difference. Didn't expect it, didn't want it to be so. Therefore no expectation bias. The difference was as plain as day.

@ps-

      KUDOS, for experimenting with your system's sound/trusting your ears & senses.

      Supra follows some of the same basic science/construction as I've mentioned, if you've read their explanation, as to why their PCs sound better* than stock/common wire.

 cables that, from my perspective, are priced absurdly high, make no sense.

                                                      I agree.  

       However: those more comfortably situated than I, with much higher end systems and larger/better listening environs, can afford and demand the very best the likes of Kimber, Analysis Plus and Synergistic have to offer.

                                                      I would.

*https://www.madisoundspeakerstore.com/wire/cble/supra-lo-rad-power-cable-cs-us/

@rodman99999

....or the hyperbolic pontificators? :)

Full disclosure, I make my own power cords using Supra wire and their connectors.  These are relatively inexpensive and they certainly do a fine job whether the component is tube or solid-state. And while I've experienced merelt changes or an occasional "improvement" in SQ from wire to wire, cables that, from my perspective, are priced absurdly high, make no sense.

The purveyors of those high-priced wires will, of course, disagree.

 

 

@ps-

"Unless there was something very wrong with your last power cord, or it was just a very poorly made one, you’re not going to here any differences other than those that occur within your own mind via confirmation bias."

- prove it

The scientific methodology that can found/support/refute theories works on disproof via hypothesis testing. Science doesn’t prove anything. Very common misunderstanding.

The crux of this thread’s OP is that an expensive power cord was compared to a more expensive power cord (albeit with the usual flaws that make an uncontrolled design) and no difference was detected. That is, quite literally, hypothesis testing for difference, and @roxy1927 failed to reject the null (Ho = no difference).*

I understand why the deterministic claim of another poster you quoted might have bothered you, @dill - fine. But instead of picking at someone for typographical errors or for stating a strongly-toned difference of opinion, consider further study on how experimentation works. The info is out there and free. 😉

This thread posed something different from the paradigms of increasing sonic returns for money spent and being able to count on improvements using one’s own hearing (maybe). But it’s one uncontrolled (sighted, ill-timed, etc.) design that merely supports a camp of cables-can’t-be-audibly-different by way of failing to reject a null.
No big deal, really. If everyone chats about their experiences but no one’s controlling for their biases or setup, then it’s all different variants of apples and oranges - nothing that comparable when everything is confounded by incongruous variables, hey?

*in hypothesis testing, the investigator(s) will not “accept” a hypothesis any more than they’ll prove something. They reject, or fail to reject. That may look like semantics in print, but it’s a very important discrepancy in practice.

Which came first, the rabbit or the hole?

No one can tell you whether/how your system, room and/or ears will respond to some new addition.   There are simply too many variables.      LIKEWISE: no one can possibly know whether a new addition (ie: some kind of disc, crystal, fuse, interconnect, speaker cable, etc)  will make a difference, in their system and room, with their media and to their ears, without trying them for themselves.         Some companies offer a 30 Day Satisfaction Guarantee, so- those that are actually interested, have absolutely nothing to lose by trying (experimenting with) such.           Anyone that knows anything about the sciences, realizes that something like 96% of what makes up this universe, remains a mystery.             For centuries; humanity’s seen, heard, felt and otherwise witnessed phenomena, that none of the best minds could explain, UNTIL they developed a science or measurement, that could explain it.           The Naysayer Church wants you to trust their antiquated science (1800’s electrical theory) and faith-based, religious doctrine, BLINDLY (their credo: "Trust ME!").       Theories have never proven or disproven anything.  It’s INVARIABLY testing and experimentation that proves or disproves theories/hypotheses.         IF you’re interested in the possibility of improving your system’s presentation, have a shred of confidence in your capacity for perceiving reality and trust your own senses: actually TRY whatever whets your aural appetite, FOR YOURSELF.                                The Naysayer Church HATES it, when THAT happens!

@wesheadley  (et al)= Nothing but further Dunning-Kruger runway builders.

                  Worthy of nothing but a short snort of derision and being disregarded.

             Give their ilk an opportunity at a bit of education and they respond with the same old primitive drumbeats.   

                            Like trying to teach a box of rocks to sort your socks!   

                                                                     😏

"@dill - Shouldn’t you want to "prove it"?"

- I have proved it to myself, the only one I need to.

"Beyond a certain level of build or materials quality, more money gets you nothing"

- yea, you need to believe that to validate your position.

often, if it sounds "different" it will sound better to some and not to others...and yes, many here have done blind tests, but to decide for ourselves, no need to "prove" to others...no one here really wants to spend money and get nothing in return...though some seem to think many here do and are not able to make reasonable decisions for themselves...

@dill - Shouldn’t you want to "prove it"? What experiment or test do you propose that will allow for a fair evaluation? There’s no "better", there’s just different. Beyond a certain level of build or materials quality, more money gets you nothing except that warm and cozy feeling of certainty that comes with confirmation bias. Take away the labels, do a blind test, and you will never be able to discern good, better, or best. To paraphrase Pete Townsend, "Is it in my head?". You bet it is.

Quick overview of my experience:

►Definite improvement from $10 stock cord to $100 level after market cord on every component. Usually heard in elimination of background ’noise’. or just improved power delivery

►Once a system is built that is close to one’s ideal (say a 7-8 out of 10), then power cords can make another medium/large step toward that ideal (to reach that 8.5-9 out of ten level). At times, I’ve noticed connectors can contribute significantly (almost as much as the cable) in some cords (think Furutech, Oyaide, etc.)

►Cable size, geometry, materials (copper, silver, carbon, air dialectric), and cryogenic or ’cooking’ treatment can definitely contribute to achieving that ’last mile or two’ of performance/preference.

► After starting with Bob Crump’s (TG Audio) cords over 25 years ago, I’ve probably tried 30-40 different power cords over the years, with mixed results. I’m currently using a large diameter silver power cord (Tek-Line) on an amp, smaller diameter diameter cord on transport (Acrolink 7N4020III w/Oyaide 004 connectors), and Argento Flow Master on DAC. Electraglide or other ribbon cord(s) on things tubed, especially preamp. YMMV.

►Like most of us, I have quite the collection of power cords, interconnects, speaker cables in the [big] boxes in the closet. And I must say, most I actually liked at the time; just moved on to 'better(?)' 😊

"Unless there was something very wrong with your last power cord, or it was just a very poorly made one, you're not going to here any differences other than those that occur within your own mind via confirmation bias."

@wesheadley -

                                               And (again):

          Anyone that feels compelled to harp on not hearing any differences, is obviously too obtuse to understand the term "variables" (as frequently mentioned) and worthy of disregard. 

 The claims made by so many ultra-high-end cable companies are pure sci-fi fantasy-- and they have the non-science to back them up! Just go for quality made cables that use quality materials, especially the connectors, and you'll be fine. Don't drive yourself mad buying into voodoo claims made by companies that make obscene profits by trying to differentiate their products with sci-fi lullabies. 

       Another rerun, since so many of you are a waste of keystrokes:

Cargo cult science is a pseudoscientific method of research that favors evidence that confirms an assumed hypothesis. In contrast with the scientific method, there is no vigorous effort to disprove or delimit the hypothesis. The term cargo cult science was first used by physicist Richard Feynman during his 1974 commencement address at the California Institute of Technology.[1]

Cargo cults are religious practices that have appeared in many traditional tribal societies in the wake of interaction with technologically advanced cultures.

     Do a bit of research and you'll learn those primitives were limited in their understanding of what they saw with their eyes, based on their prior experience, education and BIASES.

                                                A rewind:

                 It isn't that the Denyin'tologists are ignorant.

               It's they're knowing* so much, that's WRONG.

                       *heart of the Dunning-Kruger Effect

                                              OR, two:

     The Church of the Naysayer Doctrine (like every other faith-based, religious cult) has as many dopes as it does Popes.   

     Bring up anything resembling SCIENCE/PHYSICS, dated later than the 1800’s and they become apoplectic, not having the formal education to comprehend the concepts, or- possible ramifications.    THAT would be hilarious, were it not so pathetic!        

           Gimme That Old Time Religion, Gimme That Old Time Religion, etc.

        At the very first mention of something as simple as Wave Function (a BASIC tenet of Quantum Mechanics), the Cargo Cult will label you a KOOK.

        But remember: they can only view/understand you, based on their limited experience, education and BIASES.

         They have overlooked the fact that, if not for the hypotheses/theories and experimentation, regarding Quantum Mechanics: a plethora of modern conveniences, medical devices and the gear they so love, would not exist.

          Had scientists, chemists and inventors shared the doctrines of the Cargo Cult (Denyin'tologists), there would be no semiconductors, computer chips, LASERs, or Magnetic Resonance Imaging devices (MRIs).

                                         Solid State amps?

                                     OOPS (back to tubes)!

                                        Your Smart Phone?

                                        FA'GET ABOUT IT!

                                         Your car's GPS?

                                                NOPE!

    Then too: some may be willfully ignorant and just enjoy being contentious.

                        Others: obtuse, uneducated*, misinformed?

      *Typically, from what's been exhibited here: H.S. STEM, if that, would be a safe inference.

      Either way: the result, when the Cult begins its rhetoric, is a classic demo of the Dunning- Kruger Effect.

                                          But, I digress: 

       Bring up those pesky details, regarding the likes of QED, Dielectric Absorption, Poynting's theorem and possible application/effects, relative to frequency, that our musical signals are carried via photon or wave, outside the conductor and you're a KOOK?

         Again: the Cargo Cult can only understand anyone with an actual background, experience and education in Physics/QED, based on THEIR own beliefs, education, experience and biases

                                      Remember this?.

     One anecdote  that some may find interesting: their walks in the woods and how his father would encourage him to look beyond the fact that something in nature exists, into why and how.

     It saddened him that while attending college, during a visit home and one of their walks: his dad asked what he was learning in college.

     At that moment, Feynman realized: if he tried to explain what he was learning, there was no way his dad could understand.                               

                            It wasn't an insult or condescension.

                                                Just reality.

                                    Oh well: let 'em go build a runway!

Unless there was something very wrong with your last power cord, or it was just a very poorly made one, you're not going to here any differences other than those that occur within your own mind via confirmation bias. This has been tested to death. BTW, no one will ever be able to rank a set of well made power cords by quality based upon what they cost. So spending stupid money on cords would be far better spent on room treatments or better gear IMO. I liken these kinds of gimmicks to the nutraceutical industries claims about their pills and potions-- they (almost) never EVER stand up to any kind of real scientific inquiry. The placebo effect however is very real and in almost all cases, the products never test better than the placebo control group. The claims made by so many ultra-high-end cable companies are pure sci-fi fantasy-- and they have the non-science to back them up! Just go for quality made cables that use quality materials, especially the connectors, and you'll be fine. Don't drive yourself mad buying into voodoo claims made by companies that make obscene profits by trying to differentiate their products with sci-fi lullabies. 

Not buying it. The voltage drop across a few feet of power cable can't be more than a volt. This is insignificant compared to the normal variability of the supply fluctuations between 114 and 126 VAC.

@noromance I've measured over 2 Volts, but that was on a class A triode amp that made 140 Watts... or it did if the AC was right. When the spec line Voltage was at 120V the amp only made 100 Watts. The measured AC line Voltage at the IEC connection was closer to 117V as opposed to the Voltage at the outlet. A 40 Watt loss is not only very measurable but also audible.

As I said earlier, the power draw from the line is an important aspect of what you can hear and measure. Internal power supply regulation as well as feedback to allow the amp (or preamp) to reject effects of AC line Voltage have an effect as well. So some people will hear things and others will not.

This also explains why many people report better sound at night (which the AC line Voltage tends to be higher).

Trust your ears. There are many PC review videos. Don’t trust reviewer’s ears. Listen to the recording of the actual PC. Comparison videos are better. Microphones don’t lie. Human ears are biased always and they trick us. If I like A sound better than B sound in a comparison video, I like A sound better in real life too. Alex/WTA

@rodman99999 

+1.

@zlone Depends on how your system is balanced (lean, warm, bright?), sound characteristics you’re looking for and budget. Not to high jack this thread, may be start a new discussion? Or pm me. 

Should have called the cable company.    Try before you buy!

                                              EXACTLY!

        There are also a number of other cable manufacturers and purveyors that allow a listening period and return policy, if you are dissatisfied/unimpressed. 
         ie:  Synergistic Research has offered a liberal audition period since the early Eighties.      Matter of fact: they offered to send their entire line of interconnects, for one to audition/experiment with, before they made their choice and purchase decision.

                                               And (again):

          Anyone that feels compelled to harp on not hearing any differences, is obviously too obtuse to understand the term "variables" (as frequently mentioned) and worthy of disregard.  

          My only goal in these threads has ever been to encourage those with a mind to experiment with their systems, based on the latest (20th/21st Century's) findings of ACTUAL Physics/science and ignore the Cargo Cult's incessant runway building (objections, convolutions, deflections and obfuscations).

                                                Happy listening!

@audphile1 I had a Pass XP-12 preamp and now running XP-22. Power cords make a difference on these preamps as well. 

I am about to start breaking in a new XP-12 and I will start with the stock cord, can you recommend some cords I should consider if I choose to upgrade?

should called the cable company, try before you buy !

@roxy1927

I have several Shunyata products in my system and every one of them works as claimed by the manufacturer at every price level. You would do well staying with Shunyata. The difference in SQ will be appreciated more and more as the power cord breaks in. May be subtle at first but after 400 hours, switch out the new for the old and you will be very pleasantly surprised. Enjoy!

Are you guys even paying attention??!

He bought a several thousand dollar power cord to replace a $500 dollar one and heard no difference between the two. That is the premise of the thread, NOT he bought a $500 power cord and heard no difference between that and a stock one.

All this demonstrates is that you are a sensible person who doesn’t automatically assume that because he paid $500 for a power cord it sounds better. Congratulations on having such good sense. The power cord mania is pure nonsense. I bought fancy power cords for all my components a few years ago and ended up selling them all because they made no difference in sound. They looked great, but I wasn’t about to turn my units backwards so I could admire them.

@squared80 this is not entirely true. First, often supplied power cables are poor quality. Cost cutting. Pass cables are pretty good actually, properly designed. Hospitals use medical grade connectors - so they care about better power connection, right?

There is indeed a LOT of snake oil. But there are also poorly designed power supplies…

Nelson has an excellent writing on how much Class A amp must weigh. And if weigh less, you are getting scammed. Because amo must have proper power transformers and headsinks and they weigh a lot.

@squared80  (et al)-

Enjoy your snake oil. Anyone who says high priced power cords or speaker wire changes the sound is lying, ignorant, or a victim of confirmation bias.

                                                Just reality.

                                    Oh well: let 'em go build a runway!

           Einstein got that last one wrong (Quantum Entanglement), BUT- I still wish he'd been alive, when the Hubble Telescope proved, what he considered his, "greatest blunder" (his inability to bring symmetry to his field equation, without lambda).

Another example of a hypothesis/theory, with no way to EXPERIMENT/MEASURE, what you're sure must be there, in some detectable way, or another.

Enjoy your snake oil. Anyone who says high priced power cords or speaker wire changes the sound is lying, ignorant,or a victim of confirmation bias.

@rodman99999 My ed is in applied math, signal processing and hobby is DYI audio. I don't specialize in avionics, it is just I tend to look up what is used in real advanced cases. Just to be sure there is no Barnum... I've seen "big box" fancy looking gear, but when opened it was basically empty inside with 3"x3" poorly soldered board and unshielded power supply. But it costed $$$. So I always check the engineering side.

There is a list of MILSPEC cables that list material, shielding, etc. So it is handy to check if that exotic metals cable wrapped in Japanese silk is truly necessary :-)

Well then Pass is a well known and admired popular brand in the audiophile world. I would like to know if others have used up market cords with Pass and found they did improve the sound.
 

I have owned the following Pass amps: X250.5, XA30.8, X260.8 mono blocks (my current amps). I’ve also experimented with several power cables. I heard the difference every time. The change isn’t always positive. But it’s there and is audible. 
I had Pass XP-12 preamp and now running XP-22. Power cords make a difference on these preamps as well. 
 

As a matter of fact, I’ve not yet owned a component that didn’t react to power cord changes. 

@mikhailark -

...selected to deliver power in environment full of RF interference and when performance may literally mean life or death. They would perform well in a less hostile conditions :-)

     No doubt: they're selected to dependably deliver DC voltages, under those conditions.

     Personally: power cables designed to conduct (perhaps: purify) AC voltages, or: ICs designed for the highly complex musical signals I enjoy, are my preference.

      When it comes to performance, in life and death situations; it's been my experience: firearms are much more dependable.       

      Out of curiosity: what brand of fighter jet cabling have you found to use in your system?

       How did you do your research, or: have you schooling in Avionics?
