Everyone has an opinion but Dynaudio do not excel at low volume. I sold a pair of Evidence Temptations for that reason. Plenty of high end brands need the volume up a bit to sound great in my experience.
Klipsch might be known for brightness as a brand but I heard the Cornwalls today at a dealership and they were downright smooth. Classe amp powering them. Probably not what the OP has in mind.
