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!

About 3-4k. Used is my only option. I saw a Cocktail Audio X40 refurb for 1299. but I don't know anything about them and no headphone amp or Sirius input but there maybe none made with those options.
Innuos Zen Mk3 streamer/CD ripper/DAC is an excellent unit that can be had for $2600 new, which leaves you $ to get a decent headphone amp like a Burson Soloist. Darko has a review of the Zen Mk3 for more info.  Just one option. Best of luck.
I saw a tear down of the Innuos on YouTube and it isn’t worth the highly inflated cost.  Might have good reviews but the quality of the internal parts and the casework shows it is way overpriced. 
Oh, here we go again. The ol’ haphazard accusation of an overpriced audio component based on component parts thing. Ok, I’ll bite. (BTW, are you buddies with kenjit by any chance?).

@sfseay — overpriced compared to what? You’d say the same thing if you tore apart a Lumin or likely anything else. Yes, there is a markup required for these companies to cover their development, materials, labor, overhead, etc. costs and make some profit doing it so they can stay in business. Welcome to the real world. The market decides what’s overpriced, not you. And if you’re right, which I highly doubt, Innuos will go out of business due to competition that sounds better for less. Of course, you’re perfectly free to go buy the parts yourself and try to build something that sounds as good as the Zen Mk3. Good luck with that.
