I have def techs as you can see in my signature, I think they sound great, but the mains are a little finicky on placement, once you get them set up properly they sound fantastic (IMHO). the center channel has added great depth to voices, not unnatural. the only negative I can think of is they all have to be plugged in so you need outlets close by, as the cords are not very long, and if you are tight on space, thier fairly big. hope this helps.
