The remaster of KEA sounds really good from what I've heard. Not much louder, but gives a boost to certain frequencies that brings out the crunch of the guitars and the clarity of the bass. I'd actually favour that over the original CD release.
The remaster of RTL is just crushing the dynamics. It doesn't sound terrible, but the original pressing sounds superior. What you'd expect from a modern remaster, unfortunately.
MOP does sound great as is, although like KEA they could potentially make it sound even a little better. I expect it will end up more like the RTL remaster though. No big loss though, the original pressing sounds good already, so I'll keep listening to that.
I'm still curious to find out what they do with AJFA. It's a real opportunity to correct a major production fault and have the mix fixed, perhaps as a bonus disc to a more standard remaster for those who want to hear it unaltered. I'm getting my hopes up big time with that wish though.
