This product uses HIFI-level FPGA as the digital DIR and I2S asynchronous dual-receiving processing solution. It is a mature HIFI high-end solution. After a year of debugging, it finally has the opportunity to face everyone. The R-2R part adopts the mature R2R solution that our store has been selling for more than a year. Although it only supports the PCM format and does not support the DSD format, for now, it is indeed the most YI solution for users. This program is well recognized by HIFI Gaowan abroad. Therefore, we put more effort into designing this enhanced version, that is, adding FPGA processing part on the basis of the original mature solution.

At present, the performance has been brought into full play.
