If I go this route
Don’t do it, life is to short to start all over from scratch. Instead focus on a GREAT streaming setup and room treatment. If you get your room acoustically pristine even youtube can sound better than it has any right to. I happen to prefer DSD and got a Sony front end from their signature line that can remaster tracks into DSD from any source. Many DAC’s can upsample into higher resolution PCM files. You will be very happy and basically have an infinite catalog from your streamer.
Your system looks great but what about how your room measures? Do you have the FR graph?
