I remember a few years ago to see a Hi-Fi article about fans of "red eye", "stare", "White Eyes" and "3" on. "Red Eye" is the fans to see the favorite place equipment in the store after doing everything possible to coax his wife to spend money to buy down; "stare" is that once the equipment purchase will increase, the likelihood is imagined not pleasing to the eye, listened along does not sit well, but money has been spent, can not really stare. "White Eyes" is the wife asked, "This buy-back right?." Can only bite the bullet and say it back to buy the very satisfied with the looks of contempt from His wife. More experience do not know have the same sense? How to be a smart consumer Hi-Fi? In fact, we just clear the purpose is not difficult to buy a stereo. If you want "some people have I," then buy a cheap so; If you want to "show off", then choose a most expensive so; if to decorate the room, then you buy a Well, that looks extraordinary. If only a small room in your hou se, you buy a most compact component systems better. Suitable for use as long as that smart consumers. How to Buy Audio? I conclude, there are about a few tips: Need to know before buying equipment, common sense ---- Hi-Fi equipment, including a special CD, a Amplifier (Senior product decomposition level for the former and the latter), a pair of Speaker . Good sound prices are high, but less demanding, two or three thousand dollars, they can do sound, the division is a relative price, but the sound has always had "a penny, a sub-goods" argument. Advanced Audio Designs created an attractive appearance, middle and low sound due to cost constraints, are often difficult to best of both worlds, many of the poor quality of the sound to make the appearance of a large, very impressive, but its function may not be a good sound quality . Sound quality is important to look important? I think we all know. There are many on the market called for the United States, Germany, United Kingdom Home Theater Most of our products in Guangdong and Fujian coastal areas of production, and many are still inferior products. Fraud in this area so special and more. Sound common technical indicators: (1) distortion, the lower the better CD, Amplifiers The distortion rate is generally lower than 0.1%, while the speakers rarely show distortion, a good speaker most about 1%. (2) frequency response, the more widely as possible. CD, amplifier frequency are wide enough, you can not consider, and speaker frequency response should reach 50 ~ 16000HZ, both ends of the extension of the more widely as possible. (3) amplifier power, generally tens of watts, a large several hundred watts. Consider the family to listen to space is not too much should not be blind pursuit of power. The same price, sound quality should be pursued, rather Mody low power, high-quality amplifier, do not high-power, low-quality machine. (4) sensitivity, speaker of the lower sensitivity of the sub-high school f riends, most of the sensitivity of high-level speakers are not high, so high-level speakers are often difficult to push (hard to push is difficult to meet the speaker power amplifier power demand, it is difficult to achieve the most good sound effects) was to look at the speaker as a low 85dB sensitivity, to 88dB or more as high sensitivity, in general, threaten not to buy less than 85dB sensitivity speaker, otherwise it will need a great power amplifier to drive.
