I asked @J.D this question in another thread and he was kind enough to reply:
Both speakers deliver the best sound for money ive ever heard. They actually (to my ears) sound very alike. Transparent with a tweeter that never becoms to harsh .
Genelec 8361A has a slighly better soundstage due to the coaxial design. The midrange on the 8361A is also just a bit better , more open , clearer.
Both speakers are really good, but you need to integrate them to the room via DSP . They become twice as good then. It´s day and night in difference .
