Let me throw this out for your consideration...the ear/brain wants to hear a balance....bass and treble. If for some reason...room, speakers, positioning, etc. there is not enough bass, then the treble is perceived by the brain as being "too bright".
Before you give up on the Zu..s, you might be surprised by what the addition of a sealed subwoofer will do to the overall balance of the sound....with a sub it will seem more open, smoother, less bright....and with the kind of music you prefer, you will be happy you retained the Zu punch which you are less likely to get from any of the speakers you mentioned.
Steve59 mentioned that in his case, he had optimized to get results down to 20hz which made things rattle and not seem musical....my suggestion would be to run the Zu...s full range and then bring the sub in around 60hz and just turn it up slightly...not to shake the room but to add that little bit of deeper low end you are missing....and then after a few days you may turn it up a little more...or maybe even back a little more...but with a little tweaking, you can get a really good blended sound with the Zu..s
Good Luck
