Listening to classical sounds, the most important thing is the sound quality, generally speaking: vinyl >; Digital files of CD & gtDVD & gt sound card >: Walkman >；; MP3。
DVD is mainly video, but the music field is not strong. Japanese CD players, Sony, Panasonic, Yamaha and marantz in the United States are all first-class (I won't talk about brands in the top field, because there is no end to burning money, I only say that white-collar workers and well-off families use HIFI, but the rich don't).
Popularize common sense
Music equipment: sound source (CD/music file)+player+power amplifier (power amplifier/amplifier)+output equipment (headphones, speakers).
Sound sources are overwhelming, and inferior sound sources can never be restored to first-class sound. It is no use using any additional equipment for inferior sound sources. The sound source of vinyl disk is the best, non-digital sound source, no digital-to-analog conversion (DA), the original flavor is the most authentic, but it is expensive, easy to wear and tear, difficult to maintain and use, and has been eliminated. Secondly, CD is a digital audio source, which is obviously better than DVD. The sound of DVD is hard and cold, and the genuine CD is far better than the digital file. If you use digital files, lossless is definitely better than lossy. So the genuine CD is very important.
In addition to the sound source, the most important thing is the player (this is true for classical music, but if it is a home theater, the power amplifier/amplifier is more important). CD/DVD has less internal interference, shielding interference between components, stability, arbitrary size and special use, which is much better than PC sound card.
Players (sound card, CD complete machine) include: 1. Digital signal reading and decoding output (digital sound card, turntable part of CD player) 2. Digital signal conversion analog signal (DAC decoder/digital-to-analog converter). These two parts are very important, among which 1 is the bottleneck of PC HIFI, and it is not as good as CD player. 2 is the core of audio reproduction. Whether the repair is successful or not depends largely on DAC.
At present, CD player and ordinary sound card are integrated in two parts, but they can be disassembled. For example, buy a high-grade DAC, and then the digital sound card (only outputting digital signals, not DAC) and CD turntable share this DAC.
Power amplifier and amp are used for signal amplification, which is very important for the shocking effect of home theater, but not very important for classical music. Some DAC decoders and CD players have integrated signal amplification function, which is basically enough.
The output device earphone is suitable for one person to listen to, exquisite, easy to carry and not tired of listening; Speakers are even more shocking, especially movies. The status of speakers is definitely not as good as headphones, but it is easy to disturb people. In classical music, the sound quality of headphones is better than that of speakers, and the value ratio within 1,000 yuan is about 5: 2. That is to say, the sound quality of 200 yuan's headphones is the same as that of 500 speakers, but the speakers can be used by many people, and the headphones can only be used by one person at a time.
