Am I the only one to opt-out on the Sopra 2's?

I home auditioned a pair of broken-in Sopra 2's for over a week (Clayton M 100's and Naim 272 pre).  I began by loving them but then gradually found them fatiguing.  Then I noticed that I'd been making excuses for them when high notes became painful and the sound stage seemed blurred.   So I tried Dynaudio C1's, also broken in,  and everything was suddenly better.  I ended up with C2's  and could tell a difference even when they were not broken in. All of these speakers were auditioned with a REL subwoofer.  In the end, I not only disliked the Sopra's, I disliked them a lot.  All the Sopra reviews seem to be generally favorable.  I know I'm probably in a minority, but in my system, the Sopra's were a failure.  Its been suggested that my reaction was because I was  used to the Dynaudio tweeters in my Merlin VSM's, but I think it was more than that.  Anyone else have a similar experience?
