When audio signals pass through a capacitor they sound different depending on which kind of capacitor is in use. Why? And check out our newest KZfaq channel kzfaq.info/love/SObrk2ePzVwHgCtxzHU22g Octave Records.

As a retired analog microchip designer with 35 years of experience, I have a good practical knowledge of capacitor characteristics. Caps have three basic electrical characteristics: capacitance, equivalent series resistance, and equivalent series inductance. Depending on the circuit in which the cap is used, one or more of these might be completely negligible. Film caps have much lower series resistance than electrolytics, but most of the series inductance is in the leads, so there is not much difference between the two types. In audio circuits, resistance and inductance are almost always negligible because the frequency of operation is so low. At audio frequencies, series inductance is practically zero. Series resistance along with the capacitance results in a tiny phase shift of the audio signal, but it's not at all clear that such tiny phase shifts are audible. Rather than providing an explanation, Paul, all you've done is *declare* that film capacitors sound better than electrolytics. To provide an explanation, you would have to deal with the capacitor characteristics I described above, by *showing* how an audio signal is altered in a way noticeable to the human ear. For example, tube amplifiers sound different from transistor amplifiers because tube characteristics are different from transistor characteristics. Almost all audio amplifiers provide gain by using a feedback circuit to control distortion. Tube amplifiers have inherently much lower gain than most decent transistor amplifiers, and end up having much higher distortion, mostly in the odd harmonics, than transistor amps. It's that distortion that is actually pleasing to the ear, and for poorly known biological reasons, "sounds better" than an undistorted signal. That's the sort of explanation you would need in order to explain why "film capacitors sound better than electrolytic capacitors. To be thorough, you'd have to provide a representative circuit schematic of some amplifier and explain exactly why using one type of capacitor in one location produces an audio signal that "sounds better" than if using another type. Also keep in mind that electrolytics are not used very much in audio circuits (except perhaps very low frequency bass circuits), but almost exclusively in power supply circuits.

And Alan, dielectric absorption might be the biggest factor. Yes ESR and ESL are important, especially for bypassing and circuits that pulse (switching regulators) but DA is the most likely differentiator. Agreed, lead inductance has no bearing at audio freq. Pease wrote articles about this, calling it a memory effect. Also a changing voltage and/or bias voltage across a cap influences the charge available which changes the capacitance. This might be a minor effect.

@@philipwebb960 They produce both. Clever designers use staging and topologies which tend to cancel even harmonics, so in practice it's more of a myth than reality, that tube circuits produce mostly even harmonics. But considering the overall frequency distribution of distortion harmonics, it is generally true that tube circuits produce more energy in low-order harmonics and less energy in the very high-order range, compared to class AB transistor circuits, for example.

Different caps result in different styles of leak, just like transistors and tubes have different clipping and compression. ,,,, but i could be trippin.

the shortest answer to the title is ESR and tolerances. Two years back I visited a web page that went in depth talking about tone caps, there were even audio samples. You can have two capacitors of different types with the same exact Farad and voltage and the tonal differences are due to differences in tolerance and equivalent series resistance.

In short: some caps have more electrical resistance and unwanted inductance than others which could emphasize certain frequencies and diminish others and cause phase shifts. Electrolytic caps have relatively high internal resistance because the electricity passes not only thru metal but also thru this paste with water and salts, which doesn't conduct perfectly. The chemical reactions inside can also create tiny tiny gas bubbles which when created and vanish create variations in capacitance and resistance that manifest as noise. Because of their build with rolled up foil, they tend to have more inductance also which makes them better suited for low frequencies like filtering the 50/60 Hz out of line voltage. Now if these things are built with great care, these effects are smaller than with cheaper ones. Still, generally one would put a non-electrolytic cap in parallel to short any radio frequency interference.

It's simple ac LOW FREQ AUDIO electronics Paul, not rocket science. C=ak/d & xc=1/2 pi fc, ESR= ESR=DF*Xc=DF/(2* π*f*C. If you as a "HI-END" source buy quality parts; COTS, ISO 900X and screen them properly then there should NEVER be a CAPACITOR failure in your boxes if the design passes muster. Caps, if made properly have similar finite lifetime as OTHER solid state electronic. Paul is a BS artist. Really, at Paul and his competitors prices you should be getting milspec, ever hi-rel traceable products. Hi-End audio thrives on fear/ ignorance. Fear you say?

@HighestRank
@HighestRank 6 жыл бұрын
powertothebauer in short (pun intended), your unwanted motor interferences are A/C signals and are passed (shorted) through the capacitor in a rather brute force way: parallel-connected to both inputs of the DC motor. BUT for speakers, the connection is in series, like a paper dolls_chain holding just their hands, and so imagine one of the dolls is very little so she simply cannot stand to be shaken too hard with a large-duration pull, but indeed does very well when transmitting little alternating waves through herself. The little waves are high frequency because the speed of electricity must always move at a fixed speed throughout any conductor. That is what those formulas tell us. Why it wasn't put in simpler terms for an undisciplined hobbyist- well it is not your fault for not understanding because the electrical properties of motors are not externally apparent. They're what we consider black boxes of a sort, that nobody knows how they'll react until they're probed by meters or carefully connected. I suppose just that you're not careful because the manufacturer specifies a value and you simply throw it on without paying much attention. No big deal, we experiment more is all, but we also realize that DC voltage is not going to fry up your speakers if the current is next to nothing. Lots of other components that would be fried up by DC are actually fed little amounts of DC in a technique that is called biasing. Think of chip biasing as the old vacuum tubes being warmed up before they could start working, except this DC biasing has to be continually applied because of other characteristics. Of course the chip would fry up with a high bias-current, but resistors and especially capacitors block that from happening, which in the latter is related to how low frequencies behave more like DC while INSIDE any component. Clearly pure DC does not alternate, but AC signals can be biased to the point where the most negative troughs never reach 0V, and look on a scope like pulsed DC. You're probably only familiar with balanced inputs and 0V grounding, not these signals that legitimately 'float' above a 0V ground.

I do agree with Paul on his views of capacitors. From some of the comments I read, he may not have explained it to a deep enough level. He did not talk about dissipation factor of the dielectric. Capacitors are not perfectly efficient devices, electrolytic capacitors will tend to hold a small charge even after being shorted out. Electrolytics have a ripple current rating, series impedance etc. I personally like using film capacitors whenever space allows, because they sound better than electrolytic caps. I have not tried the super expensive audiophile film caps to see if they are substantially better than the run of the mill film caps.

Personally, I feel the “What is a capacitor?” could have been explained more clearly. At it’s fundamental level, a capacitor is an analogue electronic component capable of storing and releasing an electrical charge. The rate at which it can store and release that charge is determined by its characteristics. Some graphics would also helpful. I graduated from university in Electronics and Communications Engineering. Power supplies and audio circuits were a big part of my course. For people who don’t know what a capacitor is, the video isn’t helpful.

Summary: "capacitor is _any_ two conductors that are insulated from one another...dot!" and the various electrical properties associated with the capacitor depend on myriad of physical factors. Like the surface area of the conductors, insulating material, distance between conductors etc. etc. etc... And these cause myriad of effects that an ideal capacitor seen in circuit analysis doesn't have such as polarity, unwanted series resistances, inductances... susceptibility for DC-bias etc. etc. and all of these effects can and probably will distort the signal that's passing trough the capacitor if it's in series with the signal. That's why we have gazillions of different kinds of capacitor technologies and they all have their places and prices. But all in all it matters only if one can measure (or if you're an audiopho-- audiophile, hear) the difference.

I will answer, more expensive capacitors usually have a lower series resistance(ESR), large capacitance values(in thousands of uF) are usually electrolytic, these however have poor leakage, so better designs use low leakage types such as polypropylene-however they are physically large and expensive. There are also other factors that determine capacitor quality aligned to the application it is used in too, but in a nutshell ESR is arguably the most important in general in audio. Paul is right about putting a film capacitor in parallel with an electrolytic to lower ESR, however that does not prevent leakage, so a high end design should try to avoid electrolytics. Although if the design is using a linear power supply you really cannot avoid using them on the smoothing section; replacing them with film would be very expensive and you would end up with a box full of capacitors to make up the 100,000uF or whatever you wanted to smooth the DC with. Also note that the better capacitor manufacturers have better noise immunity by better plate design, using higher quality electrolites, and also lower ESR lowers thermal noise. Now why do they sound better?..well thats hard to answer as capacitors are used in many different apps in an electrical circuit; dc blocking, smoothing, filters and so on. So refer to my first paragraph to cover all apps.
@availablenowonwards

THE REASON IS, ESR OF CAPACITORS - See the explanation given below if needed. 1. Capacitors are meant to block DC and to pass AC. 2. If the frequency of a signal (or current) is Zero Hertz (the unit of frequency) - it is DC. And if the frequency is One or more Hertz, then it is AC. 3. We use capacitors with suitable values to block or pass the some frequencies - Higher capacitance values can pass low-freq signals and vice-versa. 4. The electrical audio signals are AC, varies somewhere between 20Hz to 20,000Hz - Here, the lower frequency signals are supposed to be handled by the Woofers/Sub-Woofers and the higher frequency signals are by Tweeters and the mid frequencies are by Mid-Range speakers. We must pass only the intended frequency range to the respective speaker type, otherwise, it may sound strange. 5. The mentioned "different sound quality" is mostly observed on the low frequency ranges - here reveals the actual problem. 6. All capacitors do have ESR (equivalent series resistance - it is an AC resistance, it decreases with increase in frequency) and this parameter will offer some sort of blocking to the lower frequency signals which pass through it. 7. Since the low frequencies needs much current to be reproduced effectively, the current limiting by ESR will be a villain (bass may not be as deep as expected, with lack of expected current) 8. Also, in crossover networks, we use capacitors to bypass the unwanted frequencies to ground and to pass only the wanted frequencies to output, but, with this ESR, those will not be passed/bypassed effectively, and the speakers which are connected to the output will sound different. 9. Polypropylene capacitors (the small yellow one shown in the video) are at-least 10 times better than electrolytic caps in terms of ESR and hence those are called "audio-grade". (Any caps with lower ESR can be audio-grade in fact)

After caps changing , the tweeters come to life and the speakers have a very pleasant sound.

Not just cheaper parts, but different TYPES of capacitors are made for different functions. Use a capacitor in the wrong application and you can introduce massive amounts of distortion, even among the same QUALITY caps. Cannot simply substitute one for another.

I have a 7 band graphic eq that I'd like to change the lower frequencies. Is it possible to change the capacitors in certain frequencies to get your desired effect? For an example, if I want to change my lowest frequency of 100 hz to 50 hz and the second frequency is 125 I'd like to change to 80 or 85 hz. Also, how do I determine the slope at which the frequencies roll off? Thanks for any help you can offer.

the capacitor symbol is theoretic, fictitious , but essential to understanding the electrical behavior of an ideal capacitor . A real, physical capacitor has parasitic elements such as ESR and inductance that change the behavior of a real capacitor when compared to its theoretic behavior. A real capacitor becomes a resonant circuit at some high frequency due to the parasitic inductance. A 100uf electrolytic will resonate with its parasitic inductance at 10khz. In order to maintain the effects of 100uf at frequency above 10khz it is necessary to add a mylar capacitor of say 0.1 uf in parallel which will effectively bypass the 100uf at frequencies above 1khz. m.shen

Capacitors can introduce audio distortion through variations of ESR or capacitance with the instantaneous voltage and current across the capacitor. Consider a high-value ceramic capacitor in a basic 1000hz high pass filter. A 100hz signal will be greatly reduced, but the capacitor value will vary up and down due to the 100hz voltage across the cap. This will introduce 100hz modulation on higher signals, strongest 100-2khz. An X7R ceramic cap's capacitance can fall 50% at it's rated DC voltage vs 0VDC. ESR of an electrolytic capacitor is far from an ideal resistor. It is after all passing a signal through a chemical bath (electrolyte). Lots of opportunity for diode-like effects. Dielectric absorption has been suggested as a factor, but it generally occurs on a time scale of seconds or longer, outside the audio band.

Capacitors will pass alternating current above a particular frequency, and block direct current. A capacitor essentially stores a static charge that the alternating current signal alternately charges and discharges. This is how is passes on alternating current - because the stored charge on one side of the capacitor creates an exact opposite charge on the other side of the capacitor. The amount of charge (in volts) that can be stored dictates the amount of alternating current that can flow. Capacitors and inductors in combination form what is called a resonant circuit. Resonant circuits form the basis for all tone controls and all analog signal filters of any sort. The different types of capacitors - made from different physical materials - have different properties. Among those properties is also a degree of inductance. And the different types of capacitor have different amounts of inductance. Interestingly, inductors also have a degree of capacitance. The trick is to combine inductors and capacitors in such a way that you get the right amount of capacitance and the right amount of inductance in resonant circuit for what you need. An inductor is similar to a resistor, but is frequency dependent. A resistor inhibits the flow of direct current, and an inductor inhibits the flow of alternating current above a given frequency. Thus, a capacitor filters out low frequencies, and an inductor filters out frequencies above a particular point, and what you get is a band of frequencies that the resonant circuit will pass. Some inductors are just resistors working with an AC signal, and other inductors are coils of wire. Transformers have an inductance and a capacitance rating.

When I was a teenager, in 1981, a guy working for the Electronics magasine Radio & Television did a blind test on a bunch of audiophiles. He put some capacitors considered "bad" along with a few low slew rate 741 op-amps (and some other "bad" stuff) in series with "high end" audio equipment at "line level". Swithed them in and out several times. None of the blind folded "golden ears" could determine when the 741 or the "bad" capacitors were included in the signal chain or not. Since then, I lost interest in this expensive quasi religion and started concentrating fully on the music itself. That said: There are also audible differences, of course! Speakers sound very different, for instance. So did cassette recorders. Varying damping factors in power stages driving bass speakers are indeed noticeable. Some recordings from the 1970s have terrible distorsion in the treble, and so on. (Possibly that famous "TIM", transient/dynamic intermodulation due to too hard feedback on too many or slow amplifying stages.)

@patfurlan

what he was driving and did not clearly define was that the electrolytic is less efficient in passing audio signals but better at storing a large charge. Audio passed through an electrolytic gets cloudy or dark in the upper frequencies as the bulky materials take longer to charge and discharge and don't track the high frequencies as well. The small signal cap with its thin plastic insulator and super thin foil layer reacts more smoothly and efficiently at high frequencies. Otherwise an excellent presentation. think of it this way you might wear size 10 shoes, but a construction boot and a running shoe will behave differently in walking and running dynamics even though they would both fit you. The smaller lighter materials respond to ac changes faster and with truer fidelity.

At higher voltages electrolytic capacitors go bad after a few years or even decades even when they are not used. Polypropylene capacitors do not have this problem because they have an indefinite shelf life. They also have less ESR than electrolytic. This makes them better for plate voltage power supply filters and this is why I use them in my vacuum tube amplifiers, especially the 1000 Volts I use for my 833A SET. You can get them rated at 2300 Volts which is a comfortable over-design safety for this. I see electrolytic capacitors used in vacuum tube amplifiers costing 5 figures or more and this is why I prefer to make my own amplifiers.

Hi Paul. Off topic question here, and one I assume you get asked a lot. I remember back in the late 70's a friend of a friend had a system comprised of homemade bookshelf speakers and what I would assume was a class A amp/receiver and turntable. We played a lot of vinyl, (rock). Volume was never a consideration. The sound "filled" the room, and you could hear every individual instrument. To this day I've never heard anything that could compare. I have always aspired to recreating this sound, but nowadays with most sources being digital, I have never really come close, (mostly due to budget constraints). I recently came across the Dayton Audio APA150 for under $160. It would be powering two Polk 200TSi speakers. Media sources would be digital so I am currently using a SMSL SA-50 amp paired with a Signstek HIFI USB to Coaxial S/PDIF Converter Decoder Mini USB DAC PCM with 2704 chipset, (I also use an audio EQ extension on my PC to accentuate the highs, mids, and lows). What is your opinion of the Dayton Audio APA150 vs. say... the Emotiva BassX A-100 , and could your offer an alternative DAC? Am I at least headed in the right direction?

Two caps of the same type and same value must sound the same. The more expensive cap might last longer but when the two caps are fresh out of the box they necessarily must sound the same. Different sound indicates different values and if nothing else caps must perform to the stated value regardless of price. Differences in cap style make different sound.

Not really. The more expensive capacitor might be made with better quality materials than the cheaper one of the same type and value. That may result in smaller non-linearities (the change in capacitance with applied voltage) and that is the key factor in how a capacitor "sounds". With electrolytics, even if they are being used just as smoothing capacitors, a better quality one is likely to have a lower ESR than a cheap one with the same capacitance. That might mean a noticeable increase in ripple voltage with the cheap part, and that can cause clipping on loud signals. You'd certainly hear that.
