Recommendations on a digital system

I have a Pass X1 and Bryston 4B SST and I want to go digital. I need to figure out the connections I will need and if that Pass/Bryston can handle it or if I need to sell and buy something new. I don’t have a streamer yet, I don’t know what to get. I’m also looking to use my lifetime Sirius signal somehow as well. Please give me some ideas on a streamer/DAC/CD ripper that possibly has a headphone amp. I also have Sirius lifetime that I would like to incorporate. My hopes are to do all this without needing to use any switches or unplugging/plugging in connections when changing source. No wifi, modest prices (used gear on Audiogon or eBay?).

I just read a post where the poster had tried almost every DAC and streamer out there without really explaining the price point and quality in each. I'm too old and don't have enough time to try and sell/buy the next thing. I'm looking for honest recommendations and affordable price points or links to equipment on Audiogon if possible. I'm pretty sure with all the audio experience on this forum I can get a few recommendations!
