I suspect for some engineers and producers, compressing and brickwalling go somewhat hand in hand. After all, if you’ve reduced or removed the dynamic range, why not just bump the volume so that's not a problem either?

My personal opinion is that Intrada is already doing the right thing. Please don't change. You release albums from a variety of decades, and the older material (especially the wonderful sounding stereo material from the '60s we've gotten in recent years) deserves – after so long without an upgrade or any CD release at all – to be heard with their original dynamics intact. Some might even consider compression an unjustified alteration to the intentions of the original artists, which history indicates is never a popular choice in the long term. Likewise I suppose if '80s or '90s albums were originally compressed, the authentic thing to do is retain or recreate that. Is that what Intrada elected to do with The Rocketeer? (EDIT: I see it is.)
If you don't mind, I’m going to mention this on the FSM board to generate more discussion as not everyone there may see this. I'll put it in the Rocketeer thread.
