Okay, I've analyzed this and re-re-retweaked it in Audacity literally about 20 times.
What I've come to find:
1) The front mains are very hot, yet just short of clipping (probably limited), so I based everything else around them.
2) The center channel is the
only channel that has dry vocals (and has a bit of bass guitar and kick too), but is very low in the mix, whereas all other main channels have wet reverb/delay effects (especially the rears). Turning this channel up actually makes the reverby stuff seem much less overbearing. I'm not a huge fan of just cranking James LeBrie's vocals, and on most of their other recordings he does seem to be mixed more balanced with the instruments instead of being overly prominent, so this took some judicious level adjusting to bring some focus and clarity without over emphasizing the vocals.
3) The LFE (.1) channel has a good bit of bass guitar and kick drum fairly equally balanced together (which is not always the case), but it is very low in the overall mix and sounds rather thin. I'll admit that I'm a basshead, and at one point I increased this +12dB and it still wasn't anywhere near clipping since the level is so low, but trying to be more reasonable, I used +7dB as a standard setting to keep things ballsy and deep, but still fairly balanced.
4) The rears do have quite a bit of discrete information going on, along with lots of wet effects on lots of stuff, but overall is still very low in the mix. This was quite tricky to try to bring out the surrounds a lot more, which was sorely lacking, without over doing the splattery reverb. Too low and the discrete sounds aren't balanced with the fronts, too high and the reverb was too prominent.
Here's what I've come up with on my particular setup:
...
It's not perfect, and I may end up tweaking it a bit more before I'm done, but for me, these settings have taken me from a rating of probably about a 4 or 5 to maybe about an 8 or 9. I love the music, and this makes the mix much more tolerable. If anyone has any suggestions let me know, and if anyone wants to try out my crazy remix, send me a PM. Thanks for reading!
