Speakers for bad rock recordings

I'm kind of stuck, my music collection is about 90% average and bad recordings, some very bad. I listen to a lot of rock, metal and punk. I live in an apartment too, which means I want them to be able to sound good at moderately low listening volume. I also like 'live' sounding speakers like my Klipsch's, but they do create a alot of fatigue.

I really like the way my Grado SR80's make even my worst metal recording sound good, so I was thinking maybe there's a speaker that's similar? Right now my amp is a Onkyo A-9555, which is neutral sounding and has about 85 real wpc.

I can only afford to spend about $600, maybe a little more if I have to.
