This machine adopts the original CD movement DA11 with very good disc reading ability, which is stable, fast and accurate. The transformer uses higher quality copper wire and iron core to make the low frequency more plump and elastic. And add a shielding cover potting resin to ensure that small signals are not affected by electromagnetic interference, reduce the vibration of the transformer, and make the movement more stable when reading discs. The capacitors are replaced by NICHICON (Nikon) BP and FG high-quality audio capacitors. The high and low ends of the sound extend better, and the entire frequency band is more balanced. The op amp is changed to 4 single op amp OPA604, which makes the separation of all levels better and prevents mutual contamination between the levels. It makes the details of the machine more abundant.

On the basis of the upgraded version, a professional USB decoder board is installed.

Using the professional USB decoder chip PCM2706 from BB Company in the United States. Using PCM signal access, it is more stable than coaxial signal, and the sound quality is better. Adopt independent self-power supply mode, non-USB power supply, make the power consumption of the chip more stable and sufficient, and avoid the interference caused by USB power supply, so that the performance of the chip can be better displayed
