Usher Mini Dancer 2 or Q Acoustics Concept 500 - Marantz PM Ki Ruby

Congrats, Usher speakers are competitive with anything you want to put them up against at a givin price point. 

My BE 20 DMD's used the same tweeter and were highly detailed without sounding bright so I would agree you're just not finished with placement yet. Regarding break in...I did have 1 pair of speakers, the KEF R105/3 that seemed to take forever for the high fq's to settle in, otherwise more often than not I find placement and component matching make the biggest difference and regarding a bright or glaring sound that's most often an effect of reflected sound and pulling speakers a few feet away from sidewalls and tv monitor, if after the 200 hrs still sound harsh, helps.
