The recording of the D100 is very good. I have nothing to say. I listened to a live recording at a listening session in Chengdu. The effect was great, but there are also shortcomings. In fact, it cannot be considered a shortcoming. It is different from the D50. Accurate and indifferent, the D100 adds a lot of "artificial rendering" to it. Ignoring human noise, I can only say that what you hear with the D100 is the closest feeling "you" heard in that place at that moment. It's hard to say whether this feeling is still there when it comes to recorded CDs. It’s hard to say. The directivity is too strong, so you must use a monopod to hold it up to record, otherwise the sound will be blocked by the crowd. You must also read the manual for settings. In fact, the recording cannot produce the effect that human ears can hear. The sound is prone to popping at the scene, the level is difficult to set, and the sound is not as loud as the ordinary WAV sound. Fortunately, the details can be recorded, and the surrounding voices are louder than the lead singer.
