Having worked in telecom for a few years now I feel confident in saying that if we can accurately transmit a very finicky digital signal over miles of plain copper you really don't need to go crazy with a low frequency analog signal traveling just a few feet. It's a bit apples and oranges to be sure but I'm just glad that I never spent too much on high end wires.

Well you see, the audio signal is very delicate and will completely change with every property change to the system no matter how minute. Cable is just TV and phone lines are just for voice; it doesn't matter what you use for those.

This is part of what I find so confusing about head-fi, it's not really an insular community of people who spend far more money than they should on random audiophile crap, for the most part it's just people who like headphones and listening to music. For the most part it's so normal that it really blindsides me when you see someone who puts spikes on the bottom of his Mac Mini to reduce vibrations because he thinks it makes the music sound better, and then everyone just seems to agree with him that yes this would work why wouldn't it boy there's nothing weird about this guy.

It feels like having a conversation with someone and they're nice, maybe a little too in to some hobby, then BAM they start talking about how homosexuality is a choice and you shouldn't have sex before you're married and AIDS and Obummer and liberals and all that stuff and you can never look at them the same way but you also never would have seen that kind of crazy coming at you -- this did happen to me in real life by the way, can't be friends with that guy anymore.

Videophiles are an entirely different echelon of crazy, but at least there are standards for video calibration. Most of them also go nuts for sound systems too so there is cross over. I have a semi custom installation and went out of my way to find someone who had reasonable, sane ideas and understood the concept of 'good enough' and was willing to patch the drywall holes he made when doing the work.
I still can't believe that ABX is bankable over there. At least a few of the threads I have seen mention your brain as needing to adjust to new sound signatures in addition to the mythical "burn in."

I have a friend who just got a 55" 3D TV and needed an HDMI cable. Rather than buy one for $5 from Amazon, he just couldn't wait and paid $40 for one from BB.

Of course, he always tells me the specs of his TV like it makes a difference to me (it doesn't). I was not particularly impressed with the 3D effect.

I mean, the idea of cables or electronics improving after a burn in period is ridiculous, but it's seems reasonable ( to me ) that speakers and headphones may not sound at their best after being sat in some warehouse for who knows how long.

The booklet that came with my Monitor Audio speakers recommends that I wire them out of phase and position them facing each other for 12 hours before installing them properly.

I've tried to look further into it but it's an exercise in futility, trudging through pages of audiophile wank is funny for a while but it's such a mindfuck.

If its something with a moving part, then performance will absolutely change after X hours of usage. Headphones will be something it's most noticeable on; midrange treble can be massively lacking until they've been played a little while. It's not subjective either, reviewers occasionally measure it.
However, the audiophile will go further, claiming one needs to burn them in for 150 hours of sine waves, followed by 72 of white noise, yadda yadda. Of course, only they can hear the effect because their ears are special. Most tend to normalise after about 10hrs of normal use, or so. If cables did change characteristics with use, it would be after 10's of 1000's of hours. They don't, more to the point.

People who burn in HDMI cables are a special type of subhuman whose only larger concern in life is what the chemtrail weather is like today.

Depends how long you define as a long time. Vintage speakers will suffer from rotting of suspension material, particularly foams. Speakers should be considered as an item with moving parts and overhauled appropriately.

Every material on earth has a certain degree of elasticity. Unless you're overdriving your speakers like hell, the vibrations aren't going to shake the suspension materials apart, unless they degrade chemically (rot or whatever).

Bob Crites has this writeup on speaker break in. I take his opinion as fact.

quote:

Frequently Asked Questions
Some ramblings of mine will appear below. Some of this is controversial. You can get opinions on the internet telling you whatever you want them to tell you. The opinions below are mine using my logic and my testing.

QUESTIONS AND ANSWERS


Q: Do components have a break-in time?

A: Some do and some don't. Capacitors would be a definite NO. Let's look at this one a bit.

You have new good quality capacitors installed in your crossovers. Capacitors have exactly two qualities that effect the sound of your music that goes through them. Those are capacitance (what we use them for) and ESR. ESR is the sum of all other qualities of a capacitor other than capacitance expressed as an Equivalent Series Resistance. ESR is a bad thing. Good caps have ESR so low it is barely measurable, on the order of a couple of hundredths of an ohm. ESR is made up of stuff like the resistance of the leads and their connections to the foil inside the capacitor or stray inductance or dielectric absorption.

So, we put our new caps in the crossovers. These new caps are right on the capacitance value the design calls for and the ESR is almost unmeasurably low. What exactly of these two qualities do you expect to change with break-in? And if either of them changed, why would you expect the sound to get better since the only way they could change is to go away from the "perfect" values they had to start with? I hope any caps you use in your crossovers are good enough that they do not change at all for many years of use.


Q: But my speakers sound so bright after putting in the new caps that I have to hope they change with break-in. In fact I am pretty sure they are getting better as I listen longer. They must be changing.

A: Sounding brighter is a good thing. That means your old caps were really bad and had high ESR. That high ESR had the impedance all upset on the crossovers and you had the drivers all trying to play at the wrong frequencies. Also, the high ESR was directly attenuating the high frequencies. Now with the new good caps, the frequency and level relationships are back to where the factory had them when the speakers were new. The fact that you think they are changing now is because you are getting used to them sounding like they should. The break in is occurring but it is inside your head instead of inside the speakers.


Q: How about break in time for wires and interconnect cables?

A: None


Q: How about break in time for drivers or new driver diaphragms?

A: Yes, and depends on the size of the driver. Tweeter diaphragm probably break-in at a matter of seconds. They are very low mass and move very little, so any break in would happen almost instantly. Probably happened when the factory tested the diaphragm after manufacture.

Midrange are a bit bigger and have a bit more mass. Break-in is probably on the order of minutes with these.

Woofers would take the longest. I think that break-in on a 12 to 15 inch woofer would be less than an hour played at pretty good volume using music with a lot of low frequency content.


Q: Do different capacitors sound differently?

A: Good caps all sound the same. Let's define that term. A good cap has the value of capacitance we need and has very low ESR (I defined ESR earlier). A bad cap has either the wrong value of capacitance and/or higher ESR. If we compare a good cap to a bad cap, we would probably hear a difference. If we compare two bad caps, they would also probably sound different. If we stay with good quality polypropylene caps, we likely meet the two qualities we need....right value of capacitance and very low ESR.


Q: You say to use a good quality Polypropylene cap. Why not use the cheapest ones? There are cheaper caps than the Sonicaps you use.

A: In testing caps, I look at ESR as a sign of quality in manufacturing. When testing some of the cheaper polypropylene caps, I see low ESR, but ESR that varies between caps more than I like to see. I would rather see all the caps measure about the same and very low in ESR. For instance one popular brand of inexpensive polypropylene caps I have tested varied from about .02 ohms ESR to around .06 ohms ESR in a batch of ten caps. Now .06 ohms ESR is still a good cap and I consider that to be very low ESR. But, since there is a variation between the caps, that makes me question the quality of the manufacturing process for those caps. And since ESR increases with age as a natural part of the aging process, I consider that starting out with very consistent values of ESR when new, is likely to result in the caps staying good (with low enough ESR) longer.

Testing like that, led me to go with the Sonicaps. They were the most consistent of the caps I tested. The manufacturer of these caps tells me that he thinks they may last 50 years. That is much longer than typical caps have lasted and that will be something for others to verify. I won't be around that long and neither will the guy that manufactures these caps. But I do like the idea that he was designing in qualities he thinks would make them last longer.


Q: How do you measure ESR in caps?

A: That takes an instrument made to measure ESR. I use a B&K Model 885 LCR ESR Meter. I also use the Kelvin Clip leads with that. Cost is about $600.00 for that meter with those leads. That is the least expensive meter I know of that will really give accurate measurements of ESR.


Q: I have heard rave reviews of Paper in Oil caps for crossovers.

A: Pure audiophile garbage. All the PIO caps I have tested have very high (around 0.5 ohms) when new!!. I call those bad caps no matter how much someone charges for them. They have that "warm" sound, people say. Warm then is defined as the high frequencies being rolled off.


Q: What do you think of using "bypass capacitors" in a crossover circuit?

A: Not much. The theory is that you can use cheaper caps in the crossover circuit and then use a high quality cap of about 0.01uF to "bypass" that cap and impart the "goodness" of the 0.01uF high quality cap into the circuit counteracting the "badness" of the lower quality crossover cap. First, I really don't like that someone in the cap selling business hijacked a perfectly good electronics term (bypass capacitor) and decided to redefine it's meaning. A bypass capacitor in electronics is a cap used to bypass AC around a DC circuit. Now it is being used to describe this idea of bypassing AC around an AC circuit.

Anyway, at the audio frequencies we use in crossovers and the impedance of the circuit, none of the frequencies we can hear would actually go through that .01uF cap. So, what could that cap do to the circuit? I think the obvious answer is "nothing". Good news is that this would not hurt anything. I have never heard any reasonable and coherent explanation using real electronics terms of how this cap could help anything. I think the whole idea was created to sell more caps. Yes, I am aware that JBL used this trick in a few speaker crossovers for a brief time. But they were selling speakers. Some speaker manufacturers set up their speakers in certain ways just because some they sell them to expect it. Like bi-wiring perhaps.


Q: How do I know if it is time to replace the caps in my crossovers or replace the crossovers?

A: If the caps are over about 20 years of age, it is time to replace them or replace the crossovers. The caps are the main wear item on the crossovers, so a rebuild replacing the caps gets you most of the gain you could get. Replacing the crossovers completely, gets you some more gain because everything would be new and higher quality than the originals.

Also consider that for some speaker lines, parts for the crossovers were of lesser quality to start with since this is a place where costs can be cut and there is not an immediate hit on the quality of sound from the speakers. This applies to the non-heritage lines of Klipsch speakers. We see that in lots of those, the quality of the parts, especially the capacitors was not up there with the quality we see in the Khorn, Lascala, Cornwall 1, Belle, and Heresy 1. So, it is good to work on those earlier than the 20 years I mentioned earlier.

No, that's actually pretty much in line with standard audiophile reasoning. According to them, science and measurements are not to be trusted because your ears are much finer instruments for determining sound quality than some fancy piece of test equipment.

Apparently, measuring sound takes all the 'feeling' and 'emotion' out of it.

Detachable headshells = one more connection. Connections are bad.

In professional gear this is actually a problem since the headshell connectors tend to get dirty over time with people swapping carts/headshells all the time (and licking the loving connector instead of cleaning it). Of course, they have to be detachable to be useful so...
