The following are some HIFI metaphysical contents that I have heard, each is more mysterious than the other

1. Whatever is placed under the CD player will make the sound. Later, it was extended to the point that whatever is placed under the speaker will produce the sound. (What if it’s padded with dog poop?) An audiophile once told me that if a sponge is padded under the digital mixer, the sound will be very soft... (Later I told my music professional buddy, remember, wear high heels. The sound produced by flat shoes is definitely different...)

2 The sound produced by the computer case is different when placed horizontally and vertically.

3 The same Wav file has better sound quality when placed on a Seagate hard drive than on a Western Digital hard drive. Even if they are on the same hard drive, the sound quality will be different if it is placed on the C drive and on the D drive.

4 The audio cable has a direction and it will not sound good if it is connected backwards. Not only audio cables, but power cables also have directions. Replacing the power cord with a good one can improve the sound quality. If there is a magnetic ring on the power cord (called the "Lord of the Rings" in metaphysics), the sound quality will be even better...

5 There is something called "CD Divine Oil". After applying the CD, The sound immediately increased by a few decibels (I'm dizzy, Viagra?) Then there was the CD magic pen, just draw on the edge of the CD, and immediate results were achieved... Later, there was the CD magic film, which was effective as soon as it was applied (for me)

6 If the CD is frozen in the refrigerator, the sound will become better. This is nothing unusual. Nowadays, the strong light of the camera flash is used to illuminate the CD. The sound field of the illuminated CD will become wider and the sound will increase by 3 decibels. If you think "shining a CD with a strong light" is new, then you are really old-fashioned!

The following is a reposted article about metaphysics: Yesterday I saw the following content in the 2005 Issue 10 of "Tube Amp World": 2005 Hong Kong Hi-Fi/Hi-Vi Exhibition, purchase price 100 The "JSMR" magic chip will be given for every 1 yuan ticket, as well as a selected CD recorded by LEO and a Hifi dragon and tiger list mentioned the JSMR magic chip. The description is as follows: The JSMR magic chip is as thin as a thumb, as long as it is placed on the CD player, it will It can instantly improve CD sound quality by more than 20%. The editor-in-chief of this magazine believes that this is the most mysterious and effective audio accessory he has used in recent years. He hopes that audiophiles will become addicted to Hi-fi after using it. (The author comments, if this thing is really effective, I think every manufacturer of CD players will buy it in batches, and the cost is extremely low. Isn’t it a big cost savings? Why bother to study the wiring and component matching? It is really common. The greatest irony in the world! ) Similarly, the audio writer "Hi-fi Bible" wrote about how to produce beautiful sound. If you want the system to have a smoother sound and a clearer outline, you need to put a loudspeaker on the top of the machine. A small piece of Hangzhou silk would also be good. If you want to make the sound a little more shiny and textured, putting a pin on the surface of the machine can enhance the effect. Similar things include placing a slingshot for more liveliness, bounce and overtones, placing a concave rosewood seat on the CD cover to increase high-frequency details, airiness, and charm; placing wrinkled paper or cloth at the bottom of the player can make the sound brighter. Mellow and smooth. Every time I see this kind of thing, I always feel filled with emotions and resentment.

I don’t know how they came up with these pseudo-sciences. What is the theoretical basis for these things? Do they dare to listen blindly to verify the tricks they said? Publicizing their so-called secrets openly in books and magazines is really a misunderstanding of their disciples. Whenever I see similar articles, I always dare not take a liking to the author of the article. The following quotes some excerpts from the article "The Myth of Audio" to refute the above pseudoscience: "For example, many friends in many magazines talked about "the sound of adding three copper cones under the CD player is the same as that of the original wooden cones. no the same! " and " After using a few rubber feet imported from the United States under the amplifier, the sound is much better! " and so on (omitting some adjectives such as clarity, transparency, sweetness, and imagery). I admit that I have little talent and knowledge and cannot understand the truth, so I am sincerely convinced, full of praise, and admire the ears of all enthusiasts. Falling to the ground.

However, after reading many such articles, I discovered that all audiophiles only describe the changes in sound, without any theoretical explanation. Okay, even if you haven’t summed up the theory yet, you have to let the facts speak for themselves, right? Friends who hold this view, have you ever done a blind listening experiment? Invite a few so-called "golden ears" to sit in a listening room. The speakers are in the listening room, and the amplifier and CD player are in another room. Play the same track, and randomly decide whether it is on the CD by tossing a coin. Put something under the machine and amplifier and try 100 times to see what the accuracy of each position is. If it is only about 50%, I can do it by just guessing instead of listening with my ears. If you think 100 times is too much, 30 times is fine, but not too few, otherwise the chance will be too great. If any expert has made any changes to the equipment and wants to write about his feelings, I hope the article will have the following points:

1. Measures taken

2. Changes Principle (that is, why this change will affect the sound quality and what kind of impact it will have)

3. Description of the sense of hearing

4. Scientific proof of the experiment.

No two leaves in the world are the same. Any change in conditions will affect the sound. Even if you just add a few pyramids under the CD player or amplifier, at least it will change the sound in the listening room. Space state, but a very important question is whether this change can be distinguished by the human ear.

The speaker is a combination of a speaker and a cabinet. The speaker is the sound source, and the cabinet is the sound chamber. Different tripods or footpegs are different in contact area, orientation and production with the speaker cabinet. It is understandable that differences in materials affect the vibration of the box and thus the sound. As we all know, the singer's body is a musical instrument and a big "speaker", but if any friend says that the "sound effect" of Pavarotti's singing is different when he wears leather shoes and cloth shoes, and can hear it, I dare not Agreed.

If adding three pins under the CD player and amplifier can really improve the sound quality, why have I never seen manufacturers directly sell CD players and amplifiers with three feet? It seems that no manufacturer sells footpegs as standard equipment for CD players and amplifiers?

I am afraid that it is because I have too little knowledge, so I went to ask some equipment store owners for advice. They told me very cautiously: "I dare not say that there is no such thing, but 99% of CD players and amplifiers are. It has 4 feet. The most common piece of equipment we have seen with 3 feet is the iron pot used for cooking. ”

Some friends also said that the feet are added under the CD player to prevent shock. Judging from the current knowledge, household CD players only need to be placed on a basic level surface, and no anti-shock measures are required at all (unless there is an earthquake or the CD player is doing strenuous exercise while playing music). The optical disk drive of an ordinary computer is in a metal box of ordinary workmanship. There is at least one power supply fan and one CPU fan rotating in the box, and at least one hard disk is rotating. CDs working in such a "harsh" environment -rom, when the data of the entire disk is read, there will be no error in one byte, which shows that the optical head does not require high requirements to read the data. Some friends pointed out that computer CD-ROMs and CD players have different error correction methods, so the quality of the CD player's turntable has a great impact on the sound quality. I have not done any experiments and have no right to speak nonsense, but has anyone found a white paper on audio CDs to see what the error correction principle of audio CDs is? Under what circumstances do bit errors occur? What is the specified bit error rate? Can it be detected by human ears?

I am a rough person with no education, and I really don’t understand what the so-called “time base jitter” phenomenon of CD players is all about.

Isn't it just an inability to provide data to the decoder at the right time? What is the time frame of the error? How many milliseconds? Or how many microseconds or nanoseconds? How many nanoseconds of error will result? What is the jitter of a top-end machine? What is the jitter of an ordinary machine? Are there any specific numbers? Is it that current science and technology cannot solve this problem, or does the manufacturer simply not want to provide a cheap solution to this problem? Of course, it is impossible for most audiophiles to conduct tests according to this standard at home, but cutting off all channels of psychological suggestion, sitting there blindfolded and listening to the music, and finding a friend to use several sets of wires to change back and forth (or even pretend to change the wires) , and just make some sounds), listen to it a few times to see if you can hear the difference between them. It is not difficult to do, right? I personally think that if a listener cannot hear the difference between several pieces of equipment, then there is no difference between these pieces of equipment for the listener and just choose the cheaper one. There is a difference, and it only counts if you can hear it.

Some friends are very enthusiastic about fever. They usually read magazines or chat online every day. They don’t have many opportunities to actually come into contact with expensive equipment. Even if they come into contact occasionally, they rarely have the opportunity to compare at the same time. Once After having an "intimate contact" with a certain piece of equipment, he was "astonished" and talked about his feelings everywhere. It should be noted that the feeling of listening is not only related to the equipment and listening environment, but also has a great relationship with the listener's emotions, cultural accomplishment, aesthetic taste, physiological conditions, etc. If it is not compared on the spot, then it is very important to determine whether the feeling is affected by other factors. It’s hard to say. Commenting on equipment you are not familiar with is like commenting on someone you are not familiar with. It is inevitable to make mistakes.

Friends who often come into contact with computers should have this feeling: It is good to have an expert around you, but having a novice-level computer enthusiast is a very scary thing. Their characteristics are that they are passionate and have a strong desire for knowledge. Most of their knowledge comes from books, newspapers and magazines. They have a lot of so-called "secret skills" in their minds. They have deep feelings for high-configuration machines, even to the point of worship. When I see anyone's computer, I feel that there is still room for optimization. Not only do I talk about it, but I also have the courage to do it. The consequences are often beyond everyone's expectation. If you ask them to assemble a microcomputer for you, nine times out of ten it will be a combination of his "dream lovers". As for the actual effect, the key depends on luck.

This phenomenon also exists in the fever community now: many enthusiasts are enthusiastic and willing to help others, and they are not "trusted" by someone. There is only one thing: lack of practical experience, lack of comparison, and unobjective views. It is the mantra of these friends to call equipment worth less than tens of thousands of yuan garbage. From my observation, really high-level and well-educated enthusiasts are often very cautious when speaking, and they are afraid of making people laugh. Most of the people who always express their opinions casually are rookies like me (just like new drivers who are always eager to drive). Same), I wish I could publish it to the whole world. This is not only true for fever, but also for other aspects. This is why there are not many high-level articles in newspapers and magazines now.

My friend’s mother is a wine critic. The process of wine evaluation is very strict. Many kinds of wine are packaged in the same way. You can’t tell the brand from the appearance. To avoid bias, you are not allowed to eat this before tasting the wine. , don’t eat that, don’t catch a cold, etc. The requirements are very high. More importantly, they are all evaluated at the same time and by the same group of people and scored according to the standards. And after tasting one kind of wine, you should rinse your mouth with water and rest for a while before tasting the next one. In addition, you should not taste many kinds of wine in one day, so as not to affect your judgment. Of course, the personal preferences and tastes of these people will have an impact on the scores, but since there are so many people participating in the wine tasting, the special circumstances of a few people have little impact, and the conclusion is still relatively objective. The situation of wine is somewhat similar to that of hi-fi equipment. All kinds of wine have their own characteristics. After reaching a certain quality level, except that the same type of wine can be compared with each other, there is basically no comparability in other cases. sex.

Who dares to say that liquor is better than beer? Is rice wine better than red wine? ”

After writing this, I feel a little heavy. Many things are obviously pseudoscience to outsiders or sensible enthusiasts, but some people still believe them. What does this mean? It can only mean that some people have some fever. Friends have become obsessed with high fever. This is a typical "fever" for the sake of fever. If this article can awaken their normal sense of fever to a certain extent, then I will be satisfied. Note: This evil trend. , Hong Kong is the most popular. Of course, I believe that most audiophiles in Hong Kong belong to the rational group, and this article is not directed at individuals, but only at the phenomenon. Please forgive me if I offend you! Starting from me, there will be a clear sky in the audio industry. You can do whatever you want at home. Even if you put a piece of soft tofu on the CD player, the sound will become smoother. But if you use it to teach the scriptures, it will be fine. But you must take responsibility, otherwise you will be seriously suspected of misleading others!

What exactly is a fever? I think of the protagonist of an article "The Story of a HIFI Enthusiast" posted by Dan Yixuan. The guy named "Ad" is a real audiophile... Even though he only has the most rudimentary equipment and a broken speaker...

1. A "listening master" who has never been to a concert hall.

Recently, I was fortunate enough to attend a Hi-Fi equipment demonstration hosted by a famous "listening master" in the south (actually a sales meeting for a certain manufacturer's products). The master called himself Hi-Fi. -Fi has paid special attention to positioning, sound field, resolution, etc. for many years, and warned audiophiles to "practice more ear skills". However, most of the "masters" used for performance equipment on the spot were "fever disks" that were neither high nor low. - "Vocal music" such as Jacky Cheung, Tsai Chin, Big Eyed Girl, rock music such as Hotel California, and electric pianos that have nothing to do with Hi-Fi. I listened to a few pieces patiently and felt that this set of equipment The performance of pop songs, electronic music, etc. was okay, and there was no big problem.

Later, at the request of the audience, several Beethoven Violin Concertos and "Choral Fantasy" were played that were brought by the audiophile audience. " and other Western classical music records, this set of Hi-Fi equipment immediately stopped being Hi-Fi: the piano sound was obviously distorted; the "Steinway" worth hundreds of thousands of dollars in the record was downgraded several levels continuously, and it sounded like a "low-end domestic piano". "Fruit candy flavor", the violin has obvious sound coloration, which sounds good but not true. The bow of the "Guarneri" violin seems to be covered with honey instead of rosin, giving it a sweet and greasy feeling. Several enthusiasts from the symphony orchestra present shook their heads.

What’s even more ridiculous is that the left and right channels of the whole set of equipment are connected in reverse, and the violin group and the cello group have completely changed their positions. The sound field was in chaos and the positioning was completely reversed. However, the "master" had no idea and was still talking about how to accurately position the equipment. It is said that the "master" has a good ear and can hear the size of the actor's mouth: ×× is a bloody basin. Big mouth, ×× is a small cherry mouth, and you can even hear the copper content of the wire and the material of the foot nails. It is a pity that the "master" knows nothing about the highest form of music-symphony and symphony orchestra, and I am afraid that he will never enter it in his life. After passing the concert hall, how else could I have mistaken the bartender Clayderman for a romantic piano master? How come I don’t even know the arrangement of the symphony orchestra on the stage?

I am listening. During the demonstration hosted by the "Listening Master", I felt that he was very knowledgeable about the equipment. There are strings of professional terms, and I can only vaguely understand them. The problem is that the "master" has never been to a concert hall or an opera house, and he has only developed his ear skills on paper by using high-end equipment to play pop songs and rock music. , is too subjective and arbitrary, and thus makes a big joke about not distinguishing between left and right channels. The reason is very simple - it is far away from music.

2. A "folk medicine doctor" who specializes in treating "fever and difficult diseases"

An old comrade of the author settled in Hong Kong for business in the early 1980s. He returned to China to visit relatives a few days ago. The comrades were very cordial when they met. , since we had installed tube amplifiers and cannons in the army, the topic naturally fell on fever. After listening to my set of "foreign guns and cannon hybrid equipment" that was "not high enough" (Shengya amplifier, Jinlang speaker and Malan CD player), my comrades immediately gave me some "recipes" that could upgrade the equipment to three levels in a row. They claimed that these remedies were all from authoritative audio magazines and were guaranteed to be miraculous:

Prescription One: Use a brick from the Ming Dynasty old city wall in Fengyang County, Zhu Yuanzhang's hometown, and press it on the Marantz to immediately overcome the shortcomings of excessive digital sound;

Recipe No. 2: Use crystal stone foot nails No. 3 One of them is placed under the power amplifier, and one of them is placed under the transformer to ensure that the power amplifier is upgraded to three levels in a row. Although it is not as good as "Mark Levinson", it is no problem to catch up with "Golden Voice";

Recipe No. 3: Shine the CD record with a camera flash fifteen times, then put it in the refrigerator for three hours. The 16 bits will become 20 bits, and the pirated version will exceed the original version;

Recipe No. 4: Use a rubber hammer to seal the speaker Beating from back to front, bottom to top, the treble is sweet, the midrange is rich, and the bass is strong. The speaker can compete with the Bamp; W801.

Recipe No. 5: Use 60-year-old "Qingliang" military uniforms to tear into strips of cloth and wrap the wires. The sound field will be wider, the positioning will be more accurate, and the sound will be more beautiful.

The five flavors of folk remedies each perform their own duties, the emperor and his ministers complement each other, save money and energy, why not do it?

After listening to the explanatory talk of my old comrade, I was dumbfounded. My Hong Kong businessman comrade-in-arms is a close relative of the electroacoustic profession - he has a professional radio background. However, judging from the folk remedies he prescribed to me, it seems that he has gone too far and has strayed away from science.

3. Where is high fidelity?

There is an unwritten rule in the world that it is not allowed to use hi-fi when performing symphony music, opera, ballet, etc. in regular concert halls or opera houses. Any electroacoustic equipment amplifies sound, so in this listening environment, the audience hears only the sound of musical instruments, voices and noise from the stage; the noise from the auditorium and the reflection sound from all directions (less in the recording studio) noise from the audience). This is "high fidelity" in the true sense of the word. On the contrary, rock music and pop songs can only be beautified, modified and amplified through electroacoustic equipment. The deafening sound has no fidelity at the scene. Japan, South Korea, China (including Hong Kong and Taiwan) and some highly civilized countries in Southeast Asia are the largest Hi-Fi equipment markets in the world. Music lovers in these areas do not enjoy the benefit of listeners in Europe and the United States who can enjoy live concerts at any time. , some audiophiles in small and medium-sized cities, including Hong Kong and Taiwan, may never have the opportunity to "taste" the "original" "Western-style music feast" of live symphony concerts or chamber concerts in their lifetime. Most people can only "taste" it through records and equipment. "Music Can". Under the conditions of modern technology, it is probably just a fantasy to move a first-class European and American symphony orchestra or chamber orchestra home. Assume that your equipment and records can achieve 100 Hi-Fi, but at the same time you are added during playback. Reflected sound and noise in the environment, "high fidelity" has added "additives", and it is no longer possible to have the original flavor. Therefore, I believe that high fidelity is used in classical music in concert halls, opera houses, and recording studios. among. The kind of deafening rock and pop songs that are electronically amplified can only be "high-definition fake" in their live performances.

It is precisely because of the lack of high fidelity that so many manufacturers and audiophiles are pursuing it. This is the greatest charm of Philharmonic fever.

There is a very intriguing piece of Western humor: Manufacturer A is promoting his food During the assembly line, he claimed: "My assembly line is extremely advanced. If you drive a cow in through the front door and press the button, all the delicious canned beef comes out of the back door!" Manufacturer B claimed: "My assembly line is even more advanced. If you If you think the canned food is not delicious enough, you can pour it back through the back door, and when you press the button, the same cow comes out of the front door!" If manufacturer A's promotion is compared to the process of making records, from the perspective of modern technology, it is completely It's possible, but if you compare Manufacturer B's promotion to restoring music through equipment at home, it's completely impossible. That cow will never come back anyway. If it can come back, it's just "bragging", audiophiles. The pursuit of Hi-Fi is actually processing this box of beef cans. To put it more elegantly, the pursuit of Hi-Fi is just like a photographer taking pictures or a painter painting. It is the pursuit of beauty and the re-creation of art. Inside the audio fever There is both science and art, including acoustics, electroacoustics, electronics, materials science, architecture, physiology, psychology and many other sciences and related arts. Fans should be clear-headed and sensible, and study more diligently. Practice, budget carefully and keep your wallet tight, use good steel on the blade, spend the least money and get the most enjoyment, in order to obtain an "approximation" that is relatively close to the live performance in the concert hall.

4. Master some common knowledge about music and go to the concert hall to practice your ears

To pursue high fidelity, you must first know the "original taste" (this word is not accurate). The purpose of having a fever is to listen to music. You spend tens of thousands or even hundreds of thousands of dollars to buy equipment. If you listen to people smashing glass and bottles every day at home, you might as well go to the scrap collection station. The sound of smashing bottles there is definitely Hi- end level.

My experience is:

First, you need to read some music history, understand how music evolved from the mouths and palms of ancient people to the modern symphony hall, and understand each historical period. The creative background, experience and style of the masters;

The second is to understand or master the elements, texture, structure, musical form, etc. of music;

The third is to understand the famous contemporary orchestras, conductors, The specialty and style of the performing (singing) master. The above is the process of "watching music". You may not be able to understand everything, but it is endless fun to read. Through these, you can know why classic music has always been popular, and popular music has always been popular. Chao Sheng Mu died.

The fourth is to listen more live, and go to the concert hall to experience the "high fidelity". Friends who have never heard it live might as well "spend some blood" to listen to a live performance of the "Symphony of Destiny", that kind of The soul-stirring power is something that no art form can achieve. By listening to the scene, you can also very intuitively feel the timbre of string instruments, wind instruments, percussion instruments, keyboard instruments, etc., what the timbre of the entire band is, how the symphony orchestra and chamber band are arranged on the stage, and what is double Control, what is the four-control system, how do the different arrangements of the symphony orchestra achieve the overall sound balance, what are the so-called sound fields, positioning, resolution, penetration, dynamic range, etc. What do teachers in the university acoustics department often think of? Students go to the concert hall to practice their ears, probably also to let them experience true "high fidelity" through art.

5. Transform the listening environment and build your own concert hall

World-renowned concert halls and opera houses all meet the requirements of architectural acoustics, with sound absorption, diffusion, sound insulation, and earthquake resistance. It is done very carefully. Under normal conditions, symphony concerts, operas, and indoor concerts do not use any amplification equipment, and the sound transmitted to the audience's ears does not include "electronic sound".

Experts Audiophiles are often warned that a good audio system must be in a room with suitable acoustic characteristics to achieve good results. Well-known domestic audio experts, their equipment is not "feverish" enough but sounds good. The main reason is that their rooms are "feverish". ”.

If you put a set of top-notch equipment in the bathroom or cotton warehouse, it will definitely be greatly reduced. Fans spend a lot of money on footpegs and wires, so they might as well work on improving the acoustic environment of the room. This This is the advanced stage of the fever. It is difficult to change the size of the room, but hardwood floors are used, and the walls are plastered with a layer of ash. Then the position of the furniture is appropriately adjusted, and oil paintings and tapestries are hung in appropriate places, adding or subtracting one or two Decorations, etc., can get twice the result with half the effort.

6. Properly match equipment and form a "mini" symphony orchestra

Use speakers, amplifiers, and CD players to reproduce the sounds of dozens or hundreds of musical instruments. A symphony orchestra is actually impossible, but it is the dream of audiophiles. The more advanced equipment is, the closer it is to Hi-Fi. This is the truth.

But the problem is twofold. Some Some people say that the combination of equipment is good, and some people say it is not good. There is not only the issue of "ear power", but also the issue of personal preference. Therefore, various "matching principles" are popular in the fever world. I think it is called matching skills. It's not appropriate to call it a "principle". It's obviously a business hype by the agent. Over time, it has become a principle. A few years ago, some people called "Tianlang" and "Golden Throat" a "perfect match". A few years later, they also called "Zhuoli" and "Golden Throat" a perfect match. Since they were both called "perfect matches", why did it happen again? "New combination"? I think there is no unified principle. On the premise of practicing ear skills well, it is enough that you think it sounds good.

I often read some articles saying that improper combination of ×× equipment causes unpleasant sound, "Metal The "smell" is too strong or the "wood smell" is too strong; XX equipment can produce a velvet-like sound if it is properly matched. It's a joke. In addition to metal, the instruments of the symphony orchestra are made of wood (or synthetic). Who has heard the sound of velvet? Could it be? The curtain is singing?

If I have to talk about principles, my principle is "a good horse deserves a golden saddle, a blind donkey deserves a broken mill". A set of equipment is like a wooden barrel. How much water it can hold depends on the shortest piece of wood. In the entire system, the shortest piece of wood is the speaker. From a technical point of view, the speaker is the worst. Among Western musical instruments, pianos and basses The lower limit of the bass tube's low frequency can reach about 27Hz, and that of the pipe organ is even lower, but it's good if a home speaker can reach 40Hz, so some experienced audiophiles base their matching around speakers, which is scientific.

For example, the Rogers 3/5A, which has been hyped by merchants for many years, no matter how high-end the amplifier is, it cannot express the grand momentum of the symphony orchestra. As long as the listening environment and economic conditions permit, try to choose high-quality amplifiers. floor-standing box (but then again, no matter how high-end the floor-standing box is, it is also man-made, reflecting the designer’s own musical accomplishment, listening hobby and business orientation. It is impossible to achieve 100% Hi-Fi, but it is only closer. Hi-Fi only). Then choose the amplifier and CD player according to the requirements of cost-effectiveness and your own preferences.

7. Be scientific and rational, stay away from metaphysics and mythology

Some wealthy enthusiasts in Hong Kong and Taiwan still feel dissatisfied after purchasing hundreds of thousands or millions of equipment. , in order to find the exact landing point of each fragment of the broken bottle, to determine the exact age of Tsai Qin when she sang, to "punch to the flesh" and "ears to make oil", we began to construct a brand new subject - "Sound Theology" " or "Hi-Fi Metaphysics".

Various papers have emerged, such as "On the Impact of Qin Dynasty Bricks on Improving the Sound Channel Separation of CD Players", and "A Brief Discussion on the Effect of Speaker Cover Color on "Changes in the Impedance Curve", "The Effect of Rosewood Foot Nails on Increasing Power Amplifier Current", etc., some "fever tips", "techniques" and products have been introduced one after another, such as silk-packed shock-absorbing bricks, CD oil , CD magic film, CD magic pen; what kind of record freezing technique, amplifier tapping technique, wire irradiation technique; what kind of directional printed circuit board (you can’t even hear the left and right channels connected in reverse, but you can still hear the circuit board) directionality?), etc., some people do believe in these things that have nothing to do with science and art. I don’t know what the purpose of those who create audio myths is, and the unlucky ones are those who believe in audio myths , you have to spend thousands of dollars to buy shock-absorbing bricks, CD player oil and film, etc., but you may only know what these have to do with Hi-Fi.

I am neither Scientists are not artists, but they firmly believe that fever music should be a combination of science and art. It cannot be solved by practicing qigong or dancing. I hope that friends who are obsessed with it can get rid of their misunderstandings, turn around, and treat fever from the perspective of science and art. Bar.
