Believe me, the Utopia will seems like another pair of headphones after a couple of hundreds of hours. I found the mark of ~ 500 hours to be the most significant. They sound is now much smoother, refined anf fuller. But still with incredible transparency, clarity and details.
After only about 100 hours or so, I didn't really like them and I would have desribe the sound as really similar as you are experimenting right now. Bright, revealing and a bit thin and bass shy. I would even go as far as saying sterile. At a point that I put them on sale on a canadian forum as I was a bit in a panic with the disapointment of such a big purchase. I received good and serious offers for them. Some members of this forum wrote to me to say to be patient and I will be rewarded. I also remember my own experience with my Focal Utopia car speakers with Beryllium tweeters. It took about 3-4 months to sounded really excellent in the high frequencies.
I'm really glad that I have been patient.
