In the future, I would like to see a new USB-DAC with MQA3 (384,000Hz 32bit) (MPEG-H 3D AUDIO) (hybrid standard with MQA Studio & 360 Reality Audio) support, with a USB connector and SUB woofer pre-out jacks for DVD and Blue When the sound does not come out due to the copyright problem at the time of Ray DISK playback or U-NEXT viewing, the problem is solved, and CPU is an instruction, and if it corresponds to AVX2 or AVX512 and corresponds to the AVX function of higher performance, the function of higher performance of CPU is automatically selected on application, and it is thought that it is even better when it is possible to enjoy it with higher sound quality. The following is an example of a product that is not only a good product, but is also a good product. I would like to see such a full digital amplifier in the future, as of 2022/03/28.
