Audio, music and life: 30 points of my experience playing audio

01. There is no bottomless pit of sound. The sound that you feel good about is the best sound in the world. The music is endless. The music that you feel you like is the best music in the world. The sound has no peak. The acoustics in the middle seats of the first ten rows at the venue are the best.

02. For audiophiles, records are like drugs, and audio fever is like burning silver paper. But the records that I like to listen to repeatedly are often no more than ten or eight. Therefore, when buying "poison", seek refinement rather than quantity. If you want to buy, buy the best "poison". In this way, you will not be disturbed by common poisons and "salivare at the sight of poisons". According to recording technology, the types of CD records currently on the market are arranged from low-level to high-level, including: cd, dsd, lpcd, Hdcd, xrcd, xrcd2, xrcd24, sacd, dts, vinyl cd, etc. According to the quality of the substrate, there are: silver disc and 24K gold disc.

03. It is not a bad thing to have non-fatal shortcomings in the sound. It is a kind of beauty, and the beauty of imperfections is beautiful. It can make people continue to pursue, even dream about. It's dangerous to get it right in one step. It's easy to have a fever, but it's hard to get rid of it. If you reach the so-called perfection when playing audio, haha, then you will end up at the end of the road - jump off the building.

04. Hobbies vary from person to person. Speakers also have personalities, and people with certain personalities like different speakers. There is no comparability in comparing speakers with different personalities to people with different personalities. A wife is the beauty of others, and the sound is one's own beauty. This is the truth.

05. Music is a part of life, and it is an important part. Owning a speaker is equivalent to owning music, owning music is equivalent to having happiness, and owning happiness is equivalent to having a happy life.

06. People who love music may not necessarily be happy, but happy people must love music. A woman who loves audio is a good woman; a woman who loves audio is a good man.

07. People must have one or more healthy hobbies. Hobby is a kind of sustenance, a pastime, and a kind of physical and mental cultivation. Hobbies can be addictive. If you are addicted to smoking and drinking, or you are addicted to pornography, gambling and drugs, it is better to be obsessed with audio. Audio fever is the best choice.

08. What are the factors that affect sound? It ranges from players, power amplifiers, speakers (three major items), power cords, audio source cables, speaker cables, bridge cables (four lines), etc.; to medium-sized ones, it ranges from records, environment, placement, sound-absorbing facilities, equipment racks, mood, etc. ; Everything as small as the foot nails and pads, the levelness of the player, the shock resistance of the power amplifier, the cleanliness of the magnetic heads, the welding materials of the wires, the tightness of the connections, etc., all have a large or small impact on the sound quality of the equipment.

09. Strictly speaking, good records are the source of good sound. Players, power amplifiers, speakers, cables, etc., only play the functions of faithful interpretation, processing, and broadcasting, but cannot produce beautiful sound. The quality of equipment can only be measured by the degree of Hi-Fi it reflects the music information in the record. The highest level of Hi-Fi is the sense of presence. Under the premise of good records, the better the equipment, the higher the Hi-Fi level, and the smaller the difference from the live performance. Generally speaking, every time the music information in the record is processed by an electronic component, every wire is transported, and every welding joint is connected, there will be slight distortion. What's more, from the record to the sound being played, it has to go through thousands of processes. It is impossible to avoid distortion at all with only electronic components, as well as circuits, welding ports, etc.

10. A good record should meet the following conditions: first, the performer (singer) performs (sings) well; second, the recorder records well; third, the base film is good; fourth, the track is liked by people (Varies from person to person).

11. Some words often used to evaluate the quality of audio equipment are: fidelity, clarity, brightness, loudness, strength, sweetness, depth, softness, hardness, thickness, sparseness Density, sensitivity; sense of warmth and coldness, sense of roundness, sense of width, sense of tightness, sense of freshness, sense of transparency, sense of air, sense of space, sense of presence, sense of three-dimensionality, sense of speed, pine scent of violin (string), lines sense; sound image positioning, imaging; transient, dynamic, etc.

Comprehensive sound effects do not exist. If you want to be clear and delicate, it will be difficult to be broad-minded and honest; if you want to be light, strong and dynamic, it will be difficult to have a soft, sweet and mellow voice. Do we have to pursue everything? Then you need to prepare several sets of speakers or equipment! For example: two or three audio sources (CD players, tape players), two or three power amplifiers (tube amplifiers, stone amplifiers), two or three pairs of speakers (bookshelf boxes, floor-standing boxes), audio source cables, and speaker cables (copper, silver, gold , ribbons) three to five pieces (pairs), etc., with different styles, you can do as you like. High fever, that's all.

12. What kind of speakers (speakers) determine the sound quality of the sound system. Speakers are the key to determining the sound quality of a sound system or the success of the combination. Good speakers have their own personality. The choice of speakers depends on each person's personal preferences and cannot be generalized. It is often impossible to pursue a perfect speaker that has both your cake and eat it too. Similarly, it is also impossible to pursue a perfect sound source machine, a perfect amplifier, a perfect cable, etc.

13. The speaker is the key component that converts "electricity" into "sound".

Although the speaker is just a component made up of several speakers and several wooden boards, although science and technology have advanced by leaps and bounds since the invention of electronic audio engineering, speaker technology has developed the slowest. Why? The knowledge is so great that there are different opinions. There are endless words and endless books. Just like the dispute between Chinese medicine and Western medicine in the medical field, or the treatment of some difficult and complicated diseases: the diseases that can be clearly explained cannot be cured, but the diseases that can be cured cannot be explained clearly.

14. The so-called "three voices" popular in the audio industry nowadays are: American voice, British voice, and European voice (German voice). American speakers focus on strong intensity and huge dynamics, and have very large margins in various indicators. They are especially suitable for rock, jazz and heavy metal percussion, professional OK halls and other occasions. However, the musical taste is slightly lighter in terms of violin solo and classical string music; British speakers have typical European royal origins, with soft and sweet tone, dignified and elegant shape, flashy but not flashy, and a gentle and elegant aristocratic gentleman demeanor in the natural wood veneer. The British voice is warm, sweet, delicate, steady, and elegant. It has a very high status in the field of home Hi-Fi and even Hi-END, and is most suitable for classical string music and vocal reproduction. Unfortunately, it is less effective in expressing large dynamic scenes and low-frequency volume; German speakers fully embody the meticulous, rigorous and self-disciplined professionalism of the German nation. The German sound is natural, neutral and peaceful, clean and refreshing. It is especially famous in the industry for its exquisite workmanship, which is breathtaking. But strictly speaking, the sound of the German box is slightly colder and tougher, which is more suitable for the playback of pop music and symphony. Speakers from other countries, such as those from France, Denmark, Italy, Sweden, and Norway, embody the wit and romance of the French, the artistic atmosphere of the Italian Renaissance, the liveliness and cheerfulness of the Nordic people, and the extremely exquisite traditional craftsmanship. They are also very representative of the European voice: although The mid and high frequencies are slightly exaggerated, but the sound is pure and natural, with a strong musical flavor. And it has good compatibility, making it the best choice for home Hi-Fi/AV ??use.

15. In the audio market, there are hundreds of speaker brands, including internationally renowned brands. They are everywhere, but the quality is uneven and the prices vary widely. Even for speakers of the same brand and series, if the sound quality is slightly higher, the price will increase exponentially.

16. "Listening to music" and "listening to speakers" are two different concepts. Listening to music generally refers to music appreciation, appreciating the melody in the repertoire, the theme ideas expressed by the creator, the artistic level of the performer's performance, expression techniques, etc.; listening to audio refers to appreciating the ability and level of music performance of audio equipment, such as : Fidelity, clarity; sense of presence, three-dimensionality; sound and image localization; transient, dynamic, and music details, harmonic residual sound, etc. For most audiophiles, they listen to audio more than music. The focus is on listening to the repertoire that can best test the performance ability and level of the audio equipment, or the repertoire that can find room for the equipment (usually instrumental music: sketches, symphonies, etc.). In order to continuously improve audio equipment; for ordinary listeners, they only know how to listen to music and not to listen to speakers. As long as the songs are good (it does not matter whether they are genuine copies of records), the focus is on listening to the songs they like (usually vocal music: folk songs, pop songs, etc.) to get pleasure from your favorite tracks. Therefore, asking the general audience to listen to the sound is tantamount to "playing the piano to an ox".

17. Whether the sound combination is successful cannot be measured by the amount of money spent. The key lies in whether the equipment matches and whether the sound effect can be produced. Speakers are mainly for listening, not watching. The sound produced by the sound effect is a good combination and a good sound.

18. To maintain good performance of audio equipment, you must know how to maintain it. Maintenance methods include: first, regular power on and maintenance, which will help the machine generate heat and remove moisture; second, the volume should be turned up appropriately from time to time, which is good for maintaining good acoustic performance of mid- and low-frequency speakers. But be careful not to cause damage to the metal film tweeter; thirdly, often play piano music with a comprehensive range of high, medium and low frequencies. In addition to comprehensive maintenance of the speaker, it also requires the "baking" of the speaker box (wooden box). (Better overall effect) is also very beneficial; the fourth is to use the special disc for the burner, which also has a good maintenance function; the fifth is to pay attention to dust, moisture, sun protection, etc.; the sixth is to maintain the record, pay attention to dust , moisture-proof, insect-proof, anti-fouling, anti-scratch, anti-deformation, sun protection, etc.

19. For good sound effects, details cannot be ignored: 1). The bald head should be cleaned frequently; 2). Wire terminals should avoid soldering (line interfaces that must be soldered must be soldered with imported high-quality tin); 3. ). Power cords, signal lines, etc. should not touch the ground or make circles; 4). The CD player should be placed flat, the power amplifier should be shock-proof, the speaker should be placed steadily, the foot nails should be flat, and the speaker placement should be correct; 5). There should be a ground wire ; 6). Good shielding; 7). No interference from indoor magnetic waves and noise; 8). Regular degaussing; 9). Appropriate sound absorption measures, etc.

20. Listening to high-quality speakers (audio) is like tasting Huadiao Nuerhong that has been buried underground for twenty years. It makes people feel sweet, refreshing and long-lasting. The "sweet" and "warm" musical charm will make you forget time, space, and even your own existence and become immersed in the ocean of music. No matter how long you listen, you will never get bored, no matter how many times you listen to it. You won't get tired of it. Even if the volume is turned up to full power and the speakers are blasted to seven colors, you will only feel that various music sounds are so lifelike and natural that they even display terrifying shocking power, but they will never make you cover your ears and escape. ring.

21. For a large symphony concert, speakers with good sound and image positioning will make you feel the orchestra display as follows: left side of the stage: violins and violin group, rear left: piano and harp; In the center of the stage are: viola array, flute, oboe, horn, bassoon, trombone, trumpet, percussion, and timpani. On the right side of the stage is the cello array, and on the back right is the double bass array.

22. Laymen listen to volume, experts listen to quality. For laymen, if the volume is loud enough, the mid and high frequencies are loud enough, and the low frequencies are powerful enough, then such a speaker is a good speaker. For experts, this will only make people feel "very noisy" and annoying. Experts believe that a speaker with moderate volume, sweet and round mid-frequency, clear and pleasant high frequency, steady and thick low frequency, and music hitting your face like fairy music is a good speaker. But for the uninitiated, this just makes people sleepy and not enjoyable. This is all understandable. After all, tastes vary and cannot be agreed upon, just like some people like sweet potatoes and others like ginseng. People who like sweet potatoes want to fill their stomachs, and people who like ginseng want to taste them. Turnips and greens, everyone has their own preferences.

23. Developing good listening habits is the guarantee for maintaining good hearing. The low volume may sound difficult, but it is good for practicing keen hearing. So thin that even a tremor in the air cannot escape your ears, that is the "golden ear".

24. Evaluating the quality of a set of audio equipment is measured by the quality of the music replay effect. The sound effect cannot be seen, touched, or smelled. It can only rely on the ears. to determine. But ear judgment is an abstract judgment, and the results of the judgment vary from ear to ear.

25. Disease enters through the mouth, and disaster comes out of the mouth. To be in good health, you must: quit smoking, drink less alcohol and drink more tea, be indifferent to fame and wealth, and be free and unrestrained; eat scientifically and get enough sleep, and be optimistic and cheerful. To stay away from disasters, we must avoid talking about four things: don’t talk about family and country affairs, don’t talk about work unit matters, don’t talk about family matters, and don’t talk about people’s affairs. Talk more about: things about music, chess, calligraphy and painting, things about playing, playing and singing, things about cultural relics and antiques, things about flowers, birds, insects and fish, things about traveling in the mountains and rivers, things about heaven and earth, things about entertainment and sports, things about photography and videography, audio fever Things to talk about, pension and health care, even romantic affairs, etc. There are countless things to talk about. People are not nervous when giving birth to a baby, so why are you nervous about carrying a footbath? There are a lot of things to talk about, but we have to talk about the privacy of having a boy or a girl?

26. The effectiveness of listening to music is that the listener can achieve spiritual communication with the musician through listening to music, achieve the spiritual resonance with the musician, experience the ups and downs of life, and understand the joy, anger, sorrow and joy of life. Give people the enjoyment of spiritual joy and open-mindedness.

27. Tumors on the body can be surgically removed; inflammation on the body can be eliminated by taking Western medicine; yin and yang imbalance can be adjusted with traditional Chinese medicine. However, if you are upset, restless, restless, and disoriented, what can you do to treat it? I can't see it, I can't touch it, surgery won't work, Western medicine is useless, and Chinese medicine is ineffective. Perhaps the best panacea is music therapy. Music is the best way to cultivate your character, cultivate your sentiments, calm your mind, strengthen your mind and body, and prolong your life.

28. Appreciating paintings, playing with pots, tasting tea, listening to music... are the elegant enjoyment of a healthy life of body and mind! Eyes, ears, nose, tongue and body all enjoy unparalleled family happiness. They are indispensable, and they often lead you slightly into the cracks, and unknowingly reach the state of selflessness.

29. I once jokingly called my beloved purple clay teapot my "second wife." This is not only because a thousand pieces of gold are easy to come by, but a pot is hard to find. More importantly, if you take good care of your "second wife" and make her face shiny and round, it means that you have taken good care of your own body and mind. If you don’t believe it, you might as well give it a try.

30. A successful mentality is the greatest success, and a happy spirit is the greatest pleasure. In essence, listening to music is one of the pleasures that makes the spirit happy through the hearing of the ears. Washing your hair and feet, massaging in a sauna, watching football and flowers, traveling in mountains and rivers, fishing with a pole, etc., are all ways to achieve spiritual pleasure through the feelings of different parts of the body. Different hobbies vary from person to person.
