of the cd's you mentioned, i would expect for the kinks and zep to sound bad.. its not the speakers, its the recording.. those old rock recordings on the old analog equipment are not the best in the world. and it depends on which clapton you were listening to. if it is an old recording, then expect much of the same. the speakers are accurate enough to reveal the short comings of bad recordings.
try some newer rock stuff and see what you think. few suggestions...
queens of the stone age(songs for the deaf)
pearl jam(verses album)
AC/DC(back in black)
metallica(black album)
give one of those a spin, and then see what you think..
