I’ve had Dynaudio Contour 1.3 mkII in the same 12x12 room as the ls50s.
Different sound. Dynaudio was a tad warm and could lean towards a tad bright in some cases. Bass was more extended. I didn’t use a sub with them. I do use sub with ls50s. Ls50s are a different sound in most every regard. Definitely more detailed and different imaging. Probably also more coherent. I liked the Dyns a lot but do not miss them with ls50 + sub combo. Without a sub, it’s more of a tossup depending.
