if you're wondering about the 60's and brightness, to me it is no longer an issue. when i first hooked up my 60's to a yammi receiver, which are said to be bright, they seemed harsh, and the wow factor was not present. after a few weeks i guess they seemed to soften to me; i have the trebel maxed out on the receiver. when pared with a sub, and set to small, everything sounds terrific. now that is no to say aerosmith sounds laid back. i do turn down the treble when steve screams, i mean sings, some tunes. my wife and i now prefer not to listen to some of our older cds that were recorded poorly. so...go for the 60's crank them until the neighbors complain, and enjoy.
