I don't know what you mean by the "bridge option seems to have passed "?
To try Roon I'd suggest a Pi with a HAT which gives SPDIF output.
I have hifiberry ones on my various Pi and they are not shabby at all. Sometimes toslink gives surprisingly good results as all RFI is eliminated. Does limit you to 96 but for as many who upsample there are a multiple who don't. Roon's main selling point is its GUI and metadata
Google allo digi one for another option.
Digital front end is one area that for not much outlay (relatively) you can have a lot of fun, finding what you like best.
