DC300 is a flagship decoder without considering cost, and there are significant differences in design and materials compared to some ES9038 decoders on the market. The transformer is a blue sealed transformer with excellent background details. The output operational amplifier uses MUSES03, which has four times better specifications than MUSES02, for output. The sound field, positioning, and air feel are all excellent. In addition, the display also uses a large OLED true color display screen, which is very luxurious!
Regardless of cost, we use JRC's highest order MUSES03 operational amplifier, which is superior to OPA627. The human voice is natural and delicate, with rich overtones and excellent sound field positioning. The disadvantage is that it is expensive!
