We have been asked countless times: the question of sound comparison between digital players and N-million CD players. In fact, although digital players and CD players are both digital audio sources, they are not the same product. For example, if you compare a well-adjusted LP record player with a more expensive CD player, the CD player will definitely not be cheaper. In the same situation, due to the different music carriers played, if a digital player plays some high-quality high-definition files, it will definitely exceed the performance of a much more expensive CD player. There used to be many people who took the CD-ripped files and compared them with the CD player. We think this is unscientific. The rip files are not as good as the original CD records anyway. In this case, when compared, the player will even lose to a CD player that is even cheaper than it. In addition, high-definition files also have good and bad qualities. Record companies are worried that high-definition files will be copied repeatedly, so it is difficult to buy the best recordings on consumer websites. Even high-definition files will fail if the quality does not meet the requirements. Give CD. For example, Muterla's famous version of "Song of the Wanderer" sold on HDtrack.com will definitely lose completely if compared with the CD. For digital players, its direct comparison object is PCHIFI systems of similar price range. Due to the interference caused by the switching power supply and the shortcomings of the USB interface in data conversion and transmission, it is difficult for PCHIFI devices of the same price to reach the level of digital players in terms of sound. If you must directly compare it with the CD player, you can use the digital output port of the CD player itself to connect to the digital input port of the digital player, and compare the sounds of the CD player itself and the digital player connected to decode the two states. Of course, such a comparison is difficult to be completely fair. The CD player is transmitted internally through I2S, and there will be some loss through digital output transmission. Therefore, the effect of the player will be slightly discounted, but it can basically reflect the The decoding quality of the two machines. Therefore, the comparison between CD players and digital players is actually a comparison of the decoding part. If a digital player can achieve better results than a CD player under such circumstances, then the decoding part of the digital player will be much higher than that of the CD player. To sum up, we believe that every piece of equipment should play its due role. Nowadays, we can get many high-quality SACD image files and high-level transcription files such as vinyl and open tapes. The real advantage of digital players is that CD players cannot match it.
