I have the 5.4's and I wouldn't decribe them as thin. I only got them from here actually, a few weeks ago, and they're a lot warmer than the Special 25's they're replacing. I also have the little Contour SR's, and they're a little warmer still (with a Velodyne DD15 sub). The treble is nicer, smoother more detailed on the 5.4. Better than the S25 even though its the same tweeter. In fact the treble is nicer on the SR's than the S25's in my room, and the SR's have the lesser tweeter.
I have no problem with the 5.4's midrange. The S25's were definitely too forward for me.
For your interest, I'm using the BelCanto eVo2i and Arcam FMJCD33.
