In summary, the ASUS Xonar Essence One worthy of its official propaganda "HiFi decoder" in the title, regardless of the quality of analog output, or headphone amplifier output quality of the HiFi (sound of, or "hard" indicators) are picked on What's wrong with not too obvious, in line with the "real reduction" requirements: neutral and transparent sound, good analytical, sense of speed and without the dynamic compression, if you must, and similar relatively high price of the decoder, then the instrument overtone, vocal finish processing of 3D sound field sense, the sound of separation still exists a certain lack of, in no special tuning on the "art" and "personality" of the place. Considering its price (4000 yuan or less), so the sound quality and provides a very practical amp features, I believe that is still relatively good value; and taking into account the background of the brand ASUS, this tuning style, you can understand, after all, ASUS PC hardware is started, have to face is the most popular users, the most popular flavors.
