Obviously a noivice hear - Dynaudio Audience with Marantz AV Receiver for HT use only.

The last time i upgraded my speaker wire was 10 years ago - bought an "upgraded" caliber speaker wire that was about twice the guage on the recommnedation of the salesman at the time. Who knows if it was worth it.

Has anything come out that warrants ditching the old speaker wires that worth investing more money than i already have?

Stick with your speaker wire if its in good shape. If not consider some wire from Blue Jeans Cable -- Quality Cables at Reasonable Prices (http://www.bluejeancables.com) Their 10-14g speaker wire is a great buy if you buy it unterminated and apply the spades or Banana plugs yourself.

To my ears solid core cables are superior to stranded cables. Check out AntiCables and Audioquest since they both offer affordable cables using solid core wires. Solid Core cables are more focused and do not have the fuzzy strand interaction that bothers me with stranded cables.

You can spend a lot of money on wires and interconnects. All for dubious improvements at best. Loudspeakers provide so much variation that any possible changes wrought by switching wires and interconnects is lost. Unless, of course, your original wires and interconnects were simply inadequate or too long.

I have always suggested that wirephiles connect their new dream wires only on one channel with their old and unloved wires on the other channel and then pan back & forth to listen for any differences. As far as I know, none have ever done this. By the time you finish changing out ALL of your wires your memory of what you had will be lost so you will hear whatever improvements you wish to hear.

I have never purchased expensive cables. I would like to try some top level cables to hear if there are any benefits. The most I have spent on speaker or interconnect cables have been $250 a pair. I do not consider those as expensive.

Today my thoughts on cables are solid core with minimal dielectric and minimal jacketing. The more I listen to the AntiCable speaker cables and the DNM Reson IC's are the way to go. I hate to speak of other companies but Audioquest are good cables but I can understand why they had to develop the DBS system to counter the effects of the insulation.

Geortz Alpha core is another solid core brand using minimal dielectrics. I like their Micropurl IC's but their entry level speaker cables roll off the high end.

I have just one comment about the AntiCable speaker cables. I bought two pair to bi-wire and hooked them up without twisting the 4 wires per side. Later I twisted them and the longer I listened I thought where was that magic I first heard. Instrumental texture were missing and a prevailing glassy sound to the music was added. I removed them and put another solid core cable but then a banana plug came lose. Something made me think to untwist the cables and when they were hooked up the magic was back. The cables are only $10 a foot/pair.

Progress in cable design involves quality of conductors with less impurities and crystal structures. Less dielectric is a good thing and Tara Labs uses solid core in a vacuum at a very high price. Geometry is also important. DSM speaker cables and IC's are kept a consistent space between each other and is not and cannot be twisted. Other cable makers twist their conductors.

Conductors, insulations and geometry is where most of the improvements have occurred and that is what makes up a cable.

The reason for using braided audio wire is that such wire is very flexible and therefore not at all prone to work hardening from being repositioned to curve around obstacles. House wiring can be solid because it is seldom repositioned, but audio wires may be repositioned many times. The latter is the reason that oxygen-free copper is often specified for solid wires: oxygen-free Cu is resistant to work hardening. That is, using solid wire creates the need to use oxygen-free Cu.

I have the big 4 wire Audioquest only because it was given to me by my son-in-law who's in the business. At the moment it's in the garage as it sounds no better than the Walmart Woods Patio Power Cord and I don't care for it's weight and stiffness.

40 ft of the Woods Cord sells for around $10 plus you can use the male and female ends for other projects.

I just like to know what we are comparing. By Semi-Solid does that mean it is a mixture of solid core and stranded cables? I have a pair of AQ cables that are stranded and they are not in the same class as their solid core cables. The better AQ cables are all solid core.

I'll say it again for anyone thinking of spending large sums of money on speaker wires and expecting return on their investment.

If your speaker wires don't degrade the sound, then those wires are the best you can buy. Speaker wire degradation like pregnancy is not measured in degrees. It does or it doesn't or it is or it isn't.

There are so many worthwhile upgrades to one's system such as better tubes, capacitors, resistors, phase plugs, dampening, room mods, cone treatments etc. that it's shameful to delude newcomers into thinking high priced wires can make a difference vs non-degrading cheap wires.

JohnMichael
06-07-2012, 08:37 AM
Point-Counterpoint. Cables have their own electrical characteristics and those characteristics can work well with the components they are linking together or degrade the sound because of mismatched characteristics. Cables at the midrange price range can be a cost effective way to achieve synergy in your system.

Cables are a component in your system that are probably the most trouble free. They have nothing to break down or wear out. I did recently pull a banana plug from a speaker wire and you really do want to pull on the plug and not the wire.

Talk to your local dealer and ask if he has any wires for an at home trial. Until you try different style of cables it is hard to tell if they are a positive or negative.

Like many things in life some are more able to hear differences in cables. Differences in cables may be more noticeable in two channel systems than multiple speaker processed systems. When I add a new component I change cables to hear which sounds best.

My system is not finished until the cables have been selected.

Give it up, Pg. You are arguing a religeous question. People will hear what they want to hear.

I have read so much nonsense about wires I am forced to wonder how people can have so much free time and money for this.

Sell the flakey wire and use the money for your other projects.

My favorite (beyond the exotic geometries jazz) is the use of OFC which MIGHT be beneficial in heavy solid conductors to prevent cracking. Oxygen-free copper was developed to allow generator armature windings and stator windings to be formed (bent) into their required shapes without cracking from work-hardening. There are no electrical differences between oxygen-free copper and standard copper. This is from the company that developed OFC. But many here are "sure" that they can hear the difference provided by using OFC in lieu of regular Cu.

People are so hungry to improve their systems yet lack the courage to try a real upgrade. It's sad that boutique wires end up being the best they can do.

JohnMichael
06-08-2012, 12:45 PM
One of the things I have found in my sampling of cables is that a single solid core cable sounds best to my ears. The timing of all the notes traveling that single wire in time creates a better soundstage. Even a cable that uses individually insulated solid core conductors of different guages can interfere with the timing. All my IC's and the AntiCables are single conductor for each polarity.

The next cable I am thinking about is the DNM Bi-wire speaker cable. The four solid core conductors are molded to keep an even distance between conductors. The two wires for the negative and two wires for the positive are set to reduce electrical interference and eddy currents.

I do not need cables but I like to try cables much the same way someone might upgrade an amps capacitors or try a new set of tubes. The only part of my stereo needing upgrading was my turntable. I have replaced the motor and added the power supply upgrade so I am happy with the perfformance of all my components.

Since the money I spend on cables or tweaks is rarely more than a nice evening out with a show. The cables and tweaks I will have for a longtime, long after the dinner has passes and I sober.

Mash

Now I understand.... Those of us who cannot hear differences amoung cables are defective. I guess we should junk our soundsystems....

Let's see: New Magnepan MMGs can be bought for $600 delivered. How many nice cables can I get for $600?

Which will do more for most listeners?

BTW someone pointed out a dealer's negative (does-not-recommend) attitude toward the MMG ... well, guess what? Dealers do not sell the MMG. Magnepan sells the MMG directly to the buyer and within 6 months one can then trade their MMG in for a $600 credit at their favorite Magnepan dealer. Then what happens to those MMG?

I was once interested in trying Mapleshade speaker cables and they are solid core twisted cables. My experience twisting the AntiCables and using some Ultralink stranded cables that are twisted has left me with the impression that twisted cables will have some brightness in the upper midrange and highs.

My first solid core cables after my experimenting with Radio Shack solid core hook-up wires were Nordost Flatline Gold. My system has improved so much since then I may try some of their entry level cables again.

As I continue my experience with cables I will avoid both twisted and stranded cables.

There have been some speaker cables that were known to destroy amps. An early example was a cable from Polk Audio. Two of the larger AlphaCore cables needed resistive elements to mate with some amps. I do not know if any amps are at risk today.

This argument seems to crop up periodically, year after year. "Wire is wire," and "cables don't sound different" are statements made often, with which most of us at this site disagree, based on our own experiences.

I'm often shocked at the high prices (in the thousands of dollars!) some cables demand, and have no intention of every trying out any such cable. On a more "down-to earth" scale, I've had many success stories when it came to replacing speaker wire, interconnects and power cords.

The "bug" bit me in the late 80's when I replaced 14-guage zip cord with "Original" Monster Cable, and noticed a very significant improvment across the audio spectrum. Years later,I spent a small fortune (even at a substantial discount) for Audioquest "Crystal" solid core speaker wire: harsh, "in-your-face" and just plain awful, plus it was almost impossible to work with since it was so stiff. Monster Z-3 replaced that cable, and I've been delighted with it since, though I suspect there are still better cables out there, but at a price.

The largest single difference any cable made in terms of improvements was the AlphaCore TQ-2 solid silver interconncects I used from my SACD player to my preamp. I believe at the time they cost $275 for a 1-meter pair, but rarely was money better spent.

Audioquest has an arrangement with Audio Advisor for an interconnect called "Black Mamba II" which, for the price, is certainly worth trying. It sure improved the sound of my system by replacing Monster M-1000i, which sounded pretty good to begin with.

Then, there are the Pangea power cords, all of which cost a fraction of most "audiophile" power cords, and all of which made BIG differences in my system.

All that said, I'm sure several will still say I haven't a clue what I'm talking about. Be that as it may, others who,like me, have dabbled in this area, know what we hear. Would replacing my power amp and pre-amp with new units, costing about the same as my car make a difference? I'm sure they would, but expenditures of that nature are out of the question. If I can spend a few hundred dollars (or less) and hear an improvement, that, to me, is an "upgrade" well worth the effort, and deserves to be recommended to others.

I am glad you are a moderator here, FA. Nasty turns are in the eye of the beholder. I consider it nasty to suggest to someone that they are not entitled to their opinions.

So someone "hears a difference" with wires? We cannot demonstrate that. It simply takes TOO LONG to change out ALL of the wires. Acoustic memories of the unfamiliar are simply too short.

At best one can use one set of wires on one channel and a different set on the other channel. Then pan back and forth to compare. To my knowlege no one has ever performed this test and demonstrated it to others of both camps. And it is an easy test.

I have experience with things electrical, including generators when I made decisions that involved sums running to more than 7 figures. And no one was looking over my shoulder. The company had full faith and confidence in my judgement... and so do I.

My 2 cents worth is that expensive cables are not money well spend for people with mid-level systems -- these people, including me, are better off putting the money towards improving other components.

What's expensive? JohnMichael says $250 isn't expensive. "Expensive" is relative, but to me that's a lot money. A 3 foot pair of Blue Jeans Cable BJC LC-1 single-ended interconnects is $31.25; anything more is expensive to me.

I don't say all cables sound the same; I do say that the differences are typically extremely small relative to almost any other component you can buy, and that includes things like tubes or opamps.

Emaidel are your TQ2 silver? I have the copper TQ2 and I was using them between the Marantz SA8001 and Krell S-300i. They are a good match when I use the RS6 speakers with their peaky treble but they soften the sound too much when I am using the OML1's. I was thinking I might like the TQ2 silver since I am listening exclusively to the OML1's.

When I mention that $250 is not a lot for speaker cables I am taking into account how expensive some cables are. I would never pay more for cables than I would for a car. I have some cables that are many years old and still doing their job. I wonder what it costs to replace a set of tubes knowing they have a limited life.

I think we all need to spend our money in how we see fit in ways that bring us joy. I as an in home caregiver do not make much money. I do the work because I am good at it and I am rewarded in other ways. I certainly do not have the money to buy something that is not a benefit.

I replaced the power tubes in a Jolida.... 4 Russian tubes at $27 each.

I bought 16 power tubes for my Futterman amps for $250.

Other tubes cost other amounts.

How long a set of tubes lasts depends on the design of the amp or preamp. Or whether the amps owner believes (for some silly reason) that the amp should be left on all the time.

The power tubes in my Futterman monoblocks worked fine for 13 years of heavy use. The power tubes were replaced when bias auto-adjustment circuits were installed.... just because.

I can garantee one thing.

Futtermans driving Tympani will make an improvement over other amps that absolutely dwarfs any improvement that any wire could ever provide.

The conductors in wires should last forever unless they become damaged.

The insulation should last forever in a home enviroment. The voltages are too low to stress the insulation. Other enviroments may lead to damage from, for example, sun exposure or petrochemical attack.

Generators must periodically be rewound to replace the insulation, which is stressed and thereby worn out by the high voltages (i.e. 14,400V).

During the last three years of daily use I've had two tubes give up the ghost. One was a Western Electric 2C51 I bought used and the other a brand new JJ EL-84. Money wise that comes to less than $50.

For the price of entry level boutique cables I can buy a matched pair of Shuguang 2a3 Black Treasures plus a quad of NOS triple micas. With those tubes no imagination is required.

I am trying to remember a cable Michael Fremer reviewed for Stereophile. It was a fiber optic cable with a transmitter at one end and a receiver at the other end. The signal would be converted to pulses of light that travels down the fiber optic cable to the receiver where it becomes an audio signal again.

He reviewed it positively but he took a lot of heat. Many found it not up to high fidelity standards. In his system to his ears it sounded good. He did announce he would not use it to review equipment but only for his pleasure.

Other odd technologies were speaker cables with water jackets.

Complication is often best avoided.

Balanced XLR interconnects are probably best if your equipment supports them. These are what I use in the kitchen because I have a 50 ft run and use Mackies. XLR adaptors work but they add expense and bother.

I only have one SS amp I consider competitive with tubes but I still prefer tubie amps with planars.

Since this thread is "Speaker Wire Developments in last 10 years?" I am going to visit some cable sites to see if I have missed anything. I want to read why JPL uses aluminum for their conductors. Crystal Labs is another solid core cable that if memory serves they use gold to fill in any micropores in the silver. Van den Hul used carbon conductors in some of their cables. Many of the cables mentioned are way out of my budget.

Mash
06-09-2012, 04:18 PM
AL is subject to oxidation. Some houses burned because it was once fashionable to use AL wires in houses and then those wires oxidized leading to fires. Not good. Also AL is a fatigue-failure pig. Avoid it.

"...use gold to fill in any micropores in the silver" This is a scream.

The Boeing Company has derivatives for their aircraft design, and in order of importance, they are:

1. Purchase Price (Self-evident, I hope)
2. Fuel burn (determnined by the efficiency of the engines).

Then, much further down, and I mean MUCH further down, because these modern wings are so very efficient, is



3. Aircraft weight. This is WAY behind Numbers 1. and 2.


GpE is used because it is more reliable than is AL, not because it is lighter. Also GpE can be "tailored" while AL cannot. Yes, E-S, I know my way around GpE.

Well, as I recall, you were confused about aluminum being oxidized as opposed to rusted... so YOU brought airplnes into this. Now perhaps you are a little more grounded, as it were, about AL, GpE, and airplanes.

Audio cables? I thought I made that very clear. Al poses real issues when used for conducting electricity. Only Cu, Ag, and Gold can be "trusted" but Cu has proven adequate in all cases. Fu-Fu dust aside, OFC is used for generator armatures and stators with excellent results for very many years now, so why guild the lilly?

JPS Labs does not use AL as the conductor. It is simply one component of the multiple metal alloy. The resistance of the alloy is quite low - .016 ohms for the eight foot run of speaker cable I use.

Mixing metals is tricky business. With many unpleasant results that sometimes take time to rear their heads. Simple is better.

The issue with AL is not its resistance per se, but that its oxidants are poor conductors. Cu does not pose these problems. Ag's oxidants are excellent conductors. And gold simply sits there. Why mess with success?

Yes, they are. Years ago, I spent what seemed to be a small fortune on a pair of Kimber, solid silver, twisted interconnects that were used between my CD player and preamp. I ultimately found them excessively bright, harsh and with little bottom end. Perhaps the silver in the AlphaCore cable is somehow different, because it sure sounds a whole helluva lot better.

But then, cables don't make any difference anyway, as we've been told. When will we ever learn?

@ Mash and PG

Stating the other side of the story is fine. It should have simply been "in my experience with my equipment, I have not seen the benefits of cables vs tubes or other upgrade and tweaks."

You have also missed plenty of cable arguments at AK. I have been involved in some myself there as well as at AVS.

Lets be real honest here too. For the sake of the OP, the first and best upgrade for him would be a real amp to drive the Audience, not sure which he has. They are a tough line to drive no matter what model and most mass market HT receivers will NOT drive these speakers to their fullest potential.(again not sure of model) I have 3 of them myself so can speak from first hand experience.

He may be able to alter his sound by swapping out the ICs between source and receiver more so than with speaker wire.

Just because you don't/can't hear the same differences as others still does not mean it doesn't exist. It just does not exist for you in your experiences.

I don't see how I disparaged you. You jumped in the thread claiming that anyone who believes that cables can have an effect on the sound is an idiot, in so many words.

Most everyone else described their personal experiences with cables up to that point.

What do I do besides listening to wires, which there sure are lots of around here since I have 5 decent systems.

My wife and I volunteer at a local Senior Center even tho we cannot be members and are both only 50. I take care of my home and 1/2 acre, my mothers cabin in the poconos, and my mother in laws house in Jersey all while we take care of my father in law who suffers from dementia in a lousy nursing home.

So what are you looking for? A big AR pat on the back?

And what does any of that have to do with the fact that you cant, or don't hear any differences in any wires? And you are free to believe in that as long as you don't trash others who think differently. If you lived close enough, I could easily demonstrate it with ICs.

My wife and I are retired, and are both active in our church. I sing in the church Chancel Choir, and have even performed a couple of solos. The choir also performs whenever there's a funeral service, whether or not we knew the person who passed away.

I also sing in the Spartanburg Festival Chorus, which puts on a performance of at least one great work twice annually. Having been a member of the SFC allowed me the opportunity to travel to Prague last year, and sing (along with 263 others) in the Prague Choral Festival at Smetana Hall.

I also record books for an organization called, "Learning Ally." Its former name was "Recording for the Blind and Dyslexic," so that should give anyone a fairly good idea who uses the material we read. Thousands of students across the country have managed to achieve college degrees as a result of our efforts.

And then too, I purchase new cables and speaker wire, and listen to - and appreciate - the differences. So one can make a difference for others in this world, and still hear the difference between cables.

This is another problem with Nay Sayers. All they do is read and most of them never even try and experiment for themselves which makes them sheep in the religion of nay sayers.

I don't know what your reference system is but maybe it won't matter for you and that's great because nobody told you to go buy anything.

The last cable thread at AK that was closed was in the TOL forum and was about the fact that even when like minded people who choose on their own to experiment with and talk about real experiences, why do the nay sayers always feel that they have to chime in and save everyone from themselves.

That is what I see you doing here. The OP asked 2 things. If there were significant developments in the last 10 years, and if anyone thought he should upgrade his cables.

Again, if you had nothing in your own experiences to add or to say that you cannot hear any changes when you tried cable x or y, then really all you can add is that you Read something that someone else who didn't try anything wrote.

Also, some of us come by decent cables in odd ways. I got over $2K worth of Synergistic cables when I purchased a whole system for $300. The cables bested what I had so of course I use them.

Audio cables? I thought I made that very clear. Al poses real issues when used for conducting electricity. Only Cu, Ag, and Gold can be "trusted" but Cu has proven adequate in all cases.
Historically accurate for in the house use. The big problem was the combination of Al2O3 which is indeed non conductive, with connector hardware designed for use with copper wire. Aluminum has a TCE of 25.5 ppm/degree C, copper at 16.6 ppm/degree C.

However, pigtailing and the use of a flouride paste has solved those in the residential arena, the power company, as well as by those who use aluminum stabilized niobium titanium superconductors.


P.S. I love the trem "Audio Cable Design". This gives audio cables more gravitas than they deserve.

No. There are also people you classify as naysayers who attempt to understand why cables possibly could have an effect. Most of the explanations given just don't make the grade. The lack of a viable explanation certainly doesn't make it impossible, but most scientific types can't get past the fodder presented as science.

I approached some neural/hearing researchers about 10 years ago with a well constructed scientific explanation and test setup, they could not get past the foolish cable yaysayer/naysayer garbage.

I have no issues with nay sayers that have actually tried for themselves and just post that. My problem is when people who have never tried for themselves just start spouting off about what they have read and believe.

If a person who seriously believes that there are no differences in sound between ANY 2 cables jumps into a thread and claims that anyone who does think they hear a difference is an idiot, and they have never tried it themselves with a system transparent enough to display the differences, then I have a problem.

If the non believer chimes into a thread like this and says "from everything I have read, along with personal attempts with my own system, I cannot hear a difference and do not believe they exist" then that is an appropriate response, not that I am an idiot and have wasted all my money and so on.

Non belief is no less of a religion than those who do believe.

Again tho I will state that I have not played around with enough Speaker Cable to have a strong belief one way or the other but I do own ICs that alter the sound depending on the components connected to as well as where in the chain they reside.

You don't have to believe it, and maybe if I demonstrated it in my home you would not hear it. And that is fine too because at that point, you would have actually tried as opposed to just repeating whatever you have read and believed up to that point. Then you could post about your real world experience instead of quoting or paraphrasing what others have written, and a lot of times without actually trying it out first.

But the person buying the cable may not perceive the purchase as large sums of money. My AntiCables were $10 a foot pair. Or in my bi-wire case $20 a foot pair. My AntiCables cost $160 for the bi-wire cables. I also had the ability to return the cables if I was not happy. So my liking of the cables was not influenced by the purchase price. I have $2500 more reason to like my Krell S-300i. If I had a system worth $100,000 I might buy cables costing thousands of dollars.

Value is in the eye of the purchaser. Some friends do not understand my love of art and why I spend what I do but not Edvard Munch prices. Cars to me are A-B. I want basic transportation to take me from A to B. We all have to decide what is worth our money.

2 different discussions

1- do the laws of diminishing returns kick in with cables? I say yes

2- can differences be heard between some cables? I say yes


But, not all of us spend ridiculous amounts on cables. I have $60 ICs that sound different with given components. I also have $350 ICs which cost me nothing so I have not wasted any money and I can enjoy the fact that most of my cables were well manufactured and terminated properly with good materials. What is so wrong with that given that I don't care to be a DIYer?

Over at AudioAfficianados, they are discussing the benefits of a pair of $28k cables. Do I think that's over the top? Yes but the people discussing them and purchasing them are apparently millionaires who also don't give a hoot about DIY and don't seem to mind spending their money on expensive cables. But why not when the rest of their setup is already in the plus $250K range.

You claiming that anyone not running a flea watt SET amp with OB or single driver speakers is wasting thier money is no different than me claiming everyone who spends more than $25 on a watch is too. But it's about more than that isn't it? It's called Personal Preference which cannot be regulated.

From your responses, it does not imply you on one side of the fence or the other. In the off chance you were just doing what Smokey tried two weeks ago, I responded the way I did.

If you have tried rolling cables and never heard a difference, that qualifies you to say just that. And those that roll them and think they do hear differences, that qualifies them to say just that. But people who just read and repeat are not qualified to say anything but just that, that they have read somewhere bla bla bla and have never tried for themselves.

I understand the theories and the fact that cables not connected to anything measure a certain way. But I do not buy into those who say that there is no way any 2 cables can sound different when connected to different components.

I personally have just cured one of my systems of being bass-less and made the setup really enjoyable with the same single pair of ICs that made another system horrid and a 3rd setup lose what it had with better ICs.

Maybe I'm crazy but I'm the one who lives with and has to enjoy my systems. I would love to show/demonstrate to non believers (as opposed to naysayers) what I feel makes changes in my setup but have never had a taker to the offer and of course they are no even willing to try because it's not a scientifically based DBT. That tells me they are more afraid of what they might hear and cannot explain away with white papers than them not hearing anything different at all.

The pic didn't show up. It doesn't matter though.

For speaker wires, the only things that matter are distributed R, L, C, and length.

The effective dielectric constant, characteristic impedance, and propagation velocity can be derived from the first 4.

It is trivial to duplicate any cable out there using off the shelf materials. How it looks is of no concern. (well, let's neglect the eye candy thing).

And very few engineers out there can appreciate or understand what is actually happening when a cable is connecting a very low impedance amplifier to a variable impedance load using a wire of impedance significantly higher than the nominal of the speaker.

It is a shame that many evaluate cables in a vacuum attached to nothing merely by specs. They don't appreciate the interaction with other components and the radio and power environment in which they live.

The funniest (actually saddest) assertions are those based upon implementing switch boxes for comparison - which totally alter the results! They worry about contact resistance and don't have a clue about measurable interactions.

Feanor linked to one of Rod Elliott's pages about cabling that exhibited profound ignorance. Basically, he said you could compare cable audibility by splitting the output of a source using a Y-adapter into different inputs. Using my trusty capacitance meter, I find that doing so combines the capacitance of both cables at either end! Guess what? There's no difference! You just have to laugh at guys like this who have so little understanding of system interaction - much less introducing uncontrolled variables into their "scientific test". :)

Other than his ketchup comparison being a bit silly, he's basically just a cheapskate. Might that not be somewhat pertinent here?

I will never spend thousands of dollars on cables, not only because I'm retired and on a fixed income, but because, deep down inside, $3,600 for a single 1-meter cable stikes me as flat-out ridiculous.

None are designed for EMC issues.
I'm a pragmatist. The world is what it is. Cost controlled at every turn, too.



Why would you say that? All I said was, I got a red x in a box where you linked a picture.
Sorry, I thought it would be helpful to explain why you weren't getting the image.


I've duplicated the valhalla.
Matching three metrics, perhaps. I continue to disagree with the notion that is all that matters when used in real world systems.


I did not say that lower effective dielectric coefficient, or faster prop velocity was better. Nor, worse. But different.
Ok. Generally speaking lower EDC creates fewer interactions and phase changes than those with higher values.



What were the numbers for both cables?
1.33 vs 1.10.

You'll eventually agree with me...I'm patient..:biggrin5:

It does? Why is that?:frown2:

Seriously, The interaction between cable length, it's EDC, it's characteristic Z and R, all conspire with the load to modify the soundstage imaging placement accuracy. Saying such a monotonic statement as you have isn't accurate. It's unfortunately, a tad more complicated than that.

Neat. What about the other numbers?

Theory sure does look good on paper!

How do you know those are the only factors. Which one(s) have you considered and ruled out?

I think "generally speaking" is a sufficient qualifier.

On that we most certainly agree!

Length was the same at ten feet or so. Z value not published for both cables. Good question. Very similar. We're not comparing 24 gauge zip to 12 gauge zip.

It's even better when it describes a model which is an accurate predictor of an outcome.

The list is extensive. Color, height from floor, grain boundaries, 4 9's vs 7 9's, lots of really silly stuff.

How does one know effective dielectric constant without knowing the distributed L and C?? They conspire to create Z.

It would appear that you are looking for the "characteristic impedance" as I have already provided the EDC. At least according to your definitions from five years ago.

I was referring to the use of "Z" to represent impedance in ohms. Aren't you with the plan? After all, resistance is the ONLY important factor to Roger Russell. :) In that case, the answers are 1.09 /.09 vs. 1.33 / .04

FWIW, the values for my JPS cable are 1.16 / .05.

I know. What is L, C, and R for the cable?

Luckily, I am not Roger Russel..

Which is why I asked for the numbers.

and yes, vprop =1/sqr(EDC)

Z =sqr(L/C)

I know.
But confused me by asking the wrong question.



What is L, C, and R for the cable?

9.2 pF / 0.15 mH / ??? vs. 11.8 pF / .096 mH / 2.6 ohms per 1000 ft.

Will it go round in circles?
Will it fly high like a bird up in the sky?

I've already told you I do not have the resistance spec for both cables! It must be too late in the day. :)

That's a perk..



9.2 pF / 0.15 mH / ??? vs. 11.8 pF / .096 mH / 2.6 ohms per 1000 ft.
So first cable EDC 1.33 and vprop 86.5%.

Second EDC 1.09 and 95.5%.

Now the unanswered question..What is the L, R, and C vs frequency?? And I know you don't have the infor, nor does the vendor. Sigh, this high end audio crew, nuttin but anarchy...

I get the value of EDC and glad you concur with my math - theoretical goal of matching "perfect" dielectric of 1 to reduce time/phase distortion. What does the "characteristic impedance" tell you? Is .05 better than .09 or vice versa? Why?

First cable 127 ohms, second 90 ohms, given the numbers you present.

When a cable is constructed with parallel insulated conductors in a wide form factor, the magnetic field path is increased, increasing reluctance. This lowers the inductance per unit foot, but introduces susceptibility to freuqncy based changes in inductance. Proximity effect will cause the outer conductors to begin "shying away" from carrying current, and as a result, the inductance will lower with frequency and the resistance of the cable will begin to increase.

Operator error. First due to fumble fingers on calculator. Overall, I used mH as specified rather than nH. Difference in magnitude.

For the base numbers, it determines the settling time for the cable/load system. Since we're dealing with loads which are orders of magnitude lower than what the cable impedance is, the number of reflections necessary to get to 80/90% of final value will change.

The caveat with the valhalla is what proximity effect on the cable width has on the cable Z vs frequency.

Ah, ok. For numbers large enough to require me taking my shoes off, I try to repeat the calcs many times.. sometimes it works...
