Gawdbless, I philosophically disagree with you, as I don't believe it's reasonable to expect speakers to "enhance music". If a speaker accurately portrays a recording for better or worse, I think it very fair to blame the recording in some instances. If one needs to tamper with a recording to make it palatable, I think there are better devices with much more specific controls available to those that feel the need for such things, than speakers. One good example of a recording that that can sound a bit hard is Miles Davis' "Sketches of Spain".
I'm with Unsound on this one, except for the comment about Sketches of Spain. I have original vinyl on that and its got no harshness at all, so long as the system I am playing it on can track it. It *does* have a lot of energy...
