I will do a comparison this weekend between the standard cd, HDtracks 24-96 download, and the MSFL cd.
Just bear with me as it will need to happen between the kids soccer, MLB playoffs, NFL, etc...

I was able to listen to all three versions over the weekend and come to a few conclusions.
While the MSFL version has better measured dynamic range, the added clarity of the 24-96 download from HDtracks made it the one I wanted to listen and rock out to. When doing quick A/B comparisons (which I could never absolutely level match due to the loudness differences and the way volume control works on my preamp), I "think" I could hear the dynamic range differences, but it wasn't that super noticeable and it didn't detract from my enjoyment of the music.
Both the MSFL and 24-96 download were better than the original. By comparison, the original sounded muffled and congested. I didn't notice any differences in regards to instruments used, placement of instruments, voices, etc...they are seemed to be the same.
I do want to stress that the HDtracks version is significantly louder than the original or MSFL versions, so be careful with where your volume is at before hitting play!
Other than the very loud nature of 24-96 download and the more limited dynamic range, I think they did a pretty good job creating the hi-rez release. If you are a fan of Nirvana, it is worth buying.
