Ideal power cord lengths?


A quick Google search suggests there is consensus that the ideal power cord length is 2m.  1m cords sound “harsher” and 3m cords sound “smoother”, with 2m being the sweet spot.  The PS Audio dude suggests that the reason is that the reason is that all cords have an impact on the power, and the greater the length, the greater the impact, good or bad.

I know many will say there is no difference between a 1m cord and a 3m cord.  But my question is, who here has tried like model power cords of different lengths, and what were the differences?  
 

Second question:  How does length factor into the equation when you have a cord feeding a conditioner, then other cords feeding components?  If 2m cords are in fact the ideal, would 1m cords be ideal when using conditioners?

I tend to believe those that say that power cord lengths matter.  While I’ve not been able to do this test myself, I’ve had these two experiences:

  • Testing Audioquest Diamond and Nordost Valhalla 2 USB cables, the cables shorter than 1.5m sounded TERRIBLE by comparison.  Especially the .75m Audioquest Diamond vs the 1.5m version.  But the 1m Valhalla 2 also sounded awful in comparison to the 2m version.  In general this opened my eyes to how much cable length matters, and counterintuitively in the case of digital cables. 
  • I have a 2019 2m AudioQuest Hurricane Source cable from back when AQ braided their cables, and I also have the newer non-braided Hurricane Source, but 3m in length.  The new Hurricane sounds vastly superior to my old 2m Hurricane.  In comparison the older cord compresses the soundstage depth.  I don’t know if the differences are due to the differences in length, or if it’s due to a design change by Audioquest.

Very interested in learning of others experiences with power cord lengths.

I have  a transformer right outside my window and dedicated circuits to my music room. Mono amps share one furutech outlet and the other gear is on a Furman it ref 20 I,  it's plugged into a wattgate 381 AU evo clear outlet.  This outlet shares the lights and two other outlets but I keep the light out and nothing else on those other outlets.
All  12 awg I installed myself through the whole house when I built it.

I made the mistake of building some one meter pc's and there two short for right now so I have two meter analysis plus ovals, I don't know why someone would pay 2600 for them, I damn sure didn't, I bought them used and put some furutech ends on one of them.
I have some pretty clean power but will do better one day. If you plan on using furutech dps 4.1 better make them 1.5 meter. 

@bikeboy52 

Will be posting pictures shortly, we’re down to minor drywall and paint. As usual will do it in a month turned into six…lol. Overall I’m happy with what’s been done. PM me if you want a little info 

Cheers

@1971gto455ho Could you post some pictures of your system? Im thinking about making some changes to my mine and am curious about all that you’ve got going on there, thanks in advance. “Pony” panel especially,Ive never even heard of that before.

I find the two meter sounds better than one (or shorter). This makes me think of the length of wire from breaker box to room receptacles. And of course the type of wire.

I believe we are limited by practicality. 

The late Bob Crump determined in his extensive tests, that 7.5 feet was optimum and any lengths longer would not give any more sound signature of the given cable. Of course he did not test 100 cable brands, nor has anyone else. It would take too long and cost too much.

I have found with shorter than 1 meter cords, the Belden 12 AWG ( or generic similar) with a better IEC connector, sounds very good, and better than some custom cords. For longer than one meter, choose an Audiophile power cord. 

 

Power cables need capacitance…Long ones have more.

you can even measure that!

shunyata ideal length is 1.75M.

voodoo 2meters

wireworld 3 M

you see they all vary

 

3m is too long. In my book, the sweet spot is between 1.5m to 2.0m which is about 5 to 6 ft. Both Wireworld PCs which I own are 1.5m in length.

I always take info from vendors with a grain of salt. I had thought Nordost recommends 2m power cords but I could be mistaken. I once found a link on these boards to a Nordost Q&A that lists recommended lengths for all types of cables. The PS Audio guy also recommends 2m as “the sweet spot” and said he has a number of theories as to why, inferring that longer than this can be worse.

Regarding pricing, yeah, all HiFi vendors are seemingly making ridiculous margins. I just bought some Herbie’s Cone/Spike Decoupling gliders for my speaker spikes to sit on. They are considered the “budget” option for these types of products (but people report positive results). But for the life of me I can’t see how these would cost a manufacturer any more than a few dollars more than a standard set of furniture sliders from Home Depot. Cable companies get picked on but it’s all types of HiFi vendors really. On the flip side the HiFi market is minuscule. For anyone to be in such a low volume market, it would only make sense if the margins were exorbitant with the small number of people in the market willing to pay.

Of note, yes, the Herbie’s gliders do seem to make an easily noticeable difference. I tried putting them on one speaker and not the other.  That made the differences really obvious.  But I don’t have experience with similar products and I’m guessing others are effective as well.

PS: Even Audioquest does not ship their Niagara Power Conditioners with a power cord (nor Denafrips).

From their website:

Niagara Noise-Dissipation Systems do not ship with an AC cable. Why?

The cable that feeds any power product is the most important AC cable in the audio/video system. For any power product to maximize its ability to dissipate noise, the attached AC cables must be Direction-Controlled to drain induced radio-frequency noise. AudioQuest AC cables include ZERO-Tech for uncompressed current transfer and optimal Noise-Dissipation. Further, our patented GND-Tech (Ground-Noise Dissipation) pulls RF noise out of any product it’s attached to.

When partnered with a Niagara power product, our Direction-Controlled AC cables create a complete Noise-Dissipation System, ensuring the most effective and efficient dissipation of RF noise.

We allow our customers to select the appropriate length of cable for their systems and to decide how completely they’d like to optimize their Niagaras.

 

Great thread and info! Since I DIY my PC's, just ordered new bulk. I will use existing Wattgate connectors to test before converting each cable to a new length. It's as good a time as any to order a couple different brands of bulk to try.

Checked and NO Shunyata nor Nordost bulk LOL!

Of course Nordost recommends 4 meter LOL!

Audioquest is a unique cable mfg/distributor. Yes, big $$$$ in R&D but in advertising and "shelving" as well! As one poster mentioned, gauge is smaller, forget molded connectors vs. good quality connectors cost wise. $2 vs $100 mfg COST! At AQ's massive mark up those two connectors would cost you $1000.

It only takes a stripper and screwdriver to DIY them.

OP

+1

I have always actively not wanted to hear a difference in accessories. I did not want to add more layers of difficulty to the pursuit. But virtually anything I have done… wires and others including springs and other vibration control stuff has demonstrated it matters. 

@mirolab , as I noted I’ve not conducted a test of different lengths of identical model power cords so I cannot speak to any differences. I was simply asking if anyone had actually done this test. Quite by accident, I did find that longer USB cords are obviously superior than 1m or shorter ones. I verified this through blind tests after, which was quite unnecessary as the differences were so obvious in my system. Tested two Audioquest Diamonds of different lengths and Nordost Valhalla 2’s of different lengths. I simply asked if anyone had done this test with power cords as I’ve read from a few sources that it matters.

@ghdprentice was the only person who actually did the test as a result of this thread, and found that longer cords improve the soundstage, which is consistent with what I’ve read elsewhere.

As for power cords in general, as vastly entertaining as it is to endlessly discuss whether they make a difference (for decades!) there is a very simple alternative to answer this burning existential question for all members of humanity who are privileged enough to be able to get sample cords from a dealer. Go try a test, yourself, in a system that is configured to be moderately revealing. I don’t have stats but I know only a few who have done this test who can’t hear a difference. And you don’t need to be an audiophile to hear the difference.

That said, the discussion is still fun, albeit utterly non-productive. The only way to resolve this is to see if you can hear a difference. When I think back to when I was a bit younger, I too didn’t want to think about the differences a power cord could make, even if I actually knew they played a pretty significant role in the performance of a system (from a test I did when I was young). But I didn’t WANT to think about it because my entire focus was on being able to afford amps and speakers. So even though I knew there was a difference I lived with stock cords for many years. I have premium power cords now, and while a wouldn’t say I consider them to have the effect of a major component upgrade, the improvement they make in my system is not small.

Many audiophiles refuse to engage on this topic as the discussion is futile if people aren’t willing to try a test for themselves.  But I get a kick out of the discussion….

@soix 

I've had a home studio for 25 years, and been in several studios, looked behind the racks of multi-thousand dollar processors, all plugged with generic black IEC power cables.  So YES i know the difference between those cords, and the ones used on the monitoring system.... BUT there is so much more going on with the power than worrying about the LENGTH of each power cable, as the OP is inquiring about.  

Is the OP really hearing a difference with different lengths of power cords?? I don't know.  But if he is, his solution is going to be unique to his particular setup.  I can guarantee that someone else, in a different location, is going to get different results.  

Just like with audio recording & mixing... I can use the same exact guitar/amp/mic/preamp recording chain as "XX" famous guitarist, but try as I might, I could never get the same sound he's getting.  Every situation is different.     

Electrical insulators (like from power poles) are available on eBay from $15 to $35. I think they look great… and I have had mine for 30 years. 

Post removed 

Don't be so dismissive!  Recording studio can learn from audiophiles and vice versa.

There isn’t a studio in the world making records today that is worrying about the power cables feeding the racks of processors used to make a record.

@mirolab Can you share the recording studios you’ve had this conversation with?  Not that it matters because we’re not talking about PCs in the recording studio here but rather the PCs feeding home audio systems.  If you don’t realize the difference, please just go away.  Thanks. 

I was reading in a pro-audio mag, the writer’s experience attending AXPONA for the first time, and his head nearly exploding at the ridiculousness of power cables. This is really why people hate the word "audiophile".... because of this silliness. There isn’t a studio in the world making records today that is worrying about the power cables feeding the racks of processors used to make a record.

... just sayin......

Anyone wanting to try the cable lifter idea on the cheap (I have yet to install them), I have read that lots of people started out with Tinker Toys.....I believe Danny Ritchie at GR-Research recommends them to start out (believe he may still use them?)  Heck I bought two starter sets for $28 that will be enough for my whole system

 

OP,

 

I am happy to hear you want to hear the difference yourself with cable lifters. Tell us what your impressions are. When I was younger, I can’t tell you how much testing I did with interconnects and power cords… many, many hundreds of hours). It was time consuming but incredibly eye opening.

Vibration control. I have quite a bit of experience there as well. I have not had vibration control effect the tonal balance. Not from the old pneumatic (inner tube in a box), heavy composite platforms, springs, or high end platforms like the Silent Running Audio Ohio Class +++ made specifically for my turntable. They reduce the sound floor and focus images and sound… not change the tonal balance.

Cable lifters and vibration isolation are two areas I’m also gonna attack soon too, so I’m in the same boat.  For cable lifters, before buying something I might just cut out some rectangular pieces if cardboard, fold them in half and cut a notch in the top for the cable and see what I hear.  For vibration control I’m pretty much sold on Townshend Seismic spring-loaded isolation products as I’ve never read more consistent and overwhelmingly positive reviews of any other isolation devices.  A little pricey, but they sure seem worth it for the significant level sonic benefits they seem to provide.  Just a couple thoughts FWIW. 

@ghdprentice

👍

Often the best solutions are guided by pragmatism and common sense. Nothing beats actual hands on experience/engagement and simply listening. It seems some rely too heavily on preconceived beliefs and specs/numbers on paper. This is woefully inadequate. As you have learned, trying products and ideas in your own audio system is the definitive approach.

Charles

@nyev I have moved several times since the pandemic and so have had multiple times to hear the difference between before installing the cable lifters, and after. I use a variety of them with different heights to create a power cable height and a signal cable height. Every time, I procrastinate a little, thinking it will not make a difference, and every time I am shocked that it does. It’s as if the whole system was picked up and transported to the recording venue. It is like the system is not in my room anymore, but where the recording was made (not wholly, as my system is not perfect, but it moves in that direction). And there is just a sense of magic and wow that comes with raising the cables that I can’t put better words to. I use a a mixture of various Shunyata lifters and Audioquest Fog Lifters (good value, but I have not figured out how to get them apart for re-transport). All power and signal cable are up. Network cables are still on the floor and thinking about get more lifters to get them up. Makes a difference on both carpet and wood flooring. Enjoy!!

@ghdprentice , good point, and I agree, everything is additive. Might be worth just installing the cable lifters. That said, I’m still curious as to whether or not they might help.  I know there is consensus (of those who have actually done the comparisons) that cable lifters work, but I’m curious to hear the differences myself.

I’ve also read that vibration control for components do change things, but can impact tonal balance, and not always in a good way. There are so many anti-vibration products and different schools of thought. I do know enough to be aware that the mass of the component does factor into the equation, with ideal vibration being a function of mass, stiffness, and dampening.

OP,

 

Good idea. When I was new to high end audio I quickly heard important differences in speaker cables, interconnects and realized that this little stuff really makes a difference. Then I read an article in The Absolute Sound, in the 80’s… that one of the important writers had heard many good systems… but that every great system he had ever heard had all the details perfect… cable lifters, cables crossed at 90 degrees… etc. the point was… the little stuff is additive and matters.

 

So I bought vibration reduction platforms… and heard the difference. The power conditioners, and heard the difference. But when it came down to cable lifters… they are so cheap… I just bought them (ceramic electrical isolation devices) and put them under my cables. My time is not worth doing the comparison. They are universally known to improve sound… they cost almost nothing. After, the last 12 things I was told make a difference, and did… direct lines… power cords. I am happy to spend $100 on my $50K system on faith. Only my system is now worth $150K and those $100 of electrical insulators are there, and I feel confident they are doing something… and if not, I don’t care… my system sound great.

I just read the other thread on the merits of lifting cables off the floor with purchased or DIY cable risers - it’s even more contentious than this thread!

I plan to TRY using risers at some point, will attempt to do a blind test somehow, and then decide whether I believe it makes a difference or not in my system.

I will not blindly assume it’s silly, even if the concept is totally loony. Ears are the best judge, but part of the hobby is to work through any possible bias that might influence what we think we are hearing or not hearing. Bias is definitely a factor to contend with; I’ve encountered it myself and subsequently had to alter my assessments. Usually this only lasts for a few days when it happens though.

 

 

Takeaway from this contentious thread subject-NOTHING

If one thinks aftermarket power cables make for a "better" setup, then it does.

If someone is in the other camp-you're right, too.

I have overpriced fancy cables only because of smokin' deals.

One certainty-the supplied $1.00 rubber PC will make your component work.

@lalitk , I know it will make a huge difference, but thank you anyways! I am also considering what I can put in front of my TV while listening to music..

“TBH I’m not noticing any issues with my room, but I know it can be improved.” 

@nyev 

Honestly, you would not know how vastly your system sound improves until you start to treat your room. No matter how complicated your room is, GIK Acoustics can help you tame the room with a modest investment. You can thank me later :-)

Number one problem if you have a decent level of components is your source file. I spend time making mine right or deleting them if not fixable. At times the files need nothing which is good but even with the touted hi res music not a given. I fix up and sell used Klipsch gear and I used to get complaints that it does not sound as good as when I heard them at your place. I learned that I also had to tell my customers if you want the music to sound as good as what you hear at my place you have to do the same things.  Bad source files was the single biggest problem and the cheapest one to fix. Audacity is free and then your time to learn to treat files so you like them. I am a minimalist and I use the fewest number of items I can to get good sound as I figure them more I throw in the mix the more I have to try and make right as a cohesive system. So I have a PC that has the high definition driver for the sound card installed and used, feeds to my Crown amps then to my system for my smaller built two way. On my larger system mentioned in my profile I added a Xilica DSP since the horn throat is 108" and it need time aligned plus the K-402 horn works the best with DSP. I have people over on a pretty regular basis and it is funny to see some of them sneak a peak at the back side of my rack to see what the "hidden gear" is that makes things sound so good.

  What I have found is the minimum amount of gear sounds just as good and most of the times better then complicated expensive high end setups if it is done right and you have really good speakers + sound files. 

 

  I am no longer looking to improve my daily listener because it satisfies my desire for good sound. I watch the guys with lots of gear and see that most are never quite happy and change things pretty often. I think they have over complicated things beyond the chance of top level integration, if that is even possible with so many devices at play, and of course never look at music files. Speaking of which I never stream. I download and put them on a hard drive where I can edit the files if need be. I have heard to many setups with much gear and streaming I did not care for. I was not going to ask to slog through someones pride and joy to try and figure out what was wrong though so I can only reflect on observations.

I love how this cable (and in particular power cord) debate has raged on for decades….  It seems that both sides always end up talking down to the opposing side.  All over whether or not you believe a power cord makes a difference in your HiFi system, lol…. Oh well, human nature.  No wonder humans have fought wars for thousands of years. @mahlman , I think you are on the right track.  There is a perception of elitism that people probably find distasteful, causing the drive to be condescending and judgemental.

You are also correct that I am compensating for poor source files.  Lucky guess!  But I would present an alternate way of looking at this.  I want the convenience of streaming via Tidal HiFi and Roon, but I also want quality.  As such you are right, I’ve purchased two items to equalize my streaming performance to that of local high-res files.  The two components are the Innuos PhoenixUSB Reclocker and the Innuos PhoenixNet Ethernet isolation switch.  These devices (not cables) offer me the convenience of streaming combined with the quality of local high-res files.

 

 

If you have high powered class A amps. And live in a tract home neighborhood,

make them long enough to reach your neighbors side yard duplex. 😳

@audioman58 Wrote:

what truly counts are the end connection points , here purity copper with gold,silver or rhodium over the copper , with ,not brass which is bright and no where good of a conductor. 

I agree. One of the reasons I eliminated the power cords from my two monoblock amps was to eliminate two connection points, the wall plug and power cord male plug. Also, another reason is to negate the question to me about what power cord sounds best. Running my amps directly to the dedicated circuit sounds better, in my opinion, then running them with a power cord.  😎

@lalitk , I agree, I am going to tackle room treatment next, before dealing with vibration/coupling.  But I might start considering vibration control and learning more about soon as I simply plan to engage a qualified expert to specify how to treat my room.  I think my room is more complicated than most as there are angles, open walls, high ceilings, and it’s not simply a rectangle like most rooms.  TBH I’m not noticing any issues with my room, but I know it can be improved.  I’ve had terrible rooms before for my system but not this time.

Nyev, Soix, CurtDR, and all of you are correct. Of course there are ALWAYS differing opinions when discussing power cords, or interconnects, or HDMI/Ethernet/USB/I2S cables, or balanced vs unbalanced, or clean power, or separates vs integrated, or room treatment, or price of a system, or whatever it is that gets us going.

I am on a different journey from most of you, I have a budget that I am comfortable with, I prefer a different "sound"  from my system, I listen to different music, and maybe even different volume levels, and there are things about this hobby that bring me pleasure.....like tube rolling in my VTA ST-120 amp, or cable rolling, or trying to extract just that little bit more quality from the system that I can afford.

Truth be told I am jealous of those of you who can afford $15,000 speakers/amps/pre-amps/DACs and wildly expensive cables.....I am positve that you can extract better sound than I can out of my $15,000 total cost system. But that is a cap based on my particular financial reality.....and my  wife's patience. And frankly, it has taken a ton of time and research (many suggestions gathered here) to find reasonably affordable products to give me the best sound (for my ears)

Yes of course I know that a better pair of speakers will have a greater sonic improvement than a Audioquest Vodka HDMI I2S cable, and KrellAudio Research/Wilson products will outperform my Denafrips stack and Buchardt S400 MkII speakers. But I have a damn fine system for my needs and sounds amazing at low, mid, and loud listening levels, and I'll continue to find each little tweak I can afford to improve it.....and I will be getting some GIK products for room treatment, so that's another rabbit hole

There is a principle involved here. Only if you spend lots of money improving something of extreme minuscule benefit that only a meter could possibly measure can you be judged worthy to have an informed opinion.

 Right there at the top of the list from Audiogons weekly update was this jewel. Only on Audiogon do you get such priceless topics and pithy answers. The surreal ones from believers and the amusing from those of us who know better. In the mean time I bet the OP has bad music files and trying to fix them with stuff and not Audacity, Thanks for the chuckle of the day though.

“Next up for another highly controversial subject: isolation and/or vibration control!”

@nyev

I just looked at your system pics and don’t see any room treatments. If you haven’t already, I would focus on room acoustics before you spend a dime on isolation/vibration control devices. Room acoustic treatments should be the first and foremost part of any serious listening space and fundamental to getting the most out of your audio system. I recommend consulting with GIK Acoustics, they were very helpful when I treated my room few years back. 

I am assuming you will be starting new threads on room acoustics and vibration control :-)

@curtdr Im in finance, and a lot of my clients were very happy to be partly in managed futures (it’s called diversification) while the market was collapsing in 2008 and those funds were making money hand over fist. Sure they may underperform the market from time to time — every asset class does dude — welcome to investing. But what they saved my clients from the crash more than made up for any net-of-fees underperformance going forward. But again, keep that head in the sand and you’ll know no different nor learn anything. Like I said, it’s certainly easier that way.


my hope for you, in all sincerity, is that you someday find your own comfy satisfactory hole, or if you do not, then you will be comfortable with eternal wandering. It’s all good, whatever path you choose.

I’m very satisfied in my hole because I made the effort to be open minded, continue to learn, and explore what else is out there. To me, that’s part of the fun and great reward of being an audiophile. If the head in the sand method works for you, great. It’s a much easier life but also much less rewarding because you learn nothing further. How fun and enriching that must be. Ignorance is bliss is your friend along with plastic, generic power cords. Enjoy that exciting world of yours. I gladly choose and embrace the other.

 

I mentioned already but for me the stress of figuring out how to solve my system issues related to some sonic aspect that troubles me is FINALLY over. I find now it is more relaxing, and in fact highly enjoyable, to consider how I might improve my system. But the beauty of where I am now is that I’m in no hurry to do anything, because I think my system sounds fantastic. In fact, I already have a mix of 2m and 3m cords already! So no rabbit holes necessary.

I asked this question purely out of genuine curiosity to see if anyone had experienced comparing like power cords of varied lengths, and what effects there might be…. @ghdprentice did the comparison and he found he preferred the longer cord, while also confirming what others have said about the sonic differences that power cord lengths make, when used in highly resolving systems like @ghdprentice has (beautiful system btw….).

I suppose I didn’t start the thread for advice on my system, but rather simply to share experiences and maybe learn something about our hobby from other.

Next up for another highly controversial subject:  isolation and/or vibration control!

@soix

Ad hominem much?

By your stridency, I do believe I’ve struck a cord... er, chord. 😉

Yes, fine, you and some others have experienced "significant improvements" in the sound of your system by buying expensive cords... great. Enjoy.

Experience = subjective, by definition

Significant = subjective, usually, unless tightly defined

even Improvements = subjective

if we do adhere to the concept of let your ears decide...

... and if the OP wants to follow you into that replacement cord tangle, that’s fine w me... we all have our hobby or hobbies, right?

This subject reminds me of finances, in more than one regard. Esoteric financial products are not superior to intelligently implemented simple products. Many people buy way more insurance than they need... including "whole life" products... because they either don’t know the research or just because it makes them feel better. High priced hedge fund or other active professional managers, or amateur active traders, do not beat the indexed market in the long run, especially once the premium fees are extracted. Any that do, do it by statistical luck, not skill. But, people who buy into all that esoterica in the face of overwhelming long-term academic research to the contrary often feel better anyway and frequently think themselves smarter than us "uneducated" schlubs with our heads in the sand of our low-fee index funds... And that’s fine too.

It’s good to have a hobby, and I’m glad you found one that gets your juices going... more power to you and your system... my hope for you, in all sincerity, is that you someday find your own comfy satisfactory hole, or if you do not, then you will be comfortable with eternal wandering. It’s all good, whatever path you choose.

Few people follow the rabbit holes I follow through Kant and Wittgenstein, so hey... and I don’t blame ’em at all.

And it’s up to the OP or any other audience member to weigh it all out, consider his own priorities, and choose his or her own path, as well.

So, yes, follow your bliss, and if that means pouring money into... cords... well, so be it. Myself, I’m not following into that questionable hole

@curtdr Yeah, you’re obviously right and the rest of us who’ve found PCs to make meaningful improvements are just kidding ourselves along with the manufacturers of equipment who never, ever use stock PCs either. You keep rocking those black plastic throwaway cords and reinsert head back into that much more comfy hole in the sand rather than daring to explore ours. It really is so much easier for you that way — I’ll give you that. Enjoy.

@ghdprentice 

I agree with soix, very well stated and reasoned reply. I've reached a point where I don't bother with those who are skeptical of what others report with regard to hands on experience in High End audio. That's their choice and issue. Listening is the best method for deciding what does and does not produce meaningful results. This approach has served me well.

Charles 

@ghdprentice

@soix

etc.

Thanks for the welcome, but it’s misplaced.  It's far from early in my journey... But thank you anyway.

Yes, indeed, ears as arbiter I understand very well.

I also understand confirmation bias.

But if spending even more money on a 20k product for a power cord is necessary for you to hear "large improvements"... well, er, then I’d call out the manufacturer on that one because the amp must have some design flaw, because with a good enough amp there’s no such thing as "large improvements" except for system synergy with speakers, maybe dac, maybe... subtle, perhaps audible or perhaps psychological, improvements perhaps... One hopes to hear "large improvements" when one drops $500 or $1000 or more on a power cord or an interconnect, and hope leads to belief leads to thoughts of even greater nirvana if only, if only...

And I also understand priorities, to each his own there, financially and otherwise.

But as an educator, and as an educated long-time audiophile on the side, I do not agree that ignorance is bliss... and I’m also aware of endless, self-imposed rabbit holes that intertwist and eventually lead to more rabbit holes and never a home. So, if that’s where people want to lead the OP down, and if the OP chooses to follow, well then that’s your priorities and the OP’s priorities.

In my considered and experienced opinion, if you’re not satisfied with the sound of your system, and if you have a well-designed modern amp, you’re better off trying different speakers that are more to your taste than dumping money into cords and interconnects.

So, yes, follow your bliss, and if that means pouring money into... cords... well, so be it. Myself, I’m not following into that questionable hole, however, and the OP will just have to weigh everything out and decide for him or her self.

Early in your journey, when you are stretching just to get into what may be barely considered “HiFi”, speaking from my own experience at least, your mindset is just on obtaining the gear you can barely afford. The last thing you want to hear is that you should allocate a portion of your budget for cabling, including power cords..  It’s far more convenient to believe it’s ridiculous that power cords have an effect, and it IS a ridiculous concept.

I believe this is partly what has driven people to be so passionate about this debate for so many years, using the same common-sense based arguments that don’t apply, and passionately doubling down while refusing to find out for themselves by doing a simple blind test in their local HiFi shop. It’s far more convenient, budget wise, to believe that aftermarket cords make no difference. Very few people won’t hear an improvement with premium cords in a blind test when they actually get to doing it, and you absolutely don’t need to be an audiophile to hear the difference (my wife and daughter hear obvious differences but couldn’t care less).

@ghdprentice Well said.  You’re a good example of someone benefitting from keeping an open mind and letting your ears being the final arbiter versus just sticking head in sand and calling it a day.  Ignorance is bliss, to each his/her own, etc.
