@richardbrand - and followers of this thread more generally...
The majority of commercial digital recordings will go through a few a/d and d/a conversions. This is because most studios use lots of analogue outboard gear - so at tracking the signal will be converted to digital. At mixing it will go a/d to the outboard gear the d/a back to the computer. At mastering, it will go through the same process.
There are studios and mastering houses which operate entirely "in the box" i.e. do all the mixing and mastering using the computer alone. But it's still a minority.
Back to Brothers in Arms - the DDD means that it was recorded digitally, mastered digitally and output on a digital storage medium.
But that cannot be taken as a guarantee that the signal was never in the analogue domain during either the mixing or mastering process.
The state of computer technology at the time would not have made it feasible to mix it digitally, and it wasn't recorded to hard disc in the first place anyway.
