I currently own the Proac D 40r. I owned a number of speakers before that with many of them from Proac (including the Studio 140) as well as other brands such as Spendor 9/1, Harbeth 7, Joseph Audio, Rogers B&W, Dynaudio, and Celestion, etc.
I kept returning to Proac, which apparently suits my ear best and has some synergy with other equipment I have owned.
Good luck with your search.
