I've heard these speakers and also the Dali Zensor 7. All good speakers. The Zensor 7 good; but the other two better. Voices sounded much better. The Dali Opticon 6 maybe the highes are smoother but the Tannoy sounded more lively and more dynamic. The bass from the Opticon a little disapointed from their size. But very difficult to decide which to choose. The Tannoy for 1000,-- Euro or the Dali Opticon for i think here for 1350-- Euro. My amp Exposure 3010S2 and music from bands like Nightwish, Sirenia, Hammerfall, Epica.
