I have used almost all models of powerplants. There are now more and more people playing their music with computer or NAS. It is usually named as CAS system.
It uses computer, network router and/or network attached storage to stream data to DAC. High quality DC supply is needed, they are mostly 12V DC.
It will be very preferable if the future P20, or so, has high quality DC output. Technically there is certainly not a problem, it is the marketing that matter.
