I second the PMC recommendation. The new i series has very easy to listen to highs but they do not sound rolled off. Just really well done.
I can't say what the older series' highs sounded like, since I've only heard the i. The + series (before the i) added a soft dome tweeter, and the series before that had a metal tweeter. When the + series was introduced, you could actually upgrade to it if you wanted to change the metal tweeter. As far as I know, the + and i tweeters are different. Reading online reviews, many PMC users did not think the metal tweeter was too bright, but unless you hear it I guess that's one risk with a metal dome.
Anyhow, PMC mids are full, with great instrument separation that makes it easy to follow each individual part. Bass is deep but tuneful. Overall it has a nice, wide open and balanced sound with fantastic resolution. I also listen mostly to rock and the i series does a bang up job with that genre.
