IIRC, there was another curious effect on the DVD-A of Fragile - compared to Gaswirt, some of the drum hits were peaking notably higher relative to the rest of the instruments, and yet the drums are much more compressed on the DVD-A. One could go both ways on that, and say that either the amount of outright compression is higher on the DVD-A, or that the limiting itself is not that strong, and so it might be arguably more dynamic.
Do you have any samples from the recent MVI discs - I'm thinking of Rush's Snakes and Arrows release on the MVI, which contains a 5.1 mix and a 2 channel 24 bit stereo mix? I'm at work, can't download and rip anything now, but would be curious to see the result in terms of waveform. The cd of Snakes and Arrows sounds terribly smashed and slightly distorted in some spots.
