Environmental factors include the time, space, and influence of people around you. If you buy a set of audio that will affect your life, it may be a size problem, it may be a price issue, or it may be a matter of appearance. As long as it affects your relationship with people around you, then this set of sound is definitely Not a good sound that can make a difference. At this time, you must change the mentality of your choice of equipment, choose a set of equipment that can make you happy rather than bother, if you can not change the environment where the sound is placed, then change the mentality of your choice of equipment.
What is “high cost performance� Are you confused by this business word?
When choosing audio equipment, the price/performance ratio is the decisive factor we often talk about. As the most popular keyword in the audio circle in recent years, it is used as the most powerful promotional word of the product. Compared with the high sound quality, more enthusiasts are pursuing Cost-effective products, what is the price/performance ratio? This vocabulary comes from the English "C/P Ratio", also known as "C/P value", C is Capability, performance, P is Price, price; using mathematics to interpret Capability divided by Price must be greater than one. The larger the value, the higher the cost. Simply put, harvesting more than paying is the true meaning of cost. In fact, performance must be a parameter that can be measured and quantified. It can be directly compared. For example, a car can travel up to 300 kilometers per hour and the other can only reach 200 kilometers. Or, a camera can support HD 4K movies. The other can only shoot 1080P. To be fair to performance, it must be quantified or digitally displayed. However, the acoustic elements are extremely difficult to quantify. Therefore, the so-called price/performance ratio in audio equipment reviews is often just a piece of audiophile. Empty talk.
Cost-effective equipment, may not be a good equipment!
When talking about the price/performance ratio, we must adhere to a big principle, that is, to compare products of the same price, compare the products of the same type, compare apples with apples, and compare watermelons with watermelons. In the audio circle, many commentators will compare the individual functions of the equipment to try to highlight the selling point of a certain product. In addition, they will try to compare the products of different price segments to highlight the low-priced products. price. Perhaps, as long as it is judged to be cost-effective, sales can be guaranteed. However, as the saying goes: "The Navy is a sailor", the high cost performance can only reflect that the equipment is better than other options in the price segment. It does not mean that the product itself has high quality, nor does it mean that it can meet the requirements of enthusiasts. In fact, senior enthusiasts will understand that audio equipment is not a penny of goods, blindly pursuing cost-effectiveness, perhaps just set limits for themselves, and never reach a higher benchmark.
A beautiful misunderstanding, there are not many cost-effective equipment, but too many products that are overpriced.
In the audio world, when manufacturers set the price of equipment, they often do not use performance as an indicator. “The price of sound is the most common way. No matter how low the production cost is, how the function is lacking, how the appearance is simple, as long as the final sound quality Outstanding, it can be matched with high pricing. However, as everyone's definition of high-quality sounds is different, a large number of fever products have begun to appear in the audio market. In my opinion, good equipment does not refer to the best products at this price, but products that can meet the requirements well.
In the absence of information and limited choices, we often choose to change our requirements or to good standards. Naturally, it is easy for us to choose the wrong one and decide to buy a product that we did not completely like. In a limited comparison, the good definition will be different. It is worthwhile to decide how to use this product. However, the good standard should be stable and not easy to change.
The sound technology contains two elements: "Selecting the vision of the equipment, and the method of playing the equipment."
What is a good voice? HiFi high fidelity? No, but the sound you like, absolute HiFi high fidelity has always been non-existent, otherwise the specifications of the equipment have been unified, there is no difference in tone, no different sound effects are allowed. I ask, when you choose equipment, you will ask yourself if you want to buy a high-fidelity sound. Every enthusiast has been pursuing a sound that makes your ears happy. It is your favorite voice, so the good voice in your heart, It doesn't mean the good voice of others. You only need to use 10% of the skills to make your favorite voice. On the other hand, a good sound system is not a matter of buying equipment, but you also need to work hard and get along with the equipment. If you have good equipment, you can hear good sounds. The sound in the sound show and the agent showroom should be the best. Fortunately, audio is not a reproducible thing, it contains a lot of technology and gameplay, so giving up learning is equivalent to staying away from good sounds.
In the Mainland, many enthusiasts will pursue some high-priced audio accessories to save the deficiencies in the system. If you adjust the sound in this way, I can share a tip with you. Good audio equipment must be easily distinguished. Even if it is A/B/A, it should be one. Listening can immediately hear good and bad, to listen carefully to hear the difference between the equipment accessories are optional, not worth the heavy money on these accessories. At the same time, don't choose accessories that you don't understand or are not easy to use, which is a waste for you. Good accessories have a common feature, not that you can get better slowly after you join, but you will get worse soon after you swap out.
