Greetings YYZ,
I've noticed exactly what you're talking about with Rush recordings - many otherwise fine-sounding systems sound lifeless with Rush. I don't think the entire answer is necessarily a forward tonal balance; rather, I think it has as much if not more to do with conveying the dynamic inflection of the musicians.
Rush uses dynamic nuance to convey rhythm more than most rock bands, and if the system doesn't get the dynamics right Rush will let you know. One of my test songs is Dreamline off of Roll the Bones, which sounds awful if the dynamic shadings are opaqued but magnificent when it all comes together. Then once the system is working well, I'll put on Camera Eye and turn out the lights and leave the world behind for eleven minutes or so.
Now the primary enemy of dynamic contrast is thermal compression. That's where the voice coil heats up (virtually instantaneously) from a music peak, which causes its resistance to rise. When the resistance rises, not only does it now take more power to overcome that resistance but most amplifiers will actually put out less power into a higher resistance load. In my opinion the answer is high quality prosound drivers (which have negligible thermal compression at normal in-home loudness levels) ideally combined with an amplifier that does not deliver reduced wattage into a higher impedance load (such as an SET or OTL tube amp).
