[Home Theater Network HDAV.com.cn] In general, Hi-Fi and Hi-end have excellent indicators on conventional objective technical parameters. However, if Hi-Fi and Hi-end are distinguished by these conventional technical parameters, it is inevitable that they will be biased. The conventional technical parameters are the basic means and methods for measuring the pros and cons of audio equipment. An excellent technical parameter is essential for both Hi-Fi and Hi-end. However, people's hearing is limited in sensitivity to technical parameters. For example, the difference in distortion of a few thousandths or the difference in the imbalance of a few decibels is difficult for most people to detect. However, whether it is the design and manufacture of audio equipment or the enthusiasts of the welding machine, there is such experience in their own practice, that is, some technical parameters or technical characteristics other than the conventional technical parameters have certain sound and sound quality of the equipment. Impact. For example, the introduction of negative feedback and the choice of negative feedback depth will have a greater impact on the timbre and sound quality, but it has little to do with conventional technical parameters. It is also said that the audio equipment deals with a signal with a large frequency component and a large amplitude of the signal in a wide frequency band. This signal is difficult to express in a simple mathematical mode when passing through a nonlinear system.
As far as the technical parameters of audio equipment are concerned, the usual Hi-Fi equipment is basically the conventional technical parameters pursued and guaranteed, and often strives to achieve the highest possible index. In addition to the conventional technical parameters, Hi-end equipment often pays attention to deeper technical parameters and technical characteristics. Therefore, Hi-end equipment may not have obvious advantages in conventional technical parameters, but its subjective sense of hearing has left a deep impression. There are many factors that affect the quality of equipment. In addition to the perfect circuit design, the selection of manufacturing processes and materials is also critical. This can be said to be one of the differences between Hi-Fi and Hi-end. In general, Hi-Fi equipment is in high demand, and the design of the manufacturing process in the production process is often as simple as possible to reduce costs. The selection of components is also as high as possible. Hi-end's equipment is different, because Hi-end's market is much smaller than Hi-Fi, and if the quality of the equipment is not enough, users will not think it is Hi-end equipment.
Therefore, Hi-end equipment attaches great importance to the manufacturing process, and often pays attention to the position of a wire and a solder joint. The originals used are made of some brand-name quality products. For the appearance of the equipment, it is even more important, and often strives for the coordination and exquisite appearance, so that the mechanical center of gravity and mechanical vibration characteristics of the equipment are not neglected. In some audio publications, words that describe Hi-end equipment are often seen. For example, when using components, use "exhaustion", when using the appearance, use "image power", when talking about crafts, use "exquisite" Absolutely." These words are indeed the objective characteristics of some current Hi-end equipment, but for the user, his pursuit tends to pay more attention to the musical expression of Hi-end equipment, which means that when chasing Hi-end equipment, more attention is paid to Its sound is "quality."
The Hi-end equipments, which are "extraordinary", "exquisite" and "exhausted", are expensive and far away from most music lovers. However, the products are determined by the needs of the market. There are also a class of equipment in audio equipment. These equipments do not pursue the image of “powerful†and the “exquisite†craftsmanship, and use limited cost budgets to improve the “quality†of sound. on. So that the equipment with Hi-end equipment quality is closer to more music lovers. For such high-quality equipment, we might as well call it "quasi" Hi-end equipment. It is difficult to say that there is an obvious technical parameter boundary between Hi-Fi equipment and Hi-end equipment, and it is not easy to distinguish Hi-Fi and Hi-end by appearance and market price. Can a device be called Hi- End, often needs to be evaluated by its subjective listening experience, its own technical parameters, manufacturing process and price.
