Is the grade of headphones obvious?

The grade of headphones is divided into several basic levels.

1-2000 yuan is basically a reasonable grade.

2000- 10000 yuan is basically the limit grade of the production version.

It's basically a limited edition up there.

First of all, earplugs can't compete with big headphones. 3,003,2000 yuan to increase the front-end driver of headphones can also play, saying that the ultimate sound quality is still a big earphone.

Why is the direct push earphone direct push? Because its resolution is not high, that is to say, all the details that the earphone can show are basically the details directly analyzed by the computer or mobile phone, and the two intersect.

The resolving power of HIFI headphones above grade 2000 has greatly exceeded the upper limit of computer direct analysis, and the thrust can't keep up with ordinary headphones. At this time, the front end is needed. At this time, some people will ask, how can a computer with such strong computing power not be analyzed? The focus here is not analytical power, but interference, and the focus of interference is electricity. Although the digital signal is transmitted now, in fact, 0 10 1 will not be played at the same speed as in the ideal situation, and there will be a deviation before and after because of any possible interference, just like a car driving on the road. This has greatly led to the distortion of music playing. However, these distortions are undoubtedly manifested for headphones with a resolution capacity of more than 2,000 yuan, which is naturally a great harm to clarity seekers.

Among many disturbances, the worst is electricity. Because electricity is the source of energy, there are high and low pulses, just like a person should have a constant working state, but sometimes he works fast when he is full and slowly when he is not full. Can the effect of his works follow an ideal constant speed? No way.

So, a stable food supply, ah no, current is one of the keys to eliminate interference.

Nuclear hydropower is a joke, but the improvement of a power station, a wall inserted in advanced equipment (so advanced that you can't hear it on a 5 thousand thing), basically comes out with one ear, and the clarity is not the same level. But a linear power supply can be recognized by DAC at the level of 1 ten thousand yuan, so I think the line power supply is very cost-effective.

The following are some common misunderstandings. In fact, why should we emphasize the separation of decoder and headphone amplifier, and the separation of audio source (especially computer)? This is mainly electricity, because the decoder requires converting the finest digital signal into high-fidelity analog signal, and the most important thing in this is the independent clock, that is, I set up a stable queue myself, and the chaotic car queue will wait for me at the traffic lights first. Then, under my command, I drove out one by one at a very precise speed and ran out of a stable team at a constant speed. In this way, there is a high-fidelity digital signal 0 10 1, in theory, except for an extremely high-fidelity analog signal. All this is delicate work, but if you put your clock with the network card, graphics card and CPU in the computer, how can you keep its accuracy? Because you use electricity in the * * *, just like a child who wants to practice balance beam and several trampoline children are on the same trampoline, you can't keep him level.

Headphone systems generally have sound sources (computers, CD players, turntables, etc.). ) to ensure the output of digital signals. Then access DAC through asynchronous system, that is, set a waiting place, stop for me first, I'll call a car and you drive there (USB asynchronous interface). Then there is the DAC. The level of DAC mainly depends on the clock. The basic value of a good clock is 1W (whether it directly exceeds the earphone, in fact). The clock is an absolutely accurate team guarantor, which ensures that all cars line up for me smoothly, and then the digital signal is converted into an analog signal through digital-to-analog conversion (DAC). Next, I want to zoom in. At this time, I have a negative with very high pixels, but you can't give me virtual focus and distortion when you enlarge it. At this time, the power of the power amplifier needs to be stable, but at this time, because it is only amplification, it is a rough job, so the power requirement is much lower, but it cannot be too bad. Finally, put the enlarged photo into the earphone, which is actually just a photo frame and the cheapest thing in the whole system.

A Senhai HD6000 with more than 2,000 yuan, you speak directly into his mobile phone, which is a headset with 500 yuan. You give him a basic front end of 5000 yuan, and he produces a voice of 7000 yuan. You give him a front end of 15000 yuan, and he produces a sound of 17000 yuan, because under his accurate analysis, the ambiguity caused by your front end interference will be put in.

In fact, the advanced HIFI headset system reflects good high fidelity distortion. So reduction is the foundation, and tuning is the key. After the analysis, every device, even every line, will intentionally or unintentionally add its own sound color because of inevitable interference. It is these sounds that are likely to become its signature. For example, the famous warm tone dyeing of gallbladder machine is caused by strengthening the even harmonics that will produce warmth during the signal amplification process. Many people use this distortion to change the direction of sound by changing different wires.

Finally, I want to say, in fact, the limit difference of headphones is still very big, especially after you listen to a high-quality recording carefully and remember all the details, you will find that the headphones in 5 yuan are huddled up, and those in 500 yuan are slightly divided, which is a little low-frequency or analytical. The old flagship of 2000 yuan, HD600, K70 1 880, are all below the front end of 5000 yuan. The accompaniment reminds me that the low frequency hits the stomach directly, and the high frequency rises against the forehead (three-frequency extension). When you are gentle, you whisper, and when the momentum comes out, it suddenly shakes your whole brain (dynamic). At 3 o'clock, there is a violin on the left, a piano on the right and a saxophone in front, which is very clear (like a knot). Then the human voice sounded, from inhaling, to swallowing (analysis) of breathing, to the slightly hoarse texture of the voice, and each timbre was full of thickness and volume (dyeing). You will begin to yearn for such a song more and more.

At this time, the legendary fever began.

At this time, you will feel that the high frequency is not good. A little control and a different power amplifier (such as 70 1 can greatly improve the high-frequency burr) will improve, so happy. The low frequency is a little slow, and the DAC switches to linear power supply. Wow, so powerful. I'm so happy. You adjusted a set of equipment until you listened to the song you heard 100 times, and every detail was printed in your mind. Wow, all rashness has been corrected as much as possible. You are satisfied.

Until one day, you went to audition, picked up 009, Da 'ao, R 10, these ancient artifacts, and released that familiar song at the front end over 2W. At this time, you find that the environment you are familiar with, the performance room, is actually separated by a layer of gauze. At that time, you knew that the gauze began to recede and every tiny cigarette was there. Then you will know that you don't really have much money. You know, your tiny device really doesn't have much analysis and something to be proud of in front of them. Then you go home with sadness and a little luck, listen to all the songs you are familiar with with with your carefully adjusted equipment, and say to yourself while listening that it is still the songs I am familiar with. You see, it's just more charming, analysis is nothing, and quality is not important. Finally, you fell asleep with a self-deceiving smile.

Then when you have a chance to get in touch with KK, you know it will be a deep blow, but you took the CD, and you rushed into the meeting like a fool. . .

My front-end auneX 1s is used as an interface to connect LAVERY DA 10, and my ears are amplified with OBE cyber20, Blackvoice 337 and Lyman. Headphones are mainly K70 1, HD600 and iron triangle AD 1000X, among which AD 100.
