I think the element being not mentioned enough is that rock n roll is usually played loud and is not that sonically nuanced. Much is electric and the drums are simpler and less sophisticated.
That's quite a generalization! But the fact of the matter is that rock recordings are all over the place in terms of quality. If you are presuming that one *only* listens to the poor recordings and *never* the good ones then this might work.
I play lots of rock recordings at audio shows as demonstration. Not because they are 'not sonically nuanced' but because they sound good and show off what a good stereo can do; here are some examples:
ELP, self-titled, Pink Island edition
King Crimson, Islands, Atlantic white label promo
Steve Tibbetts, 'Yr' self released
Steve Tibbetts, Safe Journey, ECM
Black Sabbath, Paranoid, white label German Vertigo
Porcupine Tree, Voyage 34, Delerium
The better the system, the better these LPs sound!!
Whatever can play classical well should be what plays rock well as well. Speakers don't have taste- people do.
