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!

Definitely want to implement my Sirius lifetime subscription. I assume that none of the streamers available don't have Sirius radio capability so I will have to use the output from a Sirius radio cradle to the input of a streaming unit? Thanks for all the posts, this is to me the hardest part of putting my system together. So far I have the Pass X1 preamp, Bryston 4b SST amp, and a Marantz cd player. For the life of me I just don't now how you would tie these together with a streamer, DAC, headphone amp without having to unplug/plugin different components. I'm trying to avoid that.

You can stream XM - Sonos and Roku will both do this and I'm pretty sure there are others. You'll get much better fidelity from the stream that you will from the satellites, although you do need to set the app for highest quality.
So the signal from Sirius radio is not a quality signal? I guess I could use it leisurely but I have no doubt the source is as important to me in my system. I do know this, just like a computer, a good speaker is "garbage in, garbage out"!
I get Sirius for "free" with my satellite TV subscription and had it in my car when I bought it.  It sounds pretty bad compared to most streaming sources and FM radio.  I'm not sure if a streamer would provide better sound quality, but the Marantz streamers will work with Sirius as will Sonos and some others.  I think there's a reason most of the higher end streamers don't include it as an option.
@OP,
As you have the Sirius subscription, I would just get a Bluesound Node.
With that you can use your subscription, but still be open to number of higher rate streaming offerings.
Plus, you can output to a better DAC than the one in the Node should you want to pursue audio perfection.😉
The nice thing is that you can buy a used Node for not much money. The only difference between the old and new Nodes is wireless connectivity, so if you don't need that, you won't be losing anything, as the Bluesound app is upgradable. (I know, I own the original Node cubes. They still work as they should).
