I once owned the Plinius 8200 MKII, which mated nicely with Dynaudio 1.3SE's. Being a long time fan of Dynaudio, and given your mention of finding the Dynaudio house sound appealing, I would agree with Missioncoonery on choosing the S5.4 (or the S3.4).
The other suggestions of DeVore & Coincident are also very fine choices, and give you added flexibility down the road if you'd want to switch to a medium powered tube amp.
