I think that from the latter half of 2022, a full digital amplifier or speakers equipped with a hybrid next-generation audio format, MQA Stduio Ver2 (384,000Hz 32bit) and MPEG-H 3D AUDIO (360 Reality Audio) via USB connection with a PC will be more popular than USB-DAC.

Since the sound quality seems to be better when a computer and a full digital amplifier are connected digitally via a USB connection without loss of DA converter, it is likely that a full digital amplifier will be used from now on with MQA Stduio Ver2 (384,000Hz 32bit) and MPEG-H 3D　AUDIO (360 Reality Audio) and hybrid next-generation audio formats will become popular. I think that the economically illiterate Prime Minister Kishida and China's Xi Jinping are making the economy very bad along with the new coronavirus with their policies that have a negative impact on those who invest, etc. I would like them to resign as soon as possible.
