There is no need for too much theoretical analysis and debate, but take a disc and compare it to the practice to make the truth.
Computer: Original CD lossless whole track + foobar player + interface + decoding + ear amplifier + HD650
CD side: D150 + ear amplifier + HD650
【Contrast feeling】
Comparison album: Ren Xianqi's "Heart Is Too Soft"
1- The overall sense of the CD machine is more rounded and flexible, an album can be from the beginning to the end of the song until the end of the playback and want to listen to another round; although the computer side of the clarity is no problem, do not know why listening is to feel restless, several times are subconsciously want to cut the song;
2- The contrast between the fireworks accompaniment at the beginning of the tenth fairy tale song is more obvious: the computer side listens to the sound of the small fireworks that sting and stab, and the CD player is a very three-dimensional high-altitude blooming fireworks, as if the immersive sense of the festival atmosphere is indeed impossible to achieve in my current playback system;
The fireworks heard on the computer side are similar to this picture
The CD player hears that it is a dynamic space that lifts off, blooms at high altitude, and annihilates
Many unconscious comparisons have also verified this contrast feeling, and the musical impressions brought by the physical CD seem to take a lot of effort to realize on the computer-side decoder.
