I love my Dynaudios. I have the 70s. I have heard the 52s and I love the Dynaudio sound. I would buy them again in a second. I have not heard the Europas. I have heard the Dyns with the Arcam, but I am driving mine with an Aragon/Outlaw rig. Does the Arcam have enough power for you? The system I heard was in a small room. Good luck!
