1. How do you evaluate Sony MDR 1A DAC?

After joining Silver 1ADAC, I found that it is similar to what the poisonous articles on the Internet said. It is very suitable for pop music. The sound separation and presentation are very faithful. In addition to being suitable for more "noisy" pop music (with many instruments), it is also suitable for movies and animations. It's all good to wait. Another point is that when the DAC is turned on, the human voice is a bit "distant", that is, the analysis of the soundtrack overwhelms the human voice, so that the details of the human voice are slightly lost, and the taste is not enough. For example, when the singer expresses emotions, he is slightly Changes in breathing sounds. I jumped on the upgrade line without hesitation, the vocals were significantly improved, and the taste was finally right. I haven't tried the msr7, so I don't know the final gap between them in terms of vocals, but I feel quite satisfied with the level of the upgraded line. Finally comfortable. But here comes the problem. Now I connect the upgrade cable to iPhone 5s without turning on the DAC... And I compared it with 1A in the store. I also connected the upgrade cable. The effect of 1ADAC is better than that of 1A. It may be because the former clamps the ears more firmly. It may be that 1A is not turned on (the silver one on the second floor of the Sony Huaihai store is rarely used by anyone to try it out. I won’t mention the black one on the first floor that is turned on), but my 1ADAC has only been listened to. Until 20 hours.
