It will be interesting to see how that big box is mastered. That whole ‘90s Bowie era, whilst containing some real gems, is pretty brick-walled. I’ve got the previous CD box set where each album was expanded to a double with 12” mixes etc and it certainly isn’t great dynamically, and gets worse as time goes on (i.e. the later albums are more squashed than the early ones). I suspect it was just a mastering/aesthetic decision so is baked-in, but it will be interesting to see if the DR values change.
PS I’ve not bought any of the boxes as I consider my Bowie to be on vinyl, that ‘90s box is actually the only exception as I wasn’t paying attention at the time and hadn’t realised he’d got good again!
