Roon needs a server (they call it "Core") to run the program, and a streamer (what they call "end point") to stream to your DAC. They can often be one and the same (i.e. a laptop you connect directly to DAC via USB).
A quick look at the Roon Ready list, shows several compatible Bryston BDP streamers:
You will still use your current laptop to run the Roon server (the "Core"). Based on what you already have, you can certainly give it a try. They do free trials, I believe 30-day. Then you can see for yourself if you like it or not.
P.S. I forgot to mention the third component of a typical Roon setup - the remote. This is what you use to control and play via Roon, and can be your smart phone (app), or a tablet. Of course, you can also use the laptop you use as a Core as a remote too. The same laptop. But, controlling everything via a phone or iPad makes it much easier and elegant.
