I also had the same dilemma. I am now the happy owner of the 12L's. I would say the 52's are closer to the 11L's in most aspects, but overall i'd choose either Quad over the 52.
Dynaudio Audience 52 or Quad 12L?
I'm trying to decide between Dynaudio A52's and Quad 12L's. Anyone compared the two and have an opinion to share? I have listened to the Quad 12L's and Dynaudio Contour T2.5 but not the Audience series. I listen to many types of music. Power amp is undecided at the moment.
