When it comes to using these speakers for HT purposes, I honestly can't find any fault - even if I try. It makes me wonder if designing speakers to reproduce movies and music requires a compromise in one to benefit the other.
What you are discovering is Audio Compression...certain forms of music are highly compressed. Eva cassidy is not. Movies are not. This is why they sound good on your system.
Hyper compressed rock, pop and alternative is common these days and it will sound fatiguing. Switching to a less accurate speaker with laid back midrange and smooth warm sound may help...but it is a "band aid" not a cure...besides do you want to put a band-aid over the beautiful sounding Live at Blues Alley - just so you can play Metallica without having to cover your ears - the choice is yours...
