A friend tried several (all of the ones you mentioned plus a few more) in his system (modwright pre and cdP with B&W 803N's) and didn't purchase any of them. He too was looking for the same type of sound your described. I was there for all the A/B comparisons and reached the same conclusion...that Class D's show promise but not today, not now in the system we plugged them into. Hopefully in the near future they will blossom. Of all the ones we tried, the Hypex /UcD designed based ones were winners over the ICE and in-house based amps.
YMMV so you will need to audition them in your system to see if they have synergy with the Sonata's. All the post above indicate this.
Good luck riding the merry-go-round of audio equipment change.
