I would guess that something like that would be the way to go. People say the cca dac is pretty decent so cheap upgrades don’t give significant results. RPi based stuff does have a rep for punching above its weight price-wise so hopefully you’d get a decent improvement.
For my TV (as an example of lower res inputs) I run from the headphone socket using its own DAC into the amp, mostly so I can still use the tv remote for volume, but it sounds very good for movies where impact is more important than fidelity and for radio which I very rarely listen to without doing something else at the same time, unless it’s test match special. That’s probably a similar oem DAC implementation as the CCA.
Just as a matter of idle curiosity, what is TV audio these days? The last time I had one, it was NICAM, which I understood, but I have no idea what's in a DVB-T stream
I’ve no idea but it seems to get better with picture resolution, ie blue ray is noticeably better than broadcast Cash in the Attic on Virgin fibre optic.
